Title: Celestial Objects Thread
Post by: Herra Tohtori on August 31, 2006, 12:06:38 pm
Well, I came across an excellent GIMP tutorial on how to make planets (http://www.gimptalk.com/forum/topic/A-Better-Planet-Tutorial-5221-1.html), so naturally I wanted to try myself what I could accomplish. The results I got with following the guide didn't actually satisfy me, so I came up with a little modified technique. I got some pretty rocks made... I wanted to try and make Earth-like planets at first, because they are IMO the most complex to make.

Then I came here looking for a nice thread featuring planets and stuff, but I didn't really find one! All were like year or two old and had mostly dead links and some people who I've never before seen here, so I decided it was time to make a new topic for planetary art that HLP user pool spews at random intervals. I'll start with two of my planets I made yesterday and today.

So, first planet looked like this:

(http://users.tkk.fi/~lmiettun/Kuvat/Space/planeetta_2_thumb.jpg) (http://users.tkk.fi/~lmiettun/Kuvat/Space/planeetta_2.jpg)

Don't let the number 2 in file name to distract you, that's because there was already an older planeetta_1 file in the dir.

Well of course I wanted to try and make it even better. This time I spent more time with the surface map, putting in mountains and ice caps (which were after all mostly non-visible), and more defined seas and continents. I also spent some time to create a more complex array of clouds, and behold, this was the result of 2nd attempt:

(http://users.tkk.fi/~lmiettun/Kuvat/Space/planeetta_3_thumb.jpg) (http://users.tkk.fi/~lmiettun/Kuvat/Space/planeetta_3.jpg)

The shadow layer seems to be a bit off for some reason... I'll have to give it a fix. Both of these planets can also be shown without the shadow, or they can be fitted with any kind of a shadow layer I can think of. Though that would also mean that the diffuse atmospheric glows should be re-made...


So, what do you think? Also, feel free to post your own planetary creations and stuff. After all, I personally think there's a little too few planets around in Freespace...

Not bad, Herra Lekuri. Your planets have a  really artistic feel to them.

As it happens... I just finished this piece:

Then a planet that is almost a year old and thus ancient history on my scale, but still one of my long time favorites.

Beautiful... :nod:

Remarkable how different planets come out from different people, eh?

Did you use actual Earth world map in that High Orbit picture? I'm having some difficulty finding a high-res picture of earth. Of course, I could use whatever kind of surface map.

Actually I found out today that GIMP is a very wise thing for free program (even more so than I thought previously).

You can import any planet's surface map in high-res, resize it onto a square, make it seamless (not even necessary) and then do map to object (ball)... And it creates a planet that has correct continents and stuff, like you planned it onto the level map. Cool thing.

Another question - did you use bump mapping to the cloud layer? I did, and it ended up much better looking than without. After all, clouds are higher than ground (usually). :D Oh, and would you want to reveal how you make that nice blue atmospheric diffuse light that strengthens in the distance? It looks so real that I almost fear my screen will break and the air in my room be gushed into vacuum... well, not really, but almost. :cool:

Wow, those are really beautiful!  I'll give this a try tonight when I've got more spare time and see what I can do with this.

Looking through that tutorial, I noticed that the method of making the planetary shadow is a bit flawed.  If you look carefully at a real planet shadow, you'll notice that it's not the same as a dark circle superimposed over the planet's disk.  That said, it's still very cool and I'm just letting my perfectionistic astronomy nerd of an ego complain at it.  ;)
Title: Re: Celestial Objects Thread
Post by: Herra Tohtori on August 31, 2006, 03:20:42 pm
Well...

There's nothing wrong in itself if you put a circular shaped terminator onto a planet.

The only thing is that the border of light and dark must divide the ball into half. That means that the only really important points are the points where the shadow starts on the edge of the planet's visible half. The line drawn between these two points must divide the visible half of the planet into half, if there is a shadow visible. So, you could use the rectangular selection as long as the direct line draws the planet into half...

I don't know if I got this explained as understandably as I wanted, but if you don't get it the reason is not in you, but in my Enklish tongue. :D I'll post a picture of how a spherical object creates a shadow, if you don't understand my gibberish.
Title: Re: Celestial Objects Thread
Post by: watsisname on August 31, 2006, 03:57:58 pm
Yes, I more or less understand that.  :)

Hmm, I gave that a bit more thought.  It turns out it DOES work out correctly (using a circle to make the shadow), but the radius of the circle will vary depending on what the percentage of the planet's disk (relative to the observer) is in shadow.  The more of the planet is in shadow, the smaller the radius of the circle. 
Also, if the illuminating object (sun) appears as a point in the sky, then the two points where the terminator line meets the edge of the planet disk will be directly opposite each other, and the terminator line will be crisp. (I think that's what you were referring to in your post) Conversely, the larger the apparent size of the star, the more "blurred" the shadow line is, and the shadow/planet-disk intersection points will be close together (further toward the dark-side of the planet).

...I hope that made sense.  :lol:

Oh, some pictures of the lunar phases to go with what I'm saying.  Notice that you *can* use a portion of a circle's arc to describe the terminator line, and the radius of that circle increases as the area of the moon that is covered in shadow increases.

Post by: Herra Tohtori on August 31, 2006, 05:14:16 pm
The sharpness of the terminator is more linked to atmospheric qualities of the planet than the apparent diameter of local light source.

Of course apparent diameter also affects, but atmosphere has even bigger effect. Take a look at moon and you see much sharper terminator than on pictures of earth. Conversely, if you go to Jupiter distance and look at Jupiter (whopping big and dense atmosphere) and some of the barren rocks they call moons (say, Callisto or Ganymede) and the shadow is much sharper again.

Though there aren't completely sharp shadows anywhere in solar system due to the nature of the surfaces of planets/moons.


Oh, I decided to experiment with the "Render to Object" function a bit... I used THIS (http://users.tkk.fi/~lmiettun/Kuvat/Space/EarthMap.jpg) as the starting point, and ended up with this...

 :D

Aside from some polar squeezation I say that GIMP is a very useful tool. I mean, look at it. It looks like a planet to me...

Hell, I could scan some old maps from various fantasy book series' and put them into planets, and if someone recognized them I could well give them cookie or two... :lol:

Woohoo another GIMPer! I am not alone!

That said, nice planets. And nice tutorials too. I never used that "map to object" thingy and I was doing all the "sphere" look with lens effects. Well, it's sure nice to learn new thechniques like that. GIMP rocks.

Keep up the good work!

I actually use Lightwave to render the planets, so ours are not directly comparable. I've done some PS planets though, and my general feeling is that using pure 2d results in more "artistic" looking planets. If you want realism, 3d is the easiest way.

8k color, 8k spec, 8k bump and 16k clouds, plus some additions procedural textures on the clouds and spec layer. I would have used 16k for all, but LW crashes when I try that :)

As it's done in LW, I can't help you much with GIMP.

You have no idea how long I tweaked that atmosphere to get it about right. And the colors look all wrong if I zoom out with the camera and look at the sphere from a distance.

The GIMP (http://www.gimp.org/). :nod:

If you are used to more of a classic interface, get GIMPShop. That you can find from HERE (http://www.gimpshop.net/) or HERE (http://plasticbugs.com/?page_id=294). It basically makes the main GIMP window more of a traditional image editing program's main window.

I like using the normal GIMP, though.

Can we release the .pcx images for these planets? They sure beat most (if not all) of the planets currently available...


On the other hand.... FS only allows 16-color background PCX's, which sucks.... that might become a problem.
Title: Re: Celestial Objects Thread
Post by: Herra Tohtori on September 01, 2006, 06:07:37 pm
Skyboxes with textures are the solution to that problem...

AFAIK they use similar (almost) textures than the models and effects, and textures can be practically as good as you can make them, for example 32-bit DDS (or are they actually 24-bit...?) or TGA pictures.

Anyway, skyboxes are quite a lot better in most regards as backgrounds than traditional background images, as far as I know. I'll have to check the wiki if there's a skybox howto/description...

Never ever use 256-color pcx images as backgrounds again. Use 24bit dds for nebulas, 32bit dds for planets. You need the alpha channel in planets or you'll get an ugly black box. 1024x1024 is good resolution most of the time.

Normal backgrounds are still very good if done right. Skyboxes are good for special cases, like a mission taking place very near a planet. Here's how I did the big gas giant skybox for the BtRL:

(http://i27.photobucket.com/albums/c189/LtCannonfodder/Other/skybox.jpg)

The outer sphere is inverted and mapped cubically with a 2048x2048 starfield texture. The planet is just a flat plane, texture is also 2048x2048.

Well, now I know more. Thanks. :D

By the way, I created an image of MArs for comparision purposese between LW and GIMP in planet making. Not to define which one is better or worse, but just to find out differences and perhaps use that knowledge in GIMP to make the result even closer to realism factor achieved by 3D software.

Here it is:

(http://users.tkk.fi/~lmiettun/Kuvat/Space/planeetta_5_mars_thumb.jpg) (http://users.tkk.fi/~lmiettun/Kuvat/Space/planeetta_5_mars.jpg)

It's the God of War on his more stormy season, apparently.

Oh and by the way, I figured out a theoretically perfect way to generate correctly shaped shadows. It goes like this:

-create a new white layer
-slice the layer in half vertically
-flood the other half with black and leave the other half white

-select Map to Object; rotate the half-white, half-black ball until you find a good shadow shape

-make white part of the picture transparent

-blur the edge of shadow crossing the planet's sphere. There. I used this method with that Mars pic there.

...oh, and very many thanks to Lt.Cannonfodder for reminding me of Celestiamotherlode. Excellent content there, if you want to create planets of the solar system.  :nod:

Post by: watsisname on September 02, 2006, 05:28:00 pm
Would anyone mind sharing some techniques for making good atmospheres?  I've tried bounding the planet with a mostly transparent white layer with gaussian blur, and placing that layer below the shadow layer, but I'm sure there's a better way of doing it.
Title: Re: Celestial Objects Thread
Post by: Herra Tohtori on September 03, 2006, 02:26:24 am
Surrounding the planet with white blur kinda works, but the rouble is that it also reaches to the shadow side, which is sort of unrealistic.

Here's what I do... When I get everything else sorted out onto it's place - surface, clouds, shadow - I choose "Copy Visible" or whatever it is in English version of GIMP. That copies what is currently visible - a sharp-edged planet, that is - onto clipboard.

Then I create a new layer behind th esurface layer and paste the clipboard information there. Then I Gaussian Blur this layer on about 50-100 strength, depending on thickness and density of the atmosphere. There is the surrounding atmosphere you're looking for.

It does not hinder the visible part of the planet, because it's behind the surface layer. However, it reaches some distance away from the edge, making a low opaque atmosphere which is roughly the same colour as the planet.

If I want to get some atmospheric effect onto the surface also and not just edges, I duplicate this same layer, move it just behind the shadow layer - meaning that it is over the cloud level - and set the layer mode to Soft Light. That does an interesting effect, for example in that Mars picture it made the clouds more dusty yellow. Tryi with this kind of things yourself... I've noticed that it's very very hard to set up a good-looking uniform colour blurred atmosphere. Though I would suggest trying making a circular gradient field that is most transparent at the middle and gets thicker going towards the edges... Choose a colour that fits the composition of planet's atmosphere. Then blur this layer and place it on top of cloud layer, and adjust the colours and opacity of the layer until you get good results.

Earth atmosphere is sky blue, Mars atmosphere is probably bluish grey in reality... though it's so sparse that it hardly has much colour into it. Titan should have thick, orange-ish atmosphere. Try different styles, but I use the technique I mentioned first, it's fast, simple and gives satisfactory results.
Title: Re: Celestial Objects Thread
Post by: watsisname on September 03, 2006, 03:13:53 am
Ok, thanks very much for that info.  That totally sounds better than what I was doing.  :o
And expect some more pictures from me whenever I get more time to play with this.

Edit:  Um, wait a moment.  The method I was using doesn't have atmosphere effect on the darkside, since it's covered by the shadow layer.  Observe:
(http://img312.imageshack.us/img312/1915/iceplanet6il5.th.jpg) (http://img312.imageshack.us/my.php?image=iceplanet6il5.jpg)
Er, well in this case it's slightly noticible since my shadow layer isn't at 100% opacity.  I usually like to have a tiny amount of "abient light" on my planets.
And yeah, I got starfield-making down pretty good now, too.

Edit2:  And here's my latest bit of work.  Needs some touchups with the nebulae, perhaps, but I quite like it. :)

Post by: Herra Tohtori on September 05, 2006, 11:51:20 am
Yep, if you make the shadow as a big enough oval selection that extends way over the borderline of the planet, then the problem with the grayish blurred atmosphere effect is wiped out because the shadow indeed covers it. And you can of course manually wipe out the dark side atmosphere effect.

But, by blurring the sharp-edged compsition of surface, cloud and shadow layer as one bunch and then blurring it, you do get an atmosphere effect onto the shadow side - but it consists of blurred black so instead of shining against black background, it should somewhat darken the stars behind it.

How do you make starfields? I simply put uniform noise on black background, then adjust the brightness and contrast higher... Usuall Brightness value is somewhere around 70-90 and Contrast on 110-120, depending on picture size and other things, like how dense a star field I want.

And yeah, those nebulae seem to need some work. I see you used much similar method in creating them as I do. Plasma clouds are very useful. Did you use the Colouring tool to make them blue? If so, I think you need to boost the colour saturation and reduce brightness. Or just blur the nebula layer, and place some stars inside (->below) the brightest areas, so that there's an actual reason why the bright areas are bright. Like here:

(http://users.tkk.fi/~lmiettun/Kuvat/Starfield_3_small.jpg) (http://users.tkk.fi/~lmiettun/Kuvat/Starfield_2.jpg)

I put this nebula pic together back last winter. It's a rather good default background for space objects, though I often use just starfield.

Post by: watsisname on September 05, 2006, 04:37:00 pm
It seems both methods for making atmospheres work quite well.  The disadvantage to making a blurred layer surrounding the planet is, as you said, that it requires and extended shadow layer to cover it for the nightside.  I think your method sometimes works wonderfully for planets where the surface and/or cloud layer are not very highly contrasted.  Meaning that, for example, if the surface has very high contrast between dark areas (like land) and light areas (ice or snow), then those contrasts will be carried over to the atmosphere as well, so an extra step or two is needed to correct it.  (Not really a problem, just takes a bit more time.)  Of course, it may work awesomely if you're trying to get the atmosphere effect to match to surface features.

As for the starfield, I used noise > hurl, then desaturate, colorize, and then used layers > colors > curves to choose a specific number/brightness of stars to show up.  A little experimenting will show some cool ways to change the starfield's density and randomness. 
For your starfield, how did you make the larger stars?  I've tried a few settings but I must be missing the technique you use.

And yeah, I used colorized plasma clouds for the nebula, and changed the layer mode to "hard light".  I'll try your suggestion of altering the brightness/contrast and see how that works out. :) 
Hmm... I just realized that with a little editing, those last background nebulae I used might make a very nice galaxy band effect (as in it looks like the Milky Way when viewed from Earth).  Maybe throwing in an extra layer with some small red emission nebulae could improve the effect?  Ooh, something extra for me to experiment with. :D
Title: Re: Celestial Objects Thread
Post by: Herra Tohtori on September 05, 2006, 05:28:56 pm
Big stars:

- make a new (transparent) layer, then I put some white differently sized flecks on the layer with the "P" tool, whatever it is in English version you get it via P key. Choose the fizzy edged pencil, try different sizes and click the mouse on same location for a few times if you want more defined stars... The more clicks, the sharper edge, but you can also choose the sharper edged tool and try with that.

Choose the locations for stars according to bright parts of the nebula, but don't put in too many stars, it ruins the effect usually.

Then duplicate this layer, blur it some amount. Adjust contrast so that the blurred round flecks are little more visible than what they initially are after the blur.

Now colour the blurred stars with same hue that you used to the nebula. This is quite important... the brightness is usually good as it is, but change the saturation to maximum or near maximum.

Now, if you have the starfield as a background and the nebula layer on top of that, move the initial star layer over the starfield, then move the blurred layer on top of that, below the nebula layer.

I use normal mode on all the layers whenever I can, and I rather just change the nebula's black colour to transparent than fiddle with layer modes. I feel it give sme more control over the final result.

Oh, and btw I think you may want to try a simpler and faster method to create a star field. Just make the default noise (with united RGB channels, so the noise is gray), then simply adjust contrast and brightness according to your preferences. Why the need for hurl? And colorize? AFAIK most stars are quite... uniform white, with just the brightest ones making a notable exception to human eye.

Just use the skybox technique, Its still wrapped around a ball, Just the inside of the ball.
Title: Re: Celestial Objects Thread
Post by: Herra Tohtori on September 06, 2006, 08:48:56 am
CD... you seem to have no clue what you're talking about... :lol:

The tutorial by MarvinX doesn't concentrate very much on creating the actual texture. It's a very simplistic method in fact. And regardless of using background or skybox technique, the images must still be made. And that's what this thread is about...

I'll post something considering my experiments on the subject later today. But as a tip: using plasma, colorize and brightness/contrast you can create continents from the bright areas of plasma cloud and thencoulour the continents gray/light brown. Then use freehand selection to choose which areas are forest, which are mountains etc. If you want, create valleys and stuff onto mountain areas, and perhaps some rivers onto mainlands.

If you want to avoid exessive spoilage around poles, simply put ice caps or open sea there. They are the easiest way to avoid ugly thingsies from forming on the pole.

Besides, I don't think it would even be good to always use similar method to create planet texture. It would result in massive amounts of generic planets, something I personally am against. Different kinds of methods create variety.


Though, creating gas giant textures is easy compared to earth-like planets or plain barren rocks. Just create a background layer of arbitrary colour, then put one or two cloud layers on top of it. IWarp works well in creating belts and zones on cloud layer, just slowly move mouse vertically, clicking occasionally. Then move to other zone, change the direction of swirl and move to other direction, still clicking. Cover the whole planet like this. Shadow layer goes on top. This creates a nice, Jupiter'esque planets; other gas giants in Solar system are much less detailed. Saturn has rings, but Uranus is just a blue blob and neptune is not much better. The other one of them has some white storms on them, but that's it. They look dull... and that makes it more difficult to make them look interesting. ;7

One more thing that is easier with gas giants. Atmospheric effect is so thin that it's usually not noticeable, because the planets themselves are so frakkin huge that the width of atmosperic effect would be about <1/1000 of the planet's apparent diameter, so it's just not visible. They are just sharp edged spheres or ellipsoids, making them much easier to create. I might do some gas giants next...

Yes we do...

But I don't really understand what you want us to do.

<iron wire>

It doesn't matter whether or not we use skyboxes or traditional backgrounds as long as it looks good.

But, I say again, regardless of the technique to use the images in-game, the images must still be created.

It is easy to map a texture to sphere.

Before mapping the sphere, you must create the texture or use existing one.

It is not as easy to actually make that texture.

That's what this is about.

How to make a texture that looks like a planet when it's mapped to a sphere.

EDIT: And, if you just toss the planet texture onto the skybox, it'll look like you are flying inside the planet. It would look rather stupid, in my opinion. Considering there's quite hot lava and liquid and solid iron-nickel core... :D

Title: Re: Celestial Objects Thread
Post by: Herra Tohtori on September 06, 2006, 09:28:43 am
...no, it is not.

It is a simplistic method and if you do like on the tutorial, you don't even get any water onto your planet, just differently coloured ground. IMO that's not (always) very realistic.

There are other glaring simplifications in the tutorial; mainly the cloud layer being practically misused to "create colour variation" to planet texture.

In my opinion, you should first create the actual surface - including colour variations, surface types and water and all the stuff like that, then put the actual clouds on top of that.

If you want to say that the pictures produced by following the tutorial as is resemble actual planets (refer to images of planets in Solar system), go ahead. I don't find them actually realistic, cool as they might look.

Read the first post  :P

Have you guys even read this link??? It's all about creating realistic textures for planets?????

Make a texture with that.  Map it to a sphere.  You'll find it doesn't work well.

Well, it *works* until you want to take a look at the poles. With the tutorial, there will be some nasty things going on around the poles.

I took a look at the other tutorial that Colonel Dekker linked to. First of all, it starts with some previously created texture. It's not something you can create from a scratch; you need the starting texture first, and it doesn't say anything about that.

Secondly, it seems to be made using something else than GIMP... perhaps a German Photoshop. It might give me some ideas, but I think I'll prefer to experiment on my own, trying to figure out things by myself.

Exactly.... and quite often, people place planets to the bottom left/right of the screen, or in the classic earth-from-moon style top hemsiphere over horizon (not sure why, seems to be a common aesthetic preference which I, admittedly, share) when rendering, etc.... not to mention the issue of symmetrical textures for wrapping it round. 

Also, I'd wager in general that planet textures will be higher resolution (which adds other concerns regarding detailing), as the nature of having an actual model usually hints at getting a bit closer to it than just the bitmap alone.

Surely it depends where, the texture meets though, Ditortion only really applies to the poles, Which are often in the case of M-class (i hate trek) are snowy, gas goants are normally uniform swirl, and rocky ones are just rocky.......


This is one to add to the K-Faq  once we master it..........

Well, try it.  It usually looks **** to have a uniform colouration in anything except snowy poles, and even in that case you have to face the issues of things like realistic atmospheric cloud, and that poles are not uniformly white in reality anyways (even if close to it).  With, say, Mars it's actually a struggle to keep the icecaps a reasonable and real size whilst cutting out the distortion..... hence why I (and probably others) would like to see a tutorial on such a thing.
Title: Re: Celestial Objects Thread
Post by: Herra Tohtori on September 06, 2006, 10:39:41 am
To create better poles, make the poles in texture one trasnparent. Then make another texture which has the pole textures on opposite sids of the equator and map that texture to sphere also; then turn that sphere 90 degrees so that the pole parts are visible through the transparent poles of the first sphere texture.

Blur the edges slightly or perform other necessary operations to blend the two parts together. Voilá.

...I know this is kinda duct tape solution, but it would work. It just takes some more work to do. And it is true that uniform colour poles suck, big time.

@ Herra, referring back to starfields and nebulae:

Ah, I didn't realize you were manually putting the big stars in.  I'd been too focused on using finding settings/tools to do it to think of that.  ;)
I used noise/hurl because it was the first decent-looking tool that I came across.  Works pretty much the same as default noise. 
Another cool thing to try with bright stars it to use the sparkle effect (under filters > light effects).  It can add some pretty nice eye candy to a starfield or small cluster of bright stars.

I've checked the guide Lt.Canonfodder posted, and (at least at a quick scim-through), looks very useful.  Some of the planets the author created are very impressive, too.  Definitely worth checking out. :)

Sometimes it's fastest and easiest to do things manually. For example, in GIMP I'm sometimes missing some standard MS Paint features, namely drawing lines.

ARgggh no, not them... :shaking:

 :lol:

I don't like them very much, they look cheesy to me. They might be useful if you want to simulate the light effects inside a camera or a telescope (ie. diffraction causing the familiar  four "spikes" of stars and so on, but I prefer to have the images as plain eye would see them. But whatever floats your boat. And I agree that in some situations, controlled use of any feature may get good results. :)

Yes... unfortunately that, too, requires some basic skills in editing existing textures. It doesn't tell you how to make a planet texture from scratch.

Mind you, pretty much no one makes planet textures from scratch. Real-world images and/or planet maps are always used as source material, and that's the key to making the planets look really good.

Theres a technique in Lightwave, which I'm assuming has a counterpart in Max, where you can apply a procedural texture to an onject and then bake that texture to a UV Map. If you create a map where most of the circle is Spherical Map, but the poles are planar mapped and then bake that texture you can get the map into a useable UV. The downside with this method is you need to be very good at procedural textures, and I'm not.

I also find a program like Deep Paint 3D is a big help for planets.
Title: Re: Celestial Objects Thread
Post by: Lt.Cannonfodder on September 07, 2006, 02:33:56 am
Problem with procedural textures is just that, they rarely look better than textures made by hand. They work fine in a few cases, but with planets... just no.
Title: Re: Celestial Objects Thread
Post by: Flipside on September 07, 2006, 02:43:47 am
Very true, however, they are useful for providing a template to work from, and for putting basic land-masses/shadowing onto your map. You can then, with work in Photoshop, work on the finished map using multiply layers etc and enhance the detail. At least that way you know you will get a smooth transition no matter where you look at the model from.

 :bump:


Some new stuff... Not as high resolution as the previous ones, but still looks nice in my opinion. Made from the scratch... mainly because I find it easier to make the texture myself from the beginning than to edit an existing texture. ::) I guess that's related to my way of climbing to a tree backwards. Meh. Again, the program used was GIMP, purely.


(http://users.tkk.fi/~lmiettun/Kuvat/Space/planet_1024.jpg)

Here's the same planet with settlement lights visible on the dark side. (http://users.tkk.fi/~lmiettun/Kuvat/Space/planet_with_lights_1024.jpg) That was just an experiment, though.


As I said, it's not as high-res as the previous monstrosities (such as the 4096x4096 pixel Mars). Main reason is that I made the original texture in 2048x2048 to save time. One GB of memory is on the verge of being inadequate for this kind of things, I've noticed. But I guess it could make a decent desktop in proper context.
Title: Re: Celestial Objects Thread
Post by: Aardwolf on December 03, 2006, 10:43:50 am
I think the settlements need less blurring. The distribution is fine, but they are too blurred.

Edit: idunno, maybe not.

Post by: Herra Tohtori on December 05, 2006, 03:47:13 pm
Another one, made with similar technique as the previous one but in 4096x4096 resolution. The difference is rather clear. Although I'm not completely happy with how the atmospheric blur came out on this one, this is perhaps the best of my planets thus far. :)

Post by: Herra Tohtori on March 28, 2007, 05:24:29 pm
It's time to bump this thread again, as people seem to be interested in planets again and threads about planets are popping up here and there. And of course, I've got some new planets I've made... :)

...Like this for example. Gas giant, and a habitable planet/moon orbiting it.

(http://i.imgur.com/KV6zPY3.png) (http://i.imgur.com/KV6zPY3.png)

Both are using entirely procedural textures.

Incidentally, I've been experimenting with ways to reduce the polar distortion on square textures. One important tool is the polar coordinates filter, which cannot be used outright but it does offer a way to make distortion-free polar areas out of a square texture. Sadly, it cannot really be applied to middle parts of the texture successfully, so it's a matter of making two polar areas and cutting the rest of the layer off, and then successfully merging unmodified part of the original texture in the middle with the polar regions up and below. Results can eventually be made into, for example, this (a low resolution version of the gas giant's texture - the original is 4096x4096):

(http://users.tkk.fi/~lmiettun/Kuvat/Space/gasgiant_texture_sample.jpg)

Or if you're making a habitable planet with continents and oceans, you can do the trick to a layer containging uniform noise clouds, then apply brightness/contrast to your liking, which gives you a nice outline texture for the continents. :)

(http://users.tkk.fi/~lmiettun/Kuvat/Space/continents_sample.gif)

This map can be mapped onto sphere without any distortion whatsoever. What you stuff into the continents is a different matter, obviously. And you can decide freely which is land, black or white... :cool:
Title: Re: Celestial Objects Thread
Post by: m2258734a on April 01, 2007, 04:09:01 pm
Your gas giant system looks great. How did you come about making the texture? What I do (which usually doesn't come out looking how I want it to) is that I apply the colors that I want for a gas giant using an airspray or any other similar pattern. Then, I motion blur the image until I get the desired bands. From there I add swirls and waves and so on and so forth. I then spherize the image and that's it. A very simplified description, but that's pretty much the gist of my "technique".
Title: Re: Celestial Objects Thread
Post by: Herra Tohtori on April 01, 2007, 05:02:51 pm
By using a complex combination of *several* layers.

The psd file where I've got the texture layers saved is round'bout 160 MB and has five layers at 4096*4096 res. That's medum-sized compared to some of the habitable planets, though... ::)

The polar coordinates distortion filter is extremely useful, and it was used to practically every layer. It's a tricky beast though... you have to make upper part, lower part and middle part of a layer and then blend them together as smoothly as you can, in order to make a texture that can be wrapped to a ball seamlessly. Now keep in mind that this must be done to every layer before blending them together to form the end result with different layer modes.

The base colour layer is basically an uniform noise cloud layer which has been polar distorted and coloured to my liking.

The belts and zones are made by making a 16*4096 layer, filling it with uniform noise, then maximizing contrast and applying motion blur horizontally to make the dark and light areas horizontal; then I copied the layer, turned it 180 degrees and superimposed it on top of the original to make the northern and southern hemispheres more similar... Then I simply scaled that layer to 4096*4096 and there I had the basic colour variations for belts and zones.

The turbulence was the trickiest part to get right by far.

First, there's two levels of turbulence. There's lower level turbulence that doesn't care about the belts and zones and runs beneath them as strong base currents. Then there's the finer detail closer to the surface, which is mostly visible at the edges of belts and zones as mixing colours, light and dark...

So, I first had to create lower level and higher level turbulence maps and polar distort them both.

Then I took the fine detail layer, put the belt/zone stripe layer on top of it and figured out how on earth I could make it most visible only at the edges of belts and zones... Then I remembered the way to find the edges on images. So I did some edge stuff to the stripe layer and in the end I had a new layer, which had black on the edge areas and white on the belts/zones themselves. Then I simply turned black to transparent and lo behold, the fine detail layer formed, which had most detail visible at the edge areas and less in the middle of the belts/zones.


Then it took some creative mixing of layer modes to make the end result you see... Feel free to experiment, it's not easy and takes a whole lot of time especially on the first time when you have to figure everything out, but it's definitely rewarding.


After the texture is ready, I just mapped it to sphere and checked that it was distortion-free. It was. :cool:


Also, some gas giants have very little detail visible to bare eye. Saturn for example only has mild belts and zones, but it has the rings... and a load of moons. Also Uranus and Neptune have remarkably little detail compared to for example Jupiter. The amount of detail is almost directly proportionate to the temperatures on the planet. High temperatures usually mean big energy differences wich cause violent turbulence. If the planet is more uniform temperature, much less detail forms. Different strengths of detail layers can be used to produce different kind of detail, obviously.


Also, a lot of system RAM is recommended for operating with big files. I got fed up with my HD cache scrunching like no tomorrow when the page file got filled (! and I had like several GB's paging file on settings!) and slowing everything down, so I walked to a store and bought two 1024 MB DDR memory modules to add to the two 512MB modules I had previously... so now my system has 3 GB of DDR memory. Unsurprizingly the HD pagefile crunching ended immediately, and now I can swap between layers and big files much faster and without fearing that the GIMP might crash because of some error in the paging process.

It took a cut on my wallet, but sometimes you just have to bear the hunger for art... :lol: I no longer wonder why graphics designers use such beastly computers as work stations. :rolleyes:

Nice planet Aardwolf.

I think you should go ahead and provide the original file. You don't have to save your image with the pure green background. You could just save your image as a 32-bit .tga by going through the process of setting your background to 0% opacity, depending on the program you used.

Herra, thanks for the tips on making gas giants. Seeing all of the fantastic pieces of work you all have made is making me realize something. There is so much talent on this thread, yet the planets of FS are in dire need of variety, higher resolution, and imagination. The planets used in the main FS2 campaign look great, don't get me wrong. They are marvelous improvements over the retail planets, but it gets frustrating when you see these planets being used in other campaigns in completely different systems. I have seen a red Venus-like planet, a red Jupiter, satellites Callisto and Europa with various colors, and Mars being used repeatedly. With all of the various campaigns that have been created, I think it would be nice to enhance the scenery and provide some variety with these planets.

Right now I am working on a set of 8+ planets for Warzone, and I am sure there are plenty of other campaigns which need some high resolution planets, whether they are low-orbit or high-orbit views. If it is all possible, I think it would be great if we could collaborate with one another and provide a form of package or .vp which includes plenty of high resolution planets that can be used for FS. It might be a slow project since making planets is not on everyone's high priority list, but I think it would be worth the wait. What do you all think?

OK here it is...

Speaking of high-orbit vs. low-orbit, this one is meant to be pretty big (in the game I designed it for, it is rendered as a square with the center 1.5 units away from the camera and with side length of 2 units). Other distances may make the curvature look wrong.

Yeah, I have also noticed that even though the current VP planets are a vast improvement over the original PCX images, they are still pretty much rip-offs from Solar system like you said. So perhaps it would be worth it to make a high-res original planets that would be used in retail campaign without need to change the missions - much like the retail star replacement effort. Perhaps it would be worth it to make it a joint endeavour?

Well, in the starting message...

(...)

Then I came here looking for a nice thread featuring planets and stuff, but I didn't really find one! All were like year or two old and had mostly dead links and some people who I've never before seen here, so I decided it was time to make a new topic for planetary art that HLP user pool spews at random intervals. I'll start with two of my planets I made yesterday and today.

(...)

So, what do you think? Also, feel free to post your own planetary creations and stuff. After all, I personally think there's a little too few planets around in Freespace...


<evil laughter> My master plan is starting to work! </evil laughter> :drevil:

 ;7


No, really, it would be great if we managed to create a diverse pool of planets from which campaign designers could choose planets fitting to their backgrounds, and if they didn't find one they liked, they could likely find someone to make tailored planet for their use, much like with Mandala Prime having two suns in the system, for example.

Well it sounds like a plan to me :yes:  I am all for it.

I was thinking... would it be better to move this thread into the FSU forum once we start getting more contributions, or should I move the "Stellar enhancements thread" in here since the term celestial objects refers to a broad range of stellar, substellar, and galactic bodies? Or should we do both?

Anyways, as far as recreating the original FS2 retail planets, I believe Lightspeed tackled the task already. But the Solar system planets really need to be redone. It's kind of annoying seeing these planets and satellites with different hues in various systems throughout the FS universe. Regardless, I would be more than glad to make this a joint endeavor.

there's a little too few planets around in Freespace...

Post by: Herra Tohtori on April 08, 2007, 12:31:25 pm
The islands' and continents' outlines look good to me, but the surface itself could do some more colour tones I think. Particularly the green looks like TMNT mutagen (or equivalent biohazard waste) spreading over the surface; forests generally reflect less light than plains so they would be darker. Water looks fine, but lighting could improve somewhat. If the star is behind the planet, there would be only a shallow crescent of the planet that well visible, unless there's another star in the system (which is of course possible).

As for what comes to background and the star... I'll keep it diplomatic and say that I wouldn't make them like that. ;) I prefer my space dark and nebulas subtle... And I think the lens flare effect looks kinda cheesy, but that's just me...


What did you use to make the planet?


->Mad Cat: Thanks for the link, I'll check it out as soon as I'm back home to my own beloved PC. I'll have to convert the instructions to GIMP-jargon though...curse the way they use different terminology in different image editing programs. :nervous: I won't even try any of this stuff with my parents' PC with only 512 MB RAM (my own now has 3072 MB RAM...

Title: Re: Celestial Objects Thread
Post by: Sypher on April 08, 2007, 02:20:02 pm
Thanks for the input

Planet was made with GIMP (to get the water I basically duplicated the still-gray-scale surface layer, inverted the color, messed around with brightness and contrast (extreme contrast, low brightness), blurred it a tad, Changed black to alpha, used colorize on the layer then mapped it to the sphere with the exactly same settings as used while mapping the surface layer)

Anyways, I personally think that my second try turned out far better, though I aimed for an even more expressionistic style of Nebulae, and I am not happy with the moon (Gotta get more experience with those). Whatever, ...

The basic idea was to paint the ring as doughnut (meaning Circle interrupted by smaller circle), subtracting some random noise for it (for alphaness) then mapping it to a plane (play around with the rotation).

Your nebulae look awesome. They have a very artistic feel to them. Would you mind telling us how you created them?

>thesizzler
Have you found a good technique for creating rings? I would just recommend experimenting with all of the features of whatever program you are using until you get what you want. I have been experimenting with The GIMP as of lately and I find it to be a very good substitute for PhotoShop. BTW, the shadow you produced on your planet seems more like an eclipse shadow. The concavity of your shadow needs to be inverted, unless of course there is another planetary body or large satellite producing the shadow.

I am currently making my second planet for Warzone. Terran1 was designed to be a realistic replacement for the low resolution version, but this one is a little different. The low rez version of Lava1 actually looks like lava. Given the size of the planet in-game, and how large the lava texture appears on the planet's surface, I found this to appear unrealistic. Such planetary features would not be so distinguishable, so I tried to make the lava planet more like the hot super Earth extrasolar planets that have been discovered in close proximity to their parent star.

Well, as I mentioned in the other thread.  I figured the lava "planet" to be a moon, not a full scale planet for the very reason that one wouldn't be able to see such features on a proper planet.

This is great stuff.  We'll want to inventory the different systems found in Warzone and see how many of what kind of planets we can use.  This planet is certainly better than any of the standard stock planets.

For the lava world, what do you think about altering it to be only half lit.  The dark side would then be lit only by the glowing lava,which would make for quite an interesting effect.

Sure, I'll make the lava planet half lit. Do you want the illumination to divide the planet in half completely, or do you want there to be some waning or waxing? Also, when should we start looking through the systems in Warzone for the number and types of planets we can use?
Title: Re: Celestial Objects Thread
Post by: Admiral Nelson on April 16, 2007, 09:48:32 pm
Well, I think that there should be enough unlit to make the lava stand out, so roughly half is probably good.

I'll go thru the missions and see which stock and custom planets were used where to see what we can use.

Post by: Herra Tohtori on April 17, 2007, 12:28:03 am
Aye, the lava planet looks good, but the lava must be really bright to be clearly visible under daylight area.

Might be wort experimenting what it would look like if you made just a shallow crescent of the planet lit by direct sunlight, and make the lava emission spread onto the atmosphere and dimly lit the shadow side with both the atmo and the lava glow.

I've been struggling with HD mishaps... long story short, had everything backed up and wanted to re-install Windows for reasons unimportant here, but the recovery tool decided that it liked the backup drive more and formatted it, and installed Windows on that HD... didn't lose anything *really* important, just almost all my downloads which were on the other HD along with the backups of the primary partition of the OS HD... :sigh:


Also, practically everything put here lately looks rather fine. :) I've been experimenting with methods of making a texture with craters so that they appear round all the way to the poles. Found a way, too, but haven't had the chance to actually use it to make crater-filled planet surfaces... it involves making differently sized round brushmarks on the texture at more or less random intervals, then using an edge filter of choice to make out the round edge mountains of the craters, then apply polar distortion filter to spherize the texture... it results in practically zero (or damn close to it) polar distortion when the image is wrapped on a sphere later, but it means you'll likely need to clean up the equator a bit to make the two halves fit together - that can be pretty nasty sometimes.

Ugh, I need to look at the places I post in more regularly. Anahoo.

M22, you asked me how I do my nebulae, and to be quite honest its rediculously simple in theory but a bit tedious in practice.

I start with a black BG and a lense flare for a light source, then I take a random oval, and wave filter filter it a couple times, randomizing it untill it looks somewhat natural. I then duplicate the layer for future referance, and give it a white outline. This outline gets darkened later for colouring, and potetially has peices erased if something overlaps. I continue to repeat this process untill I have something I like, then I go onto the colouring and lighting.  Then I may or may not add a star field and some other optional eye candy, and finally, I attack it with the dodge, burn, and smudge tools to atain fancy looking details.

And for some more stuff for you too look at.

Let's necro this thread again... it seems to bring up more planets after every necro, so I don't see any reason to let it sink to oblivion... :p

Especially as I've been trying out some new things. Like mountain ranges that would look a bit more realistic than bumpmapped blobs of diffuse noise. Sooo... Came up with this. No rivers in it as of now, will likely be added at some point in the future, but for now I wanted to concentrate on the mountain ranges.

(http://i27.tinypic.com/2zdsny1.png)

The scale of the mountains is somewhat off, though - but let's just say those are some bigass mountains on a moderately sized habitable moon and be done with it.  :p

Making the mountain ranges manually with 3x3 fuzzy brush and adding another level of fractality would likely end up in more realistic mountains, but would take inordinate amount of time. Does anyone know how to make kinda thunderbolt-style patterns procedurally with some filter/combination of filters? I obviously checked the GIMP's fractal stuff first, but the lighting fractal available in the list was kinda too simple for my purposes... :blah:

The mountains are a bit too regular and there's no terrain lighting/shadow; mountains should be darker on the side facing away from the sun, etc.

Nice spec-reflec on the water tho :D
Title: Re: Celestial Objects Thread
Post by: Herra Tohtori on February 13, 2008, 12:33:58 pm
Actually, they do have lighting. That whole effect is the result of the terrain being bumpmapped. The resize to 1024x1024 just takes some of the effect away. Here's a bigger one... (http://www.mediafire.com/?24e2avcxlzz)

However, the problem is more about program limitations than whether or not I want to apply bumpmapping to it. GIMP can sufficiently map a texture to a sphere, but bumping the sphere's surface is a bit too much for it. And, as the sun shines from different angles at different locations of the surface, I need to either manually bumpmap each visible region differently depending on how I guesstimate the sun light coming from; OR I can use an uniform moderate bump mapping applied to the whole texture. Which I did there.

For example, mountains near zenith are pretty much equally bright on both sides. Mountains near the terminator have much more difference on the lighting of the slopes - but that also depends on the angles of the slopes.


Perhaps I should just go and render it on some 3D program that can apply bumpmaps to objects, but there's something pretty cool about doing everything in GIMP from the beginning to end... :p

Ah, now I see it; still, the high parts seem too narrow.

That's because these mountain ranges are relatively simple, as well as the scale is way off like I said. The peak ridge itself actually is very narrow in most mountain ranges, but there are many many more of them than I have in this planet. If the scale were correct, these would need to be resized to about 1/10th of their size, and then copy-paste parts of them next to each other to cover the same area...

Trying to do something to increase the selection of not only planets, but also different phases of them.

planetg-<phase>.*

(http://i32.tinypic.com/iwp448.png)


I'll try to find time to make similar high quality versions of planets/moons that would resemble the retail/current mediaVP planets (planetA-F)... to be honest, despite being a major improvement compared to the retail planets, the mediaVP ones aren't that good either (no offense to the makers). We'll see where this takes me... :shaking:

Title: Re: Celestial Objects Thread
Post by: Herra Tohtori on February 26, 2008, 08:30:15 am
I think Nelson would know better than me, so I'll quote you and myself for clarity...

Idea> instead of drawing up new phases for each planet, why not make a selection of masks to put over them in the background editor? :nervous: If it's feasible. Either the same colour as the default starfield.pof textured or some kind of freaky alpha map using SCPower to "erase/hide" a portion of the image file using layering maybe? :nervousagain: ;)

Assuming you can stack planet textures on top of each other and that it works well too. I don't know if that's even possible, but assuming it is...

I thought of that as well, but the problem is that in a full-lit version you would have the atmosphere surrounding the whole planet with a rather prominent glow. Now, if you would stack a shadow mask over it, you would need to stretch the shadow mask over the atmospheric glow of the underlying fully lit planet.

This would undoubtedly work pretty well, as long as the background doesn't have any nebulae on it. If it had any nebula behind the planet, the stretched shadow layer would visibly show up against the nebula, or at the very least it would be visibly larger than the lit side of the planet.

A possible solution would be to use a base texture of the planet without any atmospheric glow whatsoever, and overlay that with appropriate shadow/atmo-glow hybrid layer. But that would require the mission designer to stack the two planets on the correct positions, then rotate the shadow/glow layer to correct position, and on the user end it would end up using twice as much VRAM as simple baked-in shadow/glow planet image would. I have no idea how much of the actual rendering performance goes to the background and how much the performance would be hit, but every unnecessary bit is too much in my opinion...

Another thing is that with some planets (especially those that are on skybox use and thus are very high resolution) the direction from which the light supposedly comes from can pronounce terrain elevation (mountains) and it could look fairly stupid to have mountains on the surface of a planet and notice that they look more like canyons judging by the supposed lighting. :p


That said, I need some opinions.

This is the retail planeta1.pcx:

(http://i31.tinypic.com/15q91xl.png)


What I need is opinion on whether this is supposed to be a water-covered planet with clouds on the atmosphere, OR an Uranus/Neptune-like mostly featureless gas giant?

I think it's supposed to be an oceanic planet/moon, for three reasons. One, it has a reflection, which points to clearly defined interface between shiny (liquid) surface and atmosphere. Gas giants just have clouds all over with respectable amount of albedo, but they don't produce glints or reflections like the surface of liquid or ice. Two, it has a very thick atmosphere in relation to the planet's diameter; gas giants don't really have visible atmo glows from the distance it takes to fit it onto the field of view entirely. Or, well, they do, but it's thickness is lost in the relative diameter of the planet, and doesn't even reach one pixel on these shots so it's not worth the trouble to get into them.

Three, the clouds seem much more like the ones on Earth than the ones seen on gas giants (though that's mostly just my edumacated opinion, but still).

Fourth point wold be the combination of reflection and the fact that the reflection is blue, which means that the atmosphere scatters blue light in very similar way as Earth's atmosphere does (since water itself is almost colourless, it's blue on Earth only because the atmosphere happens to scatter blue light the most and absorb other wavelengths more). On a cloudy day, water is grey...


I know that in current MediaVP's it's more like a gas giant, but I think that's a bit of a mistake... I personally am an advocate of a water planet (since the retail seems to point to that direction in my opinion), but I understand if people used to MediaVP interpretation would want to keep it more like gas giant.

So, I'm open to opinions. :)


EDIT: Here's a water planet as a possible replacement for planeta1, complete with five phases.

That would take care of the lighting and shadow - the only problematic area I see is the air coronas. Putting them into the skybox would also solve the scaling issues and make them render after everything else.

It wouldn't take care of shadow as FSO has no shadows (yet).  Only lighting.  Atmosphere could be a problem, but there's also the fact that unless you make the model really high-poly, it is easy to see the edges and know that it is not round (just look at the Earth model from inferno in the last mission :rolleyes: ).  There's also the fact that with a skybox, you couldn't scale the planet and you would be stuck with whatever size it was.

There are several issues with using models as planets. Here are what I can think of...

1. Resource intesity. To look good, planets need BIG textures. Practical aesthetic minimum is 4096x2048 sized texture. However, many non-recent cards (as I've come to notice) don't support textures this big, and only go up to 2048 pixels as maximum width and/or height of the texture. With ready planet images, a 2048x2048 sized planet has HUGE amounts of detail and usually 1024x1024 sized planets are more than enough. And look better than models.

2. Need to use anti-aliasing to get non-jagged planets. Sucks for those who get a slideshow with any kind of anti-aliasing... With readily baked background images of the planets, this is not a problem at all.

2. Lack of advanced lighting effects like volumetric/shaded atmosphere layer result in visually less stunning end result than planet background images, in which you can bake the effects in with varying amount of accuracy - depending on whether you use renders or purely photoshopped/GIMPed planets. Renders have more realism, but for some reason I prefer doing my planets in GIMP from the beginning to the end... I've done some experimenting with adding an "atmosphere layer" above the ground, with very limited success... it makes the planet flicker from long distances and doesn't look too stunning from nearby.

3. Same applies to clouds. You have two options with clouds - either use another model layer above the ground level to house the clouds (which ends up problematic from long distances) or bake them onto the terrain texture. Neither method ends up looking spectacular, and usually the clouds look flat no matter what you do... normal/height maps might help in this, though, but I haven't tried that. :shaking:

4. Shadows are not really that big of an issue, since the model itself is most likely just a sphere, if you don't want to go absolutely nuts with polycount and planetary detail. If you want to have mountains, normal maps can take care of them... but the level of detail you can achieve is rather limited anyway. Talking about polycount, the planet doesn't need to be ultra-high-poly model. Properly done smoothing is way more important. About the only way you can notice the polygon seams is when you go looking at the speculars from small distance.

5. Size. Correctly sized planets just don't seem to work in FS2_Open, or at least with my model conversion skills... also, realistic distances are problematic and end up with flickering planets and stuff. And miniature planets look a bit stupid IMHO, and can't be considered any more realistic than background images.

The modeled planets do have some benefits, though mostly only with objects that have no visible atmospheric glow. Gas giants and their rings work spectacularly well (if you ignore their ridiculously small size), speculars and lighting are somewhat more accurate than with bacground planets - or rather, with model planets the mission designer does not need to think of the planet lighting issues like having the lit side of the background pointing at the sun with roundabout correct angle - and since you can move around the planet, you can see it in more phases than just the one offered by background images.

Mostly, though, the cons win the pro's in this case. At least for the time being. :blah:


Here are some screenies... most from Cardinal Spear, although the atmosphere/normalmap test doesnt' belong there.

Thanks for clearing that up Herra!

It does have promise, but it isn't up to reproducing the same detail a background image can store.
However I think, some sort of hybrid would be needed for low-orbit situations.

Namely, in BTRL when you're close to the planet and have this huge bitmap below you - the lack of geometry and the rendering distortions when you change your bearing inevitably give it away, and it looks - FLAT.

Any idea how one could combine both techniques (high quality pre-baked bitmaps and models) into a good low-orbit planet?

The modeled planet would look just as flat for the most of time... you can count how long it would take at 200 m/s to change the view point sufficiently for the planet's appearance to change notably (200 m/s = 720 km/h, whoop de doo...). In fact, a model would appear even more flat because you wouldn't be able to cram as much detail (cloud shadows, terrain elevation effects on lighting etc.) onto the model... without inordinate amount of time, or autogen script for planets, and quite frankly there are a few more important things to use the resources on IMHO...

Besides, effectively the only difference you could see would be rotation of the planet, since FreeSpace_Open doesn't (yet!) support orbital mechanics and if it would it would be a nightmare to fly... if you want to try that, load and install Orbiter, start a scenario docked with ISS, then head a dozen klicks away and try docking with the station again... then try to think what it would be like to try and actually hit enemies with primary weapons. :p

Also, if the (habitable-looking) planets are anything like Earth, it would have ~20-30 hour rotation time - not exactly what you would notice very much in a typical mission completion time in FS2/BtRL... in half an hour, Earth rotates a whopping 7.5 degrees.

It would be almost like demanding that the grass needs to grow in a first person shooter game for it to be realistic. No one will spend time watching the grass grow... or planet to rotate. And since orbital mechanics will hardly appear in the game any time soon, if ever, that's the only change you would be able to see anyway.

Any idea how one could combine both techniques (high quality pre-baked bitmaps and models) into a good low-orbit planet?


No, but in this case, pursuing realism is not worth the advantages. If you're a physics accuracist like me, you'll just have to ignore the fact that there are no orbits or gravity in FS2_Open. :p

Let's just go with what looks cool, right.

Thanks for clearing that up Herra!

It does have promise, but it isn't up to reproducing the same detail a background image can store.
However I think, some sort of hybrid would be needed for low-orbit situations.

Namely, in BTRL when you're close to the planet and have this huge bitmap below you - the lack of geometry and the rendering distortions when you change your bearing inevitably give it away, and it looks - FLAT.

The modeled planet would look just as flat for the most of time... you can count how long it would take at 200 m/s to change the view point sufficiently for the planet's appearance to change notably (200 m/s = 720 km/h, whoop de doo...). In fact, a model would appear even more flat because you wouldn't be able to cram as much detail (cloud shadows, terrain elevation effects on lighting etc.) onto the model... without inordinate amount of time, or autogen script for planets, and quite frankly there are a few more important things to use the resources on IMHO...

Besides, effectively the only difference you could see would be rotation of the planet, since FreeSpace_Open doesn't (yet!) support orbital mechanics and if it would it would be a nightmare to fly... if you want to try that, load and install Orbiter, start a scenario docked with ISS, then head a dozen klicks away and try docking with the station again... then try to think what it would be like to try and actually hit enemies with primary weapons. :p

No I'm not talking about a moving / rotating / orbited planet.
Just a static mesh.
What I'm talking about, is that close to the planet, you can no longer accurately depict it with a single bitmap. When I said flat, I wasn't talking about the planet's surface - you still too high to notice that. What I talked about was the way this bitmap is transformed / distorted when you look at it from an angle. It's a giant plane in space, not a globulus planet.

Maybe you don't even need a model, but a tricked out bitmap, that's too big to fit into your field of view, and therefore on the edges you can do tricks by already incorporating the 'curveous' effects of the horizon.

Now that I imagined that, I know what the problem is: when you look at planet bitmaps from an angle, you see an almost straight edge. Instead you should be seeing an arc. I can't make what I mean any clearer.

Moons are generally added as additional bitmaps in the mission; this method adds more versatility.  I'd say make the moons their own bitmaps.

Post by: Herra Tohtori on March 27, 2008, 10:04:21 pm
That isn't as unlikely as you might think... the atmosphere can have lighting effects of it's own, not to mention it's ability to diffract and bend light. It doesn't look too unrealistic to me, especially considering the phase of that planet.

As to my own stuff, I'm working on it kinda sporadically. The version of GIMP I had before this was very *****y with high memory usage and kept giving me GLib memory errors and crashing at most inopportune moments and saving after every process got frustrating and I let the planets rest for a while, then went to spend the Easter at my parents' and came back day before yesterday... Haven't tried the latest version of GIMP with high stress conditions yet, I'm hoping it'll be stabler.

I'm hoping to get all the retail planets done in new form before the new MediaVP's are ready so I could make one package of them and send to DaBrain. I'll probably then upload all the rest of the phases of the new retail planet versions, and possibly other stuff as well, as a planet repository for mission/campaign/background designers to use.

Yeah Blowfish, I know... same thing as the last one

I'll get this one fixed as-well and release to everybody though.  The white line is because of semi-transparent black pixels when converted to a tga - tga flattens everything on a white background so...

anyway, I will have this one up shortly

Post by: Herra Tohtori on March 28, 2008, 07:12:48 pm
Hmm... try adding some slightly blurred noise to the cloud layer to add pseudo-detail? Or perhaps add it to the displacement/normal map instead. The clouds do look a little detail-less... What resolution is the texture by the way? Other than that, it looks pretty good IMO.

Though, you should set the number of retail stars to zero if you use a skybox, they look ridiculous when they shine through the planet. But that's not related to the planet...
Title: Re: Celestial Objects Thread

Title: Re: Celestial Objects Thread
Post by: Aardwolf on March 28, 2008, 08:07:03 pm
The thing is, even though you used a displacement map, the inside of the hurricanes and other such areas of cloud are all solid color, with no variation. Cloud tops aren't flat in areas like that. Make them bumpier there.

And it's been a while but I've gotten back into the planet-making.  Here's what I've got so far on a terrestrial world.  I think the clouds still need some work, and I'm debating trying an actual cloudmap.  Any thoughts?

I'm bumping the thread again to discuss methods of making lava-planets.

I've done some experimenting and I think I've found a way to make a sort of "glow" effect for lava emission on the darkside of a planet.  In the example below I set the surface layer mode to "lighten only" and the shadow layer to "grain merge". This seems to allow only the brightest parts of the surface texture (the lava) to shine through the shadow layer; the rest is darkened.  Note this works best (IMO) with surface textures that have sharp variations in brightness/contrast. Those made with plasma-cloud rendering probably won't work as well.  For this I used a picture of red marble with white veins.

Also here's a quick and easy way to find the right places to put a shadow layer:  Take a piece of paper, and place one of the corners on the edge of the planet.  Then the points where the edges of the paper meet the edge of the planet will always define opposite sides (180 degrees aprart) of the planet.  Any portion of a circle that passes through those points is a viable terminator line for the shadow. :)

Draw an arc so that it crosses with the sphere of the planet. The line from the crossing points to another should divide the planet's disk into half.

Better yet, make a surface texture, map it onto a sphere and let the lighting from the light source deal with the shadow stuff; that way it's easier to get the shadow line correct and natural looking. This can be done in either GIMP or a 3D software of your choice.

If seriously, if the GTVA looked at the Ancient homeworld from some far away system using a telescope or something, and they'd see it clearly, the view they'd see would be from a long time ago. Depending on the distance.

EDIT:

It is my sad duty to report, that this planet will not be used on a skybox, or as the Ancient homeworld. Either I converted it badly, or something else, but it looks bad on the skybox ( low quality ). I might use it as a background bitmap for certain missions, or as a moon to the Ancient homeworld, unless FreeSpaceFreak minds.

The surface water on VPrime is undrinkable even by Vasudan standards, water's most likely found underground, or possibly synthetically manufactured/filtered.

It doesn't look Vasudan enough. Anyhow, it says: Vasudans originate on the fourth planet of the Vasuda system, the only planet in that system that is capable of supporting life. Known as Vasuda Prime, is a relatively hostile world. Both of the twin continents of Vasuda Prime are almost entirely desert, and most of the above-ground water is, even by Vasudan standards, undrinkable. In order to adapt to these surroundings, Vasudans developed quite rapidly.

So I'd say FSFreak's depiction is relatively accurate. But I'd like to see at least 1 version with crappy water.

The clouds shouldn't be beige, anyway. But if you make the ocean just one smooth sheet, it will look much different from the textured ground. A different shade of beige would work too.

That Vasuda Prime looks awesome. It's just how I imagined it to look. Maybe a bit different atmosphere glow, but good nevertheless.

As for the second one. One slight grammar mistake in the text ( 'it's' not 'its' ), and 10 bilion Vasudans were killed and Vasuda Prime became mostly uninhabitable. Also, the line on Vasuda Prime showing it's ( forgot the word ) needs to be fixed. On the other hand, it also looks great.

You all have been producing outstanding pieces of artwork. Just a quick thanks from me for everyone's contribution. FreeSpaceFreak, your Vasuda Prime looks great. What program did you use to construct the planet's parent star in your image?

I have been working on a new planet for about 20 hours now, so I'll see if I can post a preview later on tonight.

EDIT:

(https://webspace.utexas.edu/maa945/FSSCP/FS2.jpg)

This planet is actually a render from 3ds Max. It has a radius of 6228.71 km, as scaled in the program (for those who are interested in knowing the dimensions). The planet found in the FS2 intro was a primary inspiration for this render. Compared to the other planets I have done, I would have to say this one is far more subtle in terms of color, even more so than the planet seen in the intro. I am content with the planet as it is, but if you all believe I should increase the saturation in order to make it look more like the planet in the cutscene, I'll make the changes and provide an update over the weekend.
Title: Re: Celestial Objects Thread
Post by: Herra Tohtori on June 11, 2008, 03:55:56 am
Actually saturation looks nice, not all rock planets' atmospheres scatter blue like Earth's. But is it possible to move the cloud layer to an invisible sphere a bit higher than the ground texture, then make that cast a shadow to the surface? What about normal/bump maps, especially for cloud layer? In a 3D renderer it would be a lot easier to make lighting accurate for terrain elevations, so I would definitely be using that... AS it is, it looks a bit "flat".

On GIMP, I usually duplicate the cloud layer(s), then invert colours on the lower one, increase the size one or two per cent on the higher, and the reduce the opacity of the lower one with suitable layer mode so that it looks like a shadow from the clouds cast onto the surface. Then I might move the shadowing layer to some direction a few pixels if the lighting comes from sides or up or down... And I also usually bump the cloud layer at least once based on itself, which makes it gain some pseudo-depth in itself.

It looks good anyway.

No sphere designer... Make a square planet texture and map it to sphere (Map to object). Lighting takes care of terminator automatically that way.

Better yet, make two separate textures for ground and water... then set reflections to zero for ground and suitable amount for water. You're gonna need to play around with transparency stuff in layers to get it work right though.

@Retsof: That's not bad for a start. I would say: learn to properly use layer masks, that way you can get this to look right without merging all the layers before you map it. Here's a tip: you can't map masks to sphere, but you can copy-paste them to a layer, map it to sphere and copy-paste it back into the mask again.

I... seriously doubt that you're using that kind of resolution. :p

If Earth has a circumference of about 40,000 km, and you're using a 8192x4096 resolution texture, one pixel at equator equals to about... 5 km detail on the surface. 4096x2048 res texture could have 10 km per pixel on the equator; that's the resolution I use for my GIMPed planets. Even if the planet was quarter the size of Earth in diameter, it would still have equatorial circumference of about 10,000 km, and a 8192x4096 res texture would have about 1.2 km/pixel detail level; 4096x2048 would have 2.4 km/pixel.

Unless the program is using procedural shaders for the surface, there's no way the texture could be of that detail - it would probably fill a good sized room full of HD's at that detail level. For earth sized planet, the texture size should be about 400,000,000x200,000,000 resolution - the closest powers of two resolution would be 2^29x2^28 (536,870,912x268,435,456); at 24 bits per pixel, that corresponds to 3.45876451*10^18 bits, which is, according to Google, 393 216 terabytes... if you had one terabyte HD's, that amount would be in a grid of HD's that was 73x73x73 HD's per side, plus the odd 4199 HD's. That's a lot of data storage... ;7


Perhaps 10 km was what you meant... instead of centimetres...? :nervous:

Regardless, it looks rather cool. Also, for rendering you might want to try some free 3D software like Blender - you already have the textures if I'm not much mistaken,

So, I downloaded GIMP and gave a try to this planet-making business. Unfortunately, gimptalk.com seems to be down, so I couldn't get my hands on any relevant tutorials. So I was left on my own to discover all the tools. But that's not my biggest problem with planet making yet. It's about getting my atmosphere right.

My first planet looks like this:

(http://www.penguinbomb.com/ithov/Planet1-v1.jpg)

I tried Herra's way (posted on the 1st page), but for some odd reason it doesn't work. Either I did something wrong, or simply misunderstood something. I did the following: Drew a black background with the Bucket Tool, and assigned it to Layer 1. Draw the planet (no clouds; Layer 2). Did the third layer: a gray circle 10pxs thicker than the planet's surface, set its opacity to 82%, and pulled it one level down in the layer hierarchy to be below the surface layer. What have I done wrong?

Well, the clouds are weird, too. If you can give me some advice on making clouds, please do so.

Thanks.

[EDIT]I found a tutorial. It works. The clouds are gone, because I forgot to make that layer visible when saving. I don't really mind. Look:

Not bad at all. The atmosphere in the second one is a bit too thick however, it should be more like in the first one.

And yes, creating good clouds is (IMO) the most difficult part of planet-making. Personally, I use layer masks, but I'd recommend you to experiment and find a way yourself. That way you'll get to know the GIMP better. Oh, and do some of these (http://www.gimp.org/tutorials/) tutorials as well: especially the two floating logos have helped me a lot.

I basically make textures for planets but haven't learned to use a full fledged 3D rendering program to utilize them to fullest, so I use GIMP's map to object (sphere) function and let that take care of shadows and lighting... for the most part. Getting aquainted with some rendering program is on my to-do list... probably Blender.

Clouds... make some Plasma, greyscale, then IWarp and adjust brightness/contrast with good taste to create swirly and stretched and different cloud patterns. I can post some shots of the phases later today. Perhaps. If I can bother. :nervous: Also, Polar Distortion function is very great in making textures that don't have any polar distortion when mapped to sphere, but getting it to work correctly is a bit time-consuming since fitting the northern and southern part of the polar distorted texture together is not very easy and requires some creative thought...

Only 2 things are needed until it's perfect:

1. Have the part around the lava more orange/brown/burned.
2. The lava cracks should end in small lines, not the wide ones like now.

Yes, but that doesn't tell me how to create the sort of thing I need. More precisely, craters. GIMP's crater-creator filter is adequate for making the general surface, but I would like to place some visible, deep craters.

As to feedback your planet: The lava part looks decent enough. I wouldn't say "perfect," because then I would run out of adjectives if you show something better. :D But I suggest spending some time on the grassy part. Add some rivers or lakes, or mountains.

Allright, here (http://www.mediafire.com/?teejvtchu1y) it is. All planets in this post (http://www.hard-light.net/forums/index.php/topic,41939.msg1104677.html#msg1104677), the damaged one and a slightly improved version of VPrime, all in 2048 x 2048 .png format - about 14MB compressed, and about 14MB uncompressed? Is that me or is it 7-zip?

Anyway, a picture of the final version and the VPrime:

the lava filter doesn't make good lava, imo. I make some solid noise and blur it.

Yeah, I'm not too fond of GIMP's lava filter, at least not for actually making a lava-like texture.  I like manipulating photographs to get the specific look I'm after.  Solid noise works pretty well, too.  Also try using the emboss distortion tool under filters, it makes a rather nice effect.

Title: Re: Celestial Objects Thread
Post by: Herra Tohtori on August 19, 2008, 03:18:50 pm
I'm wondering how you all get "map to sphere" to work without horible stretching.  :doubt:

Two factors.

First, work in very high resolution - 4096^2 at least if you can manage it, and then you can scale down the end result if there's too much stretching to your tastes. Also, don't make the sphere fill the whole layer (distance 0.9) - keeping the sphere at default distance tends to reduce surface stretching notably. Of course the distance kinda also depends on whether you're making a skybox texture or a distant planet background image...


Secondly, to avoid polar distortions in the mapping process itself, you can negate them almost completely by applying Polar co-ordinate distortion to the texture's northern and southern hemispheric part and then blending them together with the unstretched equatorial area.

For example, a simple continental outline map could look like this (in 4096^2, of course):

(http://users.tkk.fi/~lmiettun/Kuvat/Space/continents_sample.gif)

Same technique applied in multiple layers to make a gas giant texture:

(http://users.tkk.fi/~lmiettun/Kuvat/Space/gasgiant_texture_sample.jpg)


It takes some practice and manual labour to get the parts of the map to match, but in the end it isn't as complicated as one might think, but when you get it down, you can make pretty good spherically mappable textures with minimal distortion.


Also, you can cheat your way around polar issues by using large polar ice caps, but, well, if the planet is not supposed to have them you're kinda screwed. :p
Title: Re: Celestial Objects Thread
Post by: watsisname on August 20, 2008, 12:46:32 am
How exactly did you do your nightside lava? It looks way better than my crap.
To make the night-side emission I up the contrast a bit on the surface texture, and set the shadow layer to overlay, which increases the contrast further.  Doing this makes the lightside look pretty crappy, so I fix that by adding new layers over it for color, saturation, and contrast correction.  If you'd like I can send you the .xcf file so you can see exactly how that works.

I'm wondering how you all get "map to sphere" to work without horible stretching.  :doubt:
There's several ways of doing this, some are pretty sneaky.  In addition to Herra's methods, you can use the "make seamless" tool to fix the edges, but you'll still have polar distortion.  In my case I didn't make it seamless, but instead rotated the sphere so the seam is out of view.  Then I paint some dark areas over the nightside which also help mask the polar distortion. :)

Just for kicks - try and duplicate the cloud layer on that planet, then reduce the size of the lower layer by perhaps 0.2-0.5% (finding a good value is determined by testing); then use that layer to act as shadows cast to the surface of the planet, darkening the surface under the clouds. It creates a pretty convincing effect of the clouds having altitude without much of fancy tricks by lighting. And it looks off, move it a pixel or few to some direction depending on where the light is coming from. :)

Also you could try bumpmapping the cloud layer with itself, it tends to add some depth to the clouds in my opinion. It's only noticeable in high resolution, but IMHO it's worth it anyway.
Title: Re: Celestial Objects Thread
Post by: FreeSpaceFreak on September 22, 2008, 11:24:31 am
@Retsof: Thanks ;)

@Herra: I did the shadow layer and the bumpmapping, but somehow they have no noticeable effect. I probably pulled up reflectivity and intensity too much for mapping, I think I'll redo the whole cloud layer.
Also, what do you mean by "it looks off"? (The light is coming straight from the left here, dunno if that's got to do with it)
Title: Re: Celestial Objects Thread
Post by: Herra Tohtori on September 22, 2008, 12:19:26 pm
Also, what do you mean by "it looks off"? (The light is coming straight from the left here, dunno if that's got to do with it)

I mean that when you just put the clouds' shadows to the surface of the planet, they are directly "under" the clouds themselves. If the light comes from left, moving the shadow layer a few pixels to the right could make a difference regarding the perceived altitude and direction of the shadow of the cloud. In some occasions the shadows could look off without this adjustment; sometimes not. It's pretty much case-by-case basis to get it look good.

This is a good sample of how the clouds look on high resolution; the planet is BrandX's Corellia and it's originally lower resolution, so the planet might look a bit off, but it's still a good showing of the clouds themselves:

Wow, that's beautiful.  The surface texture is top-notch. :)
Regarding clouds though, maybe it's my personal preference but I don't feel they should be brighter than icecaps.  (If we are dealing with water-clouds and water-ice, anyway).  Taking earth for example, the albedo of clouds compared to ice is actually very close:
http://www.endeavours.org/sec/main_images/fullsize/apollo17_earth.jpg (http://www.endeavours.org/sec/main_images/fullsize/apollo17_earth.jpg)

Regarding old Marsy, I've made some considerable changes to it, especially with the surface.  It's a very powerful technique, I think, to add several different layers with various modes together to make one surface texture.

@Herra Tohtori:

Thanks for the tips. When I was talking about saturation, I was not referring to the color of the planet's atmosphere. That is primarily effected by the effective temperature of the parent star and the composition and density of the planet's atmosphere. I was referring to the saturation of the surface texture. Take a look at any image of Earth taken from space and you won't see neon green vegetation. I know this slightly deviates from canon, but I wanted to make something convincing and subtle. Obviously the planet I'm working on is not Earth, but I wanted to make it Earth-like... with a thicker atmosphere with higher concentrations of methane and airborne chlorophyll.

I also had the clouds on a separate mesh, but I forgot to increase its height. The bump map is also present, but the image of the last version of the planet was taken at a far distance from its surface. Such details like mountainous terrain would not be distinguishable from these large distances. Take a look here for instance: http://www.endeavours.org/sec/main_images/fullsize/apollo17_earth.jpg
 (http://www.endeavours.org/sec/main_images/fullsize/apollo17_earth.jpg) However, I have to admit that the bump and surface texture are horrible as they are. I still have much to do to improve the appearance of this planet, but here you can see how far I have gotten:

The planet itself is actually made by BrandX; I only did the clouds (which I did mention but probably should've emphasized...) and posted the image pretty much because it was the best example that I could find that used the cloud shadowing thing I mentioned... And the planet is, AFAIK, actually drawn and not a texture mapped to sphere.


Your planet looks pretty awesome. As to what comes to mountainous terrain not being visible from long distances, you're absolutely right - but it's still worth it having it on teh high-resolution textures, because then you can use the same planet texture for faraway shots (mipmapping/resizing takes care of mountains becoming indistinguishable except by terrain colour) as well as skybox material - from low to medium orbits the mountains would definitely be visible. Probably even from high orbit. But not really from, say, Moon distance from Earth.

The stuff about atmosphere colour and surface colour saturation is pretty fascinationg. :)

M87:  That is coming along very nicely. :)  I especially like the low-orbit view.  Would make an excellent rendition of the planet in the FS2 intro, in my opinion.
Good discussion on the atmo colors as well.  I'm curious about what colors could arise from various compositions.  Our solar system has quite some variety in colors, especially Earth's which includes nearly every color in the rainbow depending on how sunlight passes through it.  Or consider Titan with its orange fog below a blueish/violet haze.

The reason these planets would work so well is that they very closely resemble the originals, but aren't quite the same; especially the re-hued Mars copy needs a planet that has similar features to Mars, but isn't quite the same. The green-ish planet works almost as it is, since the lighting matches almost one to one the positioning of the retail planet. Watsisname's planet can likewise be tilted about -130 degrees to match the direction of the sun approximately.

If you want, watsisname, you could also re-colour the red planet's surface to closer match the brown/tan surface of the retail re-coloured Mars - that would kinda be icing on the cake. :)

If you're willing, could you post versions of these planets with the lighting direction fixed, as well as your "final touch" on them, so to speak? The format for the planets should be at least 1024^2 resolution, preferably 2048^2 (since current mediaVP versions of these planets are actually 2048^2) with blending to transparency (not black) on edges. I can deal with the conversion to DDS, if you just send me the TGA's or other uncompressed source files (TGA's just tend to be the best for that purpose).

Also, if you are willing to participate further, you could post versions of these planets in various phases, likewise to what I've posted. These could be included in the aforementioned background planet package so that different positions in solar systems could be used by mission designers. But that has no deadline whereas mediaVP content has... though no one quite knows when that is. :p

Here we go, final updates to the surface texture, clouds/dust, and a transparent background so it's good to go in Freespace.  The texture is 2000^2, so that should be good enough to use as a background planet taking up <~15 degrees of the field of view.

When I get a chance I'll update this with the fixed lighting direction and a few extra phases. :)

The previous one looked better to be honest. :nervous:

Also, by texture being 2000^2 (better practice would be to use 2048^2 though, better memory utilization) do you mean the surface texture wrapped around the sphere, or the actual planet bitmap? I'm hoping for the latter. But anyway, this latest one looks like you reduced the contrast (and brightness for clouds) or something like that, and the atmosphere effect obscures the surface significantly more than before.

Herra:  I refer to the texture before being mapped-to-sphere being 2k.  I'm not sure what "planet bitmap" means exactly, could you explain?  The width of the planet itself after being mapped is 1448 pixels (1500 with atmosphere) if that's what you were looking for. 

Also I think I'm letting my personal preference of having thick/obscuring atmospheres sneak in there again.  I can make a brighter/clearer one as well.

By planet bitmap I mean the end result, ie. a round image of the planet. The file that can be used by FS2 as a background image. :)

Anyhow, if the width of the texture is only 2000 pixels and you wrap it over a sphere, you only get 1000 pixels for a side, and the central area facing the viewpoint is stretched even more, so having the planet 1500 pixels wide will probably show some texture stretching and would probably looks better at half a size (750 pixels wide, the whole bitmap being 1024^2). But as I haven't seen the high-res versions, I can't really say anything certain about it.

Also like I said, it's good practice to use power of two textures. It hardly matters with GIMP (though it well might, who knows...) but it's a good habit to have. ;)

TopAce: The last one is not actually better or worse in itself, but it differs from the above image more than the former version, where there was more contrast between surface features... so for the purpose of replacing that in the game, the former one is, in my opinion, somewhat better.

Post by: watsisname on October 02, 2008, 11:09:13 pm
Thanks, I understand now.  I'll keep a habit of working with power-of-two textures and mapping to a smaller sphere in the future.

Tried making the contrast and coloration a little more like the original here.  Also, atmosphere on nightside actually darkens the background.  Woot.  :drevil:

Yeah. :v: took a shortcut with a lot of the planets...

planeta1 = something that looks like either water planet or very low res Neptune
planetb = Callisto
planetc = Europa
planetd = something clouded, either Venus or some gas giant. No detail to speak of.
planete = not immediately identifiable. Might be a heavy re-colouration of some solar system planet or moon, but might jsut as well be original work.
planetf = Mars, with some re-colouration to more yellow.
planetg = violet Jupiter.

And the same substitution was used in current mediaVP planets, so you see why I kinda want to get them renewed... ;7 Four out of seven were just ripped from solar system imagery and re-coloured slightly. Remaining three might be original or not, can't really tell.

Post by: watsisname on October 07, 2008, 07:57:31 am
FSF:  To be honest I think I like your planet better with a little atmosphere around it.  Also consider putting back the haze effect near the limb that you had earlier, but placed below the clouds instead of above them.  Aside from those minor things (which are up to personal preference, really), it looks pretty well complete in my opinion.  The land and clouds are good.  Maybe with a little shadow and bumpmapping to the clouds and it'd be perfect. :)

About the icecaps on the martian planet: those were painted on with the sand-dune and small-galaxy brushes, then bumpmapped, and distorted with the ripple tool.  Then the center of the caps were filled in with an extra brushing.

Aardwolf:  Nice nebulae.  All it needs now are a few stars put in the brighest regions.  Maybe a slight bit more blurring to the sharper areas as well.
Title: Re: Celestial Objects Thread
Post by: Herra Tohtori on October 07, 2008, 08:29:04 am
FSF: I don't really know what you mean by "keep doing the coastlines"...

I do notice that the continent facing the viewpoint in the latter version seems to be somewhat stretched equatorially. If it's what you want, that's fine; however, I've noticed that a more balanced continent shape comes from taking into account the fact that the texture is mapped into sphere; which means that on the equator, a square or sphere would need to be twice as tall as they are wide in order to appear as square or sphere... and then there's the matter of polar distortion. I've posted this image before, but it's a good example:

(http://users.tkk.fi/~lmiettun/Kuvat/Space/continents_sample.gif)

...looks like this in a "world map" ratio (2:1 instead of a square):

(http://i37.tinypic.com/2hnmmo6.gif)

...looks like this wrapped on sphere:

(http://i33.tinypic.com/2uggr3n.gif)

Polar caps are rather easy to make; just pick either white or very very light grey, aquire some kind of "coastline" to work as the edge of the ice cap (drawing it freehand can be quite tedious and difficult, since coastlines tend to have fractal-y structure), and colour the ice caps with the colour you selected. If you want, put some floating ice on some bay (galxy brushes in GIMP can be fairly useful for this) or stuff like that, but basically you just need to get the icecap's edge on texture and fill the polar region with uniform colour after that.

True, you can't see the coastlines in the above picture. Take a look at the picture below: notice the lighter blue/cyan around the coasts. I've seen it somewhere on an actual earth pic (which I can't find anymore), but it looks a bit funny in full-planet view.

watsisname, is this what you meant with the haze effect below the clouds? Should I put it under the cloud shadow layer as well?

I wanted to make my nebula prettier by adding stars to it. At first I was just going to add some HSV or RGB noise but that looked like ****, so I went back to the last version I had and manually put in some stars. I had a heck of a hard time figuring out how to create a custom brush in GIMP ... I spent 30 minutes fooling around with thed brushes dialog before I had the inspiration to do a ****ing google search. I finally got it right and made a brush for the halos. The big thing I'm displeased with is hpw the diffraction spikes are all the same length even though the halos vary with the with size of the star.

Suggestions?
Title: Re: Celestial Objects Thread
Post by: Retsof on October 07, 2008, 06:57:16 pm
What I do if I want a better starfeild effect is make the HSV noise but then go over it with the sparkle filter.

Post by: Herra Tohtori on October 08, 2008, 08:01:51 am
What I do if I want a better starfeild effect is make the HSV noise but then go over it with the sparkle filter.


My methods for making a starfield is as follows...

There are basically four types of stars you can see: blue, red, yellow and bright. The dimmest stars usually just appear "bright", meaning they have no distinguishable colour. Brightests stars like Sirius, Arcturus, Antares or Betelgeuze have clear colour onto them, although they too are primarily just bright... So I make some plasma, then make every other colour but blue, red and yellow transparent (gets rid of cyan, green, magenta, white and black) to form a random colouration map for the brightest stars.

Then I make some grayscale noise, apply brightness/contrast at about 60/110, duplicate the layer, apply brightness/contrast at about -60/40 to only get the brightest stars visible. Gaussian blur with value 2. Normalize, desaturate if necessary. Apply the colour map to this layer at about 50% intensity, and the normal starfield layer on top of that. Should look about like this:

(http://i37.tinypic.com/2nqekgj.png)


Aardwolf, make the differently sized stars on different layers. Same brightness/size goes to same layer. Then apply the diffraction filter on each layer separately, length varying based on the star brightness, and it should work quite nicely. Of course, if you did something else than a filter, then this might not work... :nervous:

You could also try and kinda blur the combined star layer before diffraction, and apply that to increase the brightness of the nebula. Right now the brightness of the nebula seems only adjusted by the diffraction filter around the stars, which is not necessarily good thing.


Another thing to keep in mind is that while that kind of diffraction might be accurate for a photograph taken with a telescope that has four support beams for the secondary mirror, human eyes see diffraction very much differently (and diffraction wouldn't be static anyways, so baking it onto the background imagery wouldn't necessarily be a bright idea)... For FreeSpace background use, keep that in mind; for art, you can do whatever pleases the eye most.

Post by: Herra Tohtori on October 08, 2008, 09:41:19 am
Basically? Yes. Although you should copy it to a power-of-two resolution (probably stretch it to 1024x2048), then save without alpha channel as a TGA (easiest way to do this is to select black as background colour and flatten the image, then save).

You could also use it as a skybox texture... like this:

To make the atmospheric "ring", use alpha-to-selection on the planet layer (after mapping it to sphere) to select it, then switch to the new layer, fill the selection with the desired atmosphere color, deselect and blur it a little bit.  Then reselect the same region as before and erase, and you've got just the ring.  You'll also need to erase the section over the darkside, unless the atmosphere has its own lighting effect in which case you can do something different for it.
The haze effect is made through the exact same method, except with inverting the selected area.  This way when you blur it, it spills onto the planet instead of into space.  This technique is not as realistic as actually rendering the atmosphere in a 3D program, but the effect is still pretty convincing I think.

Turnsky:  Nice image, very atmospheric.  Do you mind if I ask how you made those rings?  They're really good. :yes:

Well, from an artistic standpoint, the atmosphere can be any color you want it to be.
If you want to go with realism, then the color should reflect the type of planet it is, the composition of the atmosphere itself, and the color of the parent star to some degree.

(...) a square or sphere would need to be twice as tall as they are wide in order to appear as square or sphere... and then there's the matter of polar distortion. I've posted this image before, but it's a good example:

(http://users.tkk.fi/~lmiettun/Kuvat/Space/continents_sample.gif)

...looks like this in a "world map" ratio (2:1 instead of a square):

(http://i37.tinypic.com/2hnmmo6.gif)

...looks like this wrapped on sphere:

(http://i33.tinypic.com/2uggr3n.gif)
How do you get polar distortion working that good? I'm having severe troubles with it. What I'm doing right now, is dividing my texture horizontally in two parts and polarizing them separately, but somehow the parts don't fit together anymore when I've done that.

Post by: Herra Tohtori on November 22, 2008, 02:52:01 am
About the polar distortion; I cheat.

Basically, I make two different polar distorted textures of solid noise clouds - one for the upper and one for the lower hemisphere - and one undistorted texture in the middle. Then I usually alpha mask the layers so that the non-distorted texture will show up in the center, and the distorted textures are visible on top of that on the polar regions.

After that is done, I make adjustments to the contrast on the "gradient area" to equalize the contrast on the whole overall texture (alpha mask tends to reduce the contrast for some reason) and then Copy Visible, paste to new layer and adjust contrast/brightness to get the continents visible. Contrast defines the sharpness of the continents (usually takes rather high value to look good), while brightness defines the white/black ratio (I usually think the white stuff as continents and black stuff as oceans). The resulting continent map can be used as an alpha mask to a ground texture layer. For example. After the continent map is at this stage, you can manually erase things you don't like, for example little islands divided by the left/right edge of texture (they can be a ***** to colour so that no seaming occurs) and other stuff like that.

Sounds complex but it works reasonably well and is simpler than it sounds... Oh well, since images tell more than words, see attachment, it should make it rather clear what I'm doing.

The exact same technique can be applied to everything you put on your planets - oceans, cloud layers, terrain colouring layer... it works rather well most of the time. Sometimes you can notice two "lowered contrast" regions on the map left by the alpha mask, but usually you can deal with them, and when making continents it hardly matters since you're going to contrast the image to about two colours anyway. Oh, and this technique as I use it leaves the continent edges aliased. Working in higher resolution and using careful gaussian blur on the continents works on this issue, otherwise I haven't found anything overly wrong in it.

Leaving the contrast to somewhere like +120 instead of taking it directly to the max +127 also works, but it leaves the outlines of the continents and island quite fuzzy. Sometimes this can work, sometimes not so much.


Oh, and that planet looks pretty good. The rings look very recent, otherwise they would've evened out to form seemingly "uniform" rings, but if you justify the "cloudyness" by something like test fire of Death Star, then it works just fine. The starfield looks fine, perhaps a little dense to my tastes but fine in general.

canvas size is 3000x3000 but then I resize it to 2997x2997 so that it works in-game on dds format, for some strange reason, when GIMP compresses the file it doesn't show in game (that would cut the actual files from 35 M to a mere 8 M file).

I still can't get a good surface effect, I bumped the earth zones but as you can see I get elevation on the shores which does not look very realistic.

2997^2 is not any more valid resolution for DDS files than 3000^2. If you need a massive texture, use 2048^2 or, if you need absolutely gargantuan texture, work in 4096^2 canvas size to begin with.

Most of the time 1024^2 is of sufficient resolution for the end result though. Skybox planets are the only thing where bigger planets are justifiable.

So I should use 1024x1024 or 2048x2048 and the planet will show in game even if it is compressed?... I remember having this problem even with namplates on the past and all of the times the smaller file was not working but the bigger one was showing ok.

Yes, although based on the MediaVP beam issues, some older GPU's have problems with too small compressed DDS files.

Also, you need to decide the compression on case-by-case basis. Some planets compress well without visible quality loss, while some (mainly those with a prevalent atmospheric gradient) can develope nasty artefacts.

If you want to try compression for planets with atmospheric glow around them, you should probably use dxt5 compression. If there's no atmosphere (like Moon or other barren rocks), dxt3 might be better. If compression doesn't work, you can use uncompressed u8888 format, which is huge but has no quality loss at all. On the topic of mipmapping, it is usually better to make the planets have just one layer of correct size, but on the other hand mipmapped planets can be used bigger and smaller so they are easier for mission designers to apply without making them shimmer in the game.

What utility do you use to convert the images to DDS (and which compression format have you tried)? I'm relatively sure
Title: Re: Celestial Objects Thread
Post by: Rodo on January 19, 2009, 06:27:57 pm
I used a script for GIMP that I got from here (http://nifelheim.dyndns.org/~cocidius/dds/).

I've always used BC3 / DTX5 format, I've tried DTX5n format but I get a yelowish effect so I sticked with the former one for all FS files I've created so far.

about mipmaping, I've never tried the option since it was always complaining about the file not being x2 resolution (I guess we can try that now I know the common size) and I always make the file with a single layer, well at least when I save it.



Title: Re: Celestial Objects Thread
Post by: Herra Tohtori on January 19, 2009, 11:00:37 pm
You could also try the command line (and other DDS tools) that are distributed by NVidia (http://developer.nvidia.com/object/nv_texture_tools.html)... They give more options than the GIMP plugin, especially over compression quality which can sometimes be very useful, and mip mapping filters as well. And yeah they work even if you don't have NVidia GPU. Or, at least the DDS utilities does, don't know about the GPU-accelerated compression thingy.

Also, yeah. DDS textures are designed to have exponent-of-two layers because from memory point of view, that's the most efficient way of using the memory. Basically, a 400x400 resolution textures takes the same slot of memory as 512x512 resolution texture would. And 2997x2997 resolution texture requires, as far as I know, the same slot as a 4096^2 texture would, but wastes almost 75% of the slot it book for itself. Which is why it is always wise to use exact power of two resolutions; using something in between will waste memory. I am quite sure if you have ever looked at FS2 debugs, you have seen lines that say "N % wasted" regarding almost all ANI files. They work, but are not ideally sized from memory standpoint.

So yeah, you *can* convert a file to DDS format even if it's not a power-of-two resolution, but the full extent of DDS format's capabilities can't be used, and GPU's might have problems with it.

Reading the documentation for the file format helps to understand how to best use it btw... :p For example dxt5n is basically the normal maps format and it works by transferring red channel to alpha and multiplying green channel to red and blue, so yeah, saving to that format is a bad idea if you don't plan on using it as a normal map... :lol:

I tried making orion nameplates before but it gets too messy for me to follow instructions from tutorials, as it did when I tried to follow the tut you left on the first page of this thread, I basically do always the same way... try to keep up then I take what I like from the tut and apply it a way I can understand it.

Uhh ... you don't want a green background behind your planet.  That was only for PCX, which is OLD, and never supported an alpha channel.  DDS (DXT3 and DXT5) support full alpha channel.  DXT5 is probably the best.

did you actually erased the green parts that surrounded the planet?

green background was used only in pcx and the green part was rendered invisible by the engine itself (not quite sure about that), now with dds all that is not supposed to be there in game needs to be fully transparent.

I'm not following you in the white background... you get a white square in game or something like that?

As far as I know: Things that use alpha blending are put into BitmapX: list, while things that use additive blending (black=transparent, file has no alpha channel) will use Bitmap: list. The descriptions in the commentary of stars.tbl are a bit misleading due to volition's hack with the green=transparency on BitmapX PCX files... so planets and other solid objects go to BitmapX: while nebulas, suns and other assorted brightness-related, see-through backhround objects go to Bitmap:.

When you convert a non-alpha channel bitmap into DDS, you need to use either dxt1 or u888 format. When you convert a file with alpha channel, you need to use either dxt3, dxt5 or u8888.

dxt1a and dxt1c will be interpreted similarly by FS2_Open - their alpha channel will not really be interpreted as transparency. u888 (uncompressed, 3x8 bit channels) doesn't have alpha channel at all and it is useful for nebulas since it preserves gradient quality, while dxt compression doesn't deal with gradients well at all without some rather fancy hoops to jump through first. u888 is pretty much the only way to make things like Sun bitmaps look good...

dxt3 is good for textures with sharp transients between transparency and opacity, like Moon, asteroids and other objects. dxt5 is relatively good for gradient alpha transparent textures, but beware of artefacts again. Atmospheric gradient can easily become rather heavily artefacted while the rest of planet looks just fine, which is rather annoying.

A big advantage with uncompressed textures for nebulas and suns (anything wirh gradients basically) is that they upscale much higher without pixelation than dxt compressed versions.


Regardless of what filetype you select for the final texture, I recommend testing things as TGA beforehand. If you get the 32-bit RGBA TGA file to show correctly, the file converted from that should show up properly just as well. Basically what you need is to make sure that

1. Alpha channel shows 0% value on the transparent area
2. The alpha channel is saved along with the image.

Then it should just work when you put it on BitmapX and call it into mission. For comparision, open any planet in mediaVP's to see how the alpha channel should behave.

You could even try by making a white layer, then applying an alpha mask with white center and black edges on it...

OK, first, I want to thank you all for helping me out here. :) Secondly, I think I figured out why I keep getting a white background. When I read the information on the file, there is no Alpha layer. When I pulled one of the planets out of the 3.6.10 Vp's  it does in fact have one. So now I'm gonna ask how does one create a alpha layer in Paint Shop Pro 9? Apparently I thought you just click on the Transparent layer for color and now I see that's not so. If I can get that done, I'm pretty sure it will work.

Any Paint Shop Pro fellas out there know how?

Thanks again all :)

EDIT: SHAZAM! I got it figured out now. :) I found a tutorial on how to make Alpha channels.

Again thanks for all the help fellas :) You might see this planet...ummm soon. ;)

Post by: Jadehawk on January 26, 2009, 01:59:58 pm
First, thanks everyone for the kind words :)

Will I plan on releasing this? Yes I will as it's my first one as stated earlier. I also plan to make many more, but most of these you wont see until TotT gets released.

How I made the clouds? I will admit here now, they were the most time consuming part of making planets if you ask me. Honestly, it's a combination of using the Warp brush (I use Paint Shop Pro 9) on a Twirled image. The image for cloud making started using a random smudge to roughly a circle shape. Then used the twirl function until it was looking like a giant hurricane. Once I did that, I used blur just a tad bit. next up I used the Warp brush in several different sizes and this is where things need to be done carefully. I worked in small areas as much as I could as for some strange reason, the warp brush will delete large areas if your not careful. Undo is your best friend here! :)

Just keep working at it until you get a feel for the effect your looking for. And in my case, this is a ice-menthane planet that has high winds in most cases. Hence why some clouds look very smooth and not so puffy. lastly, use the Soft or blur just a tad to give the clouds some softness and don't over do it! just when you think you can do more, stop and your done.  Note, I redid this three times before I got a hang of what I was doing and I'm sure you will too! ;) Another thing, I went back and forth with the warp brush and twirl function until I got what you see. You may or may not need too. All depends on what you want for your planet.

Yes I can see the unusual areas in the dark areas with the clouds. I have looked into this and what you see is just the clouds in the dark areas interacting with the night filter for the planet. Looks unusual yes, but I think in real life, it might be somewhat the same.

Yes those are lights you see in the dark part of the planet and once you get a close look, you will see they are in canyons and deep areas of the planet and only lights from building are there. Nearly the entire planet lives under ground in large central places like that movie with Arnold Swartzanagger and Sharon Stone on Mars.

It started out as a Mining planet, but since Cappalla's star went POOF, this far end of the GTVA became more important and Dubhe IV got the 21st Battle Group and a new headquarters.

But that's my story and yours can be different too ;)

I'll release this sometime soon. :)

It's really a wonderful piece of work there! :) As for the glow on the dark side, I'm not so sure it's supposed to have a glow around that part? But having said that, I'm willing to be corrected if such is in fact real.  On my work, I also struggle with how much to add or should I add any at all.

Looks good, just a couple nitpicks on the rings.  You must have used a color-to-alpha on them because they do bot block out the starfeild on the shadowed side.  Also, wouldn't the rings still be visible when shadowed because of the light from the planet itself?
Title: Re: Celestial Objects Thread

Post by: FreeSpaceFreak on February 11, 2009, 05:14:04 am
Well, thanks for the constructive criticism everyone :)

Retsof, in reality the rings wouldn't block out all starlight either; they're just a lot of rocks orbiting a planet, but with enough space between them to let some light pass through. I might try and make the rings be lit by the lava a bit though, I like the idea.

Post by: watsisname on March 05, 2009, 12:37:12 pm
The atmosphere and terrain are really well done and faithful to the original, but I can't help but feel it's missing something.  I think it's really hard to tell what exactly is going on with this planet just from the scene...  somehow it always struck me as a frozen planet with an atmosphere, but that could be subjective.

At any rate my suggestion would be to add a little extra variation to it, this could either be from some clouds (not too much since I don't think you want to hide too much of that nice surface), or just some small brightness/contrast differences directly to the surface to give it a bit more flavor.

Title: Re: Celestial Objects Thread
Post by: watsisname on March 06, 2009, 05:58:11 pm
When you say Sol bitmap, what sort of look did you have in mind?  Visually it's just a very plain, slightly yellowish disk with maybe a few sunspots (which would barely be visible from a distance, if at all considering all the glare).  SunGold would probably be the closest approximation we have ATM for the visible Sol.  Or you could have a detailed and active look with flares/prominences/etc such as from a hydrogen-alpha image like this:
(http://weblogs.newsday.com/sports/watchdog/blog/sun_main.jpg)
Title: Re: Celestial Objects Thread
Post by: Herra Tohtori on March 06, 2009, 06:40:47 pm
This was discussed in length on Stellar Enhancements thread and after several tests it was concluded that for a pilot, the primary nature of stars would be their immerse brightness; details would not be visible and even colour would be a secondary feature due to human eye's (and brains') ability to adapt to white balance for different lighting conditions very fast. Colour of the star has more of an impact on the lighting than the visual appearance of the star.

Not to mention the fact that at Earth distance, Sol is about half a degree wide (same size as full moon from Earth's surface), approximately anyway. Don't try this at home, but you really couldn't see any details on the sun even if you were dumb enough to look at it directly with plain unprotected eyes. If you used welding glasses or other tinted material to reduce the brightness, you could probably see the biggest sun spots but not really that well, and flares and protuberances would be right out of view... plus you would kinda have harder time seeing them enemy fighters clearly. :p

This thread is teh awsome... :D

Texturing the Zephyrus was getting repetitive and kinda boring, so I thought I'd play around with planets for a while.

I tried Terragen 2 for a bit (3-4 days), but I got lost -it was hard to make it do exactly what I wanted it to do. It had a tendency of splattering mountains all over the place, even when I blended its shaders. So I went back to my trusty MAX 7 and, as an act of defiance,  slapped this baby together in...oh, an afternoon more or less.

I'm thinking of toning down the brightness on the top right part. It's a bit 'blinding'

The uploaded image is 800x800. If anybody wants it, I can provide renders up to 2048^2.

I'm thumbnail linking to it because the rings only look good when it's 2048^2. I flapped a glow effect on them (hey, they're ICE! it GLOWS! :p) and it kinda sucks at lower resolutions. I can downsize it, but it'll need another render.

Question for the planet artists here: has anyone seen this before, and more importantly, do you know how to fix it? (Effect slightly exaggerated.) Gaussian blur does nothing. I think it's caused by playing with the colour/brightness , but I can't work it away. Even when I down-scale the planet to 2048x2048, it's still visible. :mad:

Well there's two things that can cause it...

-Color banding of your display (this happens quite often with LCD's, for more information look here (http://www.lagom.nl/lcd-test/gradient.php). This causes even the smoothest of gradients to show some amount of banding (or rather they seem to use slightly different RGB balance to achieve different brightness values, and thus the image doesn't appear as uniform gray). If you see banding on the images on that site, bad luck; get a CRT or better display. Mine shows some banding on the darker tones as well, so you need to just learn to see what is caused by the display and ignore it, and what is caused by image editing.

Wide gradients (large areas) of low contrast and brightness usually suffer from this the most of all.

-Image editing. Because the images we use currently have usually only 8 bits per channel and 24/32 bits per pixel, it means that when you edit something like smooth gradient with contrast/brightness/hue changes, rounding errors start to appear - you can check this out by taking a photograph that shows something like sky with a gradient, then start editing it (colour levels, back and forth, contrast/brightness with small changes)... With multiple edits, rounding errors start to accumulate and bands like that can start appearing in the sky. Same with calculating the final colour of a pixel with multiple layers with transparency.

If you can use 64-bit image mode while editing, you can decrease this problem as far as rounding errors go, but unfortunately your display will still only be able to use 32-bit colour mode, and in the end you need to convert the image to 32-bit (or if you don't need alpha, 24-bit) colour mode.

-...and yeah, image compression can do bad things to gradients as well. DXT compression uses less than 8 bits per pixel for some channels. It is not good for anything with significant amount of gradients in it. Use u888 instead (or u8888 if you need alpha).

@Herra, I think it's something to do with the Shader Tree, I have a similar problem on Vue if I try to put a volumetric object inside a refractive one, such as putting a cloud inside a glass-sphere, the renderer simply cannot handle the kind of maths involved. It's fine as long as the volumetric object doesn't touch the sphere, but as soon as they intersect, graphics hell breaks loose.

It seems it has more to do with alpha channel or something. In the render, the thing looks fine, but when I slap it on a black background, the part of planet behind the ring is lit up - or maybe it lights up the ring.

Oh well, I can cheat by rendering the ring and the planet separately and joining the images together later. Just takes two renders instead of one... :blah:

Title: Re: Celestial Objects Thread
Post by: watsisname on November 06, 2009, 03:51:47 pm
Double Post!

For a while I’ve been poking around with the idea of taking planets from the solar system and altering them to look terraformed, ie, earthlike.  The most logical ones to use for this purpose are Venus and Mars, since they are both terrestrial worlds near the habitable zone.  Personally I’ve just been working with Mars but I may try to do one for Venus in the future.

Here’s how it works.  To start with, you’ll obviously need a surface texture for your planet.  Using this with any of the aforementioned GIMP-planet tutorials should give you a nice looking rendition.  Here’s what I got for Mars by using a 4096x2048 texture:

(http://img237.imageshack.us/img237/6459/redmars1024.th.png) (http://img237.imageshack.us/i/redmars1024.png/)


Now for terraforming.  In the case of Mars, this means making a thicker, bluish atmosphere, adding clouds, a biosphere, and possibly most important of all, OCEANS! \o/

For realistic oceans, you need to decide how deep they will be (how much of the land will be covered?) and then figure out what parts of the surface are below that threshold.  For that, you need a heightmap.  Do a google image search for ‘mars elevation map’ -- the first result is a good one and I’ll refer to that in this example.
In GIMP, place this over your surface texture.  You may need to resize it and use offset to get them to match each other correctly.  Now you need to make a selection on the heightmap that contains a given range of altitudes.  To do this, use colors > map > ‘rotate colors’.  What you’re doing is taking a select range of colors (altitudes) and changing them to a single new color.  In this case the only unused color you can change them to is somewhere between violet and magenta, so on the ‘to’ colorwheel, make a tiny sliver in that area.  I suggest going from 1.6 to 1.61 rad/pi.  Now go to the ‘from’ colorwheel.  The lower limit of the selection should be below the bluest color on the map, I’d use 1.5 rad/pi.  Now swing the upper limit around clockwise from there and watch the preview, you’ll see a progressively greater area change into a purple color.  This area is what will become the ocean.  I used something around 0.6.

When you have a good color range, go ahead and hit ‘ok’.  Now you’ll select the big purple region with the ‘select by color’ tool.  You will likely need to play with the settings for feather edges and threshold, and press shift while clicking in several areas to get the whole region selected properly.  Once you’ve got all the purple selected, bucket fill the whole selection with a blue ocean color.  You might need to bucket fill a few times to get the edges right.
Make sure this layer has an alpha channel (right click in layer tab, ‘add alpha channel’), and then invert the selection and clear.  Now it’s just your oceans sitting on top of your surface texture. :)

Now add the biosphere.  For this, get some good looking image textures and lay them over your surface.  A lot of experimentation is key, some textures will work well, some will not, and be sure to use different blending modes and play with the colors/contrast etc.  You may also want to use different looking textures with certain regions of the planet or at certain altitudes.  For Mars, it’d be more realistic to only have plantlife up to a certain altitude, as the air will be very thin higher up.

Once satisfied with your surface go ahead and map to sphere, add the atmospheric effects, clouds, and anything else you like.

My result for terraformed Mars:

 :eek2: Really liking that. But, a suggestion: We know that Mars is, in terms of temperature, way colder than Earth. That would suggest to me that you would get substantial icecaps, which your terraformed Mars is missing.

Artificially-induced global warming?  You shovel enough greenhouse gases into Mars's atmosphere, and I'd imagine that you could at least partially overcome its distance from the Sun.
Title: Re: Celestial Objects Thread
Post by: The E on November 06, 2009, 05:37:37 pm
True, I suppose. But as it is, that planet has no ice caps at all, which looks a bit unnatural (Well, more unnatural than a green and blue Mars...). Of course, you could keep it like that and put a few giant solar collectors in orbit to give Mars that extra bit of energy...
Title: Re: Celestial Objects Thread
Post by: Droid803 on November 06, 2009, 08:19:40 pm
Well, it is unnatural.
Terraforming is a completely artificial process. You could get the end result to try and maintain itself, but sometimes active input (such as bigass mirrors) make more sense.
Title: Re: Celestial Objects Thread
Post by: watsisname on November 06, 2009, 11:06:31 pm
The E:  You are right and that's a very good point; you would expect to see polarcaps on Mars even after terraforming (water ice instead of CO2 ice though), unless the global temperature were raised to an extreme degree with a massive greenhouse atmosphere.  But that'd be kind of useless because then people couldn't live on it without respirators...
Anyway the surface texture I used actually has the real polar caps present (large one at north pole, tiny one in south) but from the camera angle I used when spheremapping, neither cap is visible.  My preference here was to center on the equatorial region to show Valles Marineris, the Tharsis volcanoes, and Hellas Basin in a single view.

As for Mercury texture, if I recall correctly there is not yet a complete mapping of Mercury's surface (I recall a lot of the images I've seen of it have a big swath of empty space near the northern pole).  Might have better data after Messenger enters orbit. =P  But then of course I could just render from whatever side has nothing missing. <_<  I'll take a look and see. :)

The three fly-bys that Messenger has made as part of its complex multi-year orbital insertion have pushed the total mapped area to something like 98 percent (http://www.nasa.gov/mission_pages/messenger/media/flyby_20091103_press.html), actually.  I don't know how usable the images will be, since they might be a bit patchwork, but I'd imagine there's at least some shot out there that you could use for an in-game graphic.

you got some talent there, something to note about the planets:

2335 one has a weird transition between swadow and light parts, it's like the green colour is lost far too fast.

2456 one you can note the emboss layer you used to represent the clouds, specially because you left a lonely one far on the light side, it's too notorious and might help blurring the black colour, and maybe some ice on the poles could work as well.

aside from that your work is great, you keep going man!

VENUS? Although the terraforming is very cool looking, that is... very much impractical. Being that close to Sol, the planet could not concievably ever be like that; if it were ever at that point [terraforming-wise] at its current position in relation to the sun, I presume that your Earth-like atmosphere would be rapidly scorched, etc., etc.

Venus is as it is now for a reason...
Title: Re: Celestial Objects Thread
Post by: Droid803 on November 17, 2009, 01:40:41 pm
Well, you could put giant shades in.
Apparently it would be habitable after terraforming, according to wikipedia and some other sources. Because terraforming would involve lowering the temperature as well, through whatever means.

I also recall reading that making earth-air filled floating colonies in the Venusian atmosphere would work too. (Apparently temperatures where the venusian atmosphere's pressure is ~1 atm is about Earth temperature (0 - 50 degrees celsius, which is a fairly comfortable range, actually). Though that is not terraforming, merely colonization.

 :mad:

... I was writing a response to your statement when the session timed out... hence "mad."

The temperature is an inherent problem which couldn't be dealt with easily at all. Now, I'm not about to say it's impossible - that's not "how I roll." However, impractical? improbable? Oh yes, that says it all...

The expenditure of resources, both in the build-up of the terraforming as well as maintaining that environment would be... ludicrous, to say the least. Without intervention by man... that planet would revert to its nasty Venus self, I'm quite certain. The only other planet in this solar system which I think would be able to maintain a "terraformation" would be Mars, and even that would be dicey if my understanding is correct. Without an active/spinning core, Mars is sort of "dead;" the field that a planet's core produces protects it from the dangers of space as well helping in retaining an atmosphere. Mars definately has an atmosphere, but it's not much...

...I wonder if part of the solution for Mars wouldn't be literally "building" an artificial moon about the planet to get the core to start moving...
Title: Re: Celestial Objects Thread
Post by: watsisname on November 17, 2009, 03:23:31 pm
Thanks for the feedback guys. :)

Re: Thaeris:

The terraformation of Venus would be take significantly more effort than it would for Mars, but I do not believe it is economically impractical (well today it is, obviously, but several hundred years from now, who knows).  I believe that the value of a habitable Venus would justify the cost of terraforming it, though it would be much more logical to start with Mars instead.

On Venus, there are the following problems to be dealt with:
1:  Too much heat.
2:  Too thick atmosphere / too much pressure
3:  Non-breathable / poisonous atmosphere
4:  Length of solar day, which is 116 earth days
5:  Lack of magnetic field.

Problems 1, 2, and 3 are closely related.  If you remove enough atmosphere to bring surface pressure to earth level, as well as replace the CO2 with nitrogen/oxygen, then a great deal of that heat would be released.  However, the sun's apparent size is 50% greater from Venus, so it is likely necessary to deflect much of that light through orbiting mirrors or soletta.  Once solar insolation is down to earthlike levels there should be no reason for Venus to revert back to a hot/toxic environment.
As for the length of day, that’s quite a big problem, too.  Not just for biology since here it has evolved to a 24-hour cycle, but having such slow rotation would likely cause strong winds to balance temperature differences from the day side to the night side.  I’m not a climate expert though so I don’t know how severe they would be.
Magnetic field would help preserve the atmosphere but might not be as necessary as the other fixes.

if the transformation does result in high winds then you will probably be looking at living in bioms or subterranean until they can be controlled (look at the extreme storm systems we get on Earth as i suspect these would at the least be the norm) this would provide the means for controlling day night for crops etc through shutters and artificial lighting

point 5
i suspect a possible answer would lie in Magnetic sails (http://en.wikipedia.org/wiki/Magnetic_sail) and an  array of satellites utilizing an adapted form of the technology

That's indeed interesting, watsisname. I assume by economic value you're referring to Venus' mineral resources... though I could be wrong.

The slow rotation would have a considerable advantage for solar power (reduced living costs?), though for the most part I feel it would be down-hill from there. Without specialized crops, the plant life might suffer rather harshly (countering the reduced power bill by having high grocery bills...  :P), and I assume the climate would be exceedingly dry (and you thought Arrakis was rough...  :nervous:). Thus, I predict epic, horrendous forest/prairie fires on terraformed Venus.

Not just for its mineral resources, one wouldn't even need to terraform it completely to get those.  But imagine the value of having a second planet the size of earth for people to live on.  ;7

Why would the climate be dry, though?  Surely water could be brought in from elsewhere?

Aye, Caerulean (or Cerulean) is a name for the bluish range of colors.

Edit:  As for the banding, I think it was from altering the gradient around the star -- I'll need to be a lot more careful when I do that in the future.
I reworked it from an earlier version, turned out to be easier to fix than I thought it'd be.  There is still a little bit of banding but it is near impossible to remove completely, should be a lot better than it was though.  Thank you for pointing it out. :)

Clouds are very high, terrain very... bland somehow, de-saturated? Hard to tell landmasses from water. The city lights are somehow strange too. Low resolution, too bright?

Also, the Moon is lit incorrectly, giving an appearance of a very small satellite closer to the view point than Earth.

As far as starfield goes, there's a starfield skybox that uses the real stars as seen from Sol system or nearby space (shameless plug) so you might as well use that. It includes automagical milky way effect caused by dim stars. :p

Would it be possible for the individuals who've made planets in this thread to maybe upload some proper TGAs or DDS files with the correct Transparencies to somewhere like FSMods?

Clouds are very high
Noticed that too, thanks, I'll modify that right away.

terrain very... bland somehow, de-saturated? Hard to tell landmasses from water.

Mmm.. maybe if I set the texture as normal, I'll check that, the hole hard to tell landmass from water is because of the atmosphere color, maybe If I tone it down a little bit it will work better.

The city lights are somehow strange too. Low resolution, too bright?
The map is definitely too bright, also I think I'm using the wrong method to render it, will try to improve it.

Also, the Moon is lit incorrectly, giving an appearance of a very small satellite closer to the view point than Earth.
I don't understand what you mean, the moon should be bigger or better lit?
I've said nothing.

Problem is that most of the times, work is done specifically for a particular mod...like special content of some kind.
Could probably make some new stuff and tag it completely mod free, but that's only happening when I'm satisfied with this one.

Post by: Herra Tohtori on February 14, 2010, 04:12:43 pm
Think of the direction where the light is coming to in case of Earth and in case of the Moon and I think you will notice what I mean.

The Moon is more a crescent form which suggests it is more "between" the view point and the sun, while the Earth is lit more than halfway, which suggests the sun is somewhat "behind" the viewpoint.

This puts the Moon between the Earth and the viewpoint, which makes it appear unrealistically small relative to Earth in this image.

Can't really explain it any better than that.

Title: Re: Celestial Objects Thread
Post by: Rodo on February 15, 2010, 02:14:15 pm
nice, how did you make the atmosphere glow?

I made it this way, you can probably find a better or cheaper way since I'm no expert on this subject, anyways..

First of all make a new sphere a little bigger than the surface and put it on another layer, then:

1- Turn Fresnell to around 3, in the Mirror trans tab.
2- Turn Trashadow on, in the shaders tab, then play around with the colors your material will have, not sure if they are needed or not.
3- Turn on Traceable and Shadbuf if the are not already, in the Links and Pipeline tab.
4- Add a color ramp with the colors you want your atmosphere to have.
5- You'll have to use nodes to make the atmosphere look good, add the filters: Color-> RGB curve, Filter-> Blur and Color-> AlphaOver, connect the RGB curve to the atmosphere image, it will allow you to modify the color of the final render without having to render again, same with the blur, only that it will control the blurriness (?) of the sphere, and the alpha over is to combine the image with the terrain one, it takes the color black as alpha channel color if I'm not mistaken.
Take a look at the values, play around with them and you'll get what you need.

Oh remember to turn on composite on the Render layer, so you can use different render layers at the same time.

Here's an image of most of my settings in blender:

Might as well show off this here. It was one of the iterations for BP:AoA Earth skybox but it ended up somewhat different in the end...

(http://img21.imageshack.us/img21/6372/earthindonesiaatmostarf.png)

Anyway, this planet was made with the help of this tutorial (http://blenderartists.org/forum/showthread.php?t=132869), I basically re-built the model and adjusted some values to my liking. It's like having a multipurpose planet model now.

Textures were from Blue Marble, and I used 21600x10800 resolution textures for this mainly because the higher ones caused Blender to just die in shock. On Linux, that is. On Windows XP using textures bigger than 8192^2 seems to trigger termination of the program.

True, on XP you can't use textures that big, I had to stick with 8192x4096 tops, and even with those I still get crashes when rendering, it's a bit frustrating to have a 20 minutes render to only get a crashed blender at the end :mad:


BTW your planet looks awesome, better than mine in most areas, I'm particulary interested on the spec options, how you did it? you used a spec map with land-ocean being b&w?

It's on track, I'll be releasing a skybox to the public in a couple of days... I just have to get a clue on how to fix that seam problems on the skybox using blender.

Title: Re: Celestial Objects Thread
Post by: Herra Tohtori on February 20, 2010, 12:26:18 pm
When you have everything in Blender, render the sides of the cubes in 2040x2040 or 4080x4080 resolution, so you don't need to rescale them.*

When you have them rendered, open them up in PS/GIMP, enlarge the canvas to 2048^2 or 4096^2 so that there's a thin border around the actual image. Then, you fill the borders with the edge of the adjacent sides of the cube, so that you basically surround each texture with the four sides next to it.

You need to do it for each texture, so it can be a bit time consuming and tedious, but it works and end results are spectacular.

After you're done, flatten the images and save it, and then you can convert it to DDS for final game usage.


And yeah, I used a specular map of Earth, which was also from NASA/Blue Marble. Look into that tutorial, it is a gold mine. As soon as the hardware and software can handle it, I'll be using the full resolution Blue Marble data set, though. That's four times higher resolution than what that planet uses... giving you surface resolution of 500 metres per pixel.


Regarding skybox resolution: 2048^2 (0r 2040^2 with the seamless method) is sufficient for most cases, but you will likely want to save them in uncompressed format (u555 for starfield only, u888 for content that has more colour depth) which means they still use a lot of memory. It will also suffer from upscale-blurring when you want to reduce the field of view.

4096^2 (or 4080^2) on the other hand is huge and that means you can use smaller field of view (-fov setting in command line) and still retain crisp, detailed look of the background, and as an additional advantage you can get away with using dxt1 compression, which has a compression ratio of 1/6.

That means that if you just used single layer, non-mipmapped backgrounds, then 4096^2 dxt compressed file is actually more memory efficient than a non-compressed, 2048^2 u888 file. However, you'll likely want to include two levels of detail mipmapping in larger resolution skybox, because otherwise the shimmering at higher field of view gets just a tad bit excessive...

Command line for this is as follows (assuming use of nvdxt):
nvdxt -file <4096^2-textures> -dxt1a -quality_highest -nmips 2 -sinc

Chances are he has at least OVER NINE THOUSAND megabytes of RAM.

Actually I only have over four thousand megabytes. Four thousand ninety-six to be accurate. The render was done on 64bit Linux, so all 4 GB were in use. My CPU is an AMD64 Athlon X2 6000+ and the motherboard is Asus M2N-Sli Deluxe with FSB of 400 MHz (DDR2 memory runs at dual rate of 800 MHz) which has nForce 570 chipset.

Nothing too extravagant, as you notice. It just takes a lot of patience to work with this sort of textures. Render times are often quite long. ;7 I really should look into how to hook my other computer (AMD64 X2 4800+, 3 GB [email protected] [200 MHz FSB] ) into a render farm of two PC's...

Aardwolf: I suppose some sort of reddish hue effect could be added near the terminator. I'll research on that bit when I'm working with the model next time. ;)
Title: Re: Celestial Objects Thread
Post by: Rodo on February 20, 2010, 08:46:08 pm
I'm surprised, and you can actually work with that kind of texture sizes? I got several crashes after trying to open a 21600x21600 texture in blender and even in gimp... I figure it must take ages to open a file that size for you as well.


Back on topic, I'm having troubles with my render, It turns out that the clouds are not blocking the citylights after all :ick:.

I'm using a crazy method to render this (sorry if your eyes hurt after reading the following):

I made a new sphere with a lamp opposite to the sun and then set to no diffuse. Then I just place my citylights texture on the sphere and set it to affect the spec and the spec color, after that I play around with the specularity filters untill I get the amount of lights I want.

Problem is... I can't seem to find a way to block the specularity from reaching the clouded parts of the citylights map, you guys have an idea on how to do this?

I might have to go all the other way and use the other method described on the tuts, the one with the emit texture with a second mesh covering the day side.

I think it's too consistent across too large an area - the coastlines all seem to have an identical gradient, the terrain is all green etc. etc. add some deserts and randomize that pale blue drop-shadow (I think :)) you used on the coasline a bit.
Title: Re: Celestial Objects Thread
Post by: Herra Tohtori on March 29, 2010, 06:26:27 am
What I really like are the distribution of landmass, the clouds and water. Polar areas seem a bit hazy though, and land texture could be a bit more crisp.

And like BW said, the highlights on the sea next to the ocean are somewhat bright - I usually don't brighten the water around countinents, but instead try to turn it into somewhat greenish hue from the deep blue on shallow regions. If you have the planet source material around in layered mode, I recommend playing with colouring the highlight to yellow and then testing different layer modes to produce a shallow-water sea-green effect that you like.

Overall, I really like it. :)

That's your first attempt? very well done.

You'll learn new tricks in the way.. for now I would say you could add a gradient layer over the planet mass to simulate the atmosphere.

What program are you using to make the planets?

Thanks for all the advice!

Changes made:
New texture overlayed on the original for sharper terrain.
Lightened the whole thing a bit.
Toned down the coast, and made it a little more green than blue.
Increased the atmosphere effects.
Added new terrain types. They're subtle, but there is now grassland, plains, and mountains. Sorry BW, I couldn't bring myself to drop deserts on a jungle world.
Added a little more cloud cover, while cleaning it up all around and adding a bit of shadow to the clouds.
Rivers!

then make the copy layer like....30% alpha transparent.

I agree there.  Also I feel the brightness is a little bit too uniform over the dayside -- if you can have the intensity drop off a little bit as you go from the full-lit areas to the terminator, I think that would help get a more photo-realistic effect.  I also notice what seems to be a very narrow atmospheric highlight/haze across the sunlit limb, which if expanded out a bit might help in that regard, too.

As for everything else, I really like your landmass shapes, distribution, and texture.  The polar regions especially look great.  The surface colors are a bit vivid in my opinion, but the variety and detail are good.  All in all this is fantastic for a first planet.  Keep it up! :)

----------------------------------------------

On an unrelated note, I played around a bit with making more "realistic" atmospheres in GIMP, especially with trying to mimic the way that colors change from the day to night side, and the "haze" effect near the limb.  Here's what I got when trying to reproduce the earth's atmosphere.  There's some nasty banding going on that I need to fix, but at least it shouldn't be too noticible when actually placed ontop of a planet.

Why is the haze circular-looking? Shouldn't it be an ellipsoid extending from pole to pole like the terminator is?
Title: Re: Celestial Objects Thread

Oh, Earth was just having really spectacular weather at that moment.  ;)
Nah, I left it cloudless to demonstrate how it looks when placed over the planet texture.  I thought clouds would get in the way a bit. :)

Why is the haze circular-looking? Shouldn't it be an ellipsoid extending from pole to pole like the terminator is?
My understanding is that the intensity of the haze is dependent on the amount of air that a ray passes through going from ground to the observer (same reason why distant mountains look bluish), so it's strongest at the limb and decreases toward the center of the disk, which would imply a circular effect if the planet is in full phase.  (See image in orbiter below).  But obviously if the planet is not full phase, then the haze intensity would also depend on how strongly lit each portion of the surface is, being strongest at the sub-solar point and weaker near the terminator.
The intensity of the haze, and how rapidly it drops off going away from the limb, are up to artist choice I think.  So far I haven't been able to find a good photo of earth that shows this well, but my preference is for it to be a bit strong but also spread out.
Lastly colors should become redder closer to the terminator, and even more so when viewed from the darkside (crescent phase planets), to account for Rayleigh scattering.

You might want to use Minnaert shader instead of Lambert.

Also, Jupiter should have no atmospheric glow around it as seen from distance like that. Just clear transition from space to planet.

well, star out big with large coloured stokes, then use the Iwarp (liquefy equivalent of photoshop) to make your swirls and storms,
takes some training but I manage to do it fairly reasonable.


Also, Jupiter should have no atmospheric glow around it as seen from distance like that. Just clear transition from space to planet.

not sure about that, I mean if considering its gas giant nature, the whole thing is one atmosphere, so a little fall off wouldn't hurt, if rendering it for one hides hard edges. The glow is just not as dominant as on earth like planets which I think is because of the scale.
(radii are approx. 1: 22 )

With Jupiter, there is a haze layer at 0km altitude (0.1 atm pressure), with cloud layers appearing about 30km below this point.  Pressure drops off to 10-3 millibars at 320km altitude so let's consider this to be the boundary of the visible atmosphere, thus the visible depth of the atmosphere is approximately 350 kilometers (obviously this is a very wish-washy figure since it's hard to say how high up the upper boundary of the visible atmosphere is, but probably 300 to 400km is a reasonable estimate).

Jupiter's equitorial radius is 71492km, so using the 350km estimate of visible thickness, then the ratio of atmosphere to planet radius is 350:71492, or 1:204.  You could consider this to mean that a Jupiter planet bitmap of 2048 pixels radius should have an atmospheric halo effect of only 10 pixels thickness.

Doing the same calculation with Earth, we can estimate the ratio to be about 100:6371, or 1:64, which is about three times more prominent than Jupiter's. :)

Good work. :nod:

This is what I mean - the relative height of the visible atmospheric haze is so small that, in most images and renders, it should be covered by anti-aliasing of the edge of the sphere. In fact, same holds true for Earth as well for most shots taken from high orbit or further; the atmospheric haze really is only visible from LEO.

And that's a 2048 pixel radius. That means the bitmap itself should be at least a whopping 4096^2 in size. Not really useful for a background bitmap...

Now, with the available textures for Jupiter, making a render of this size makes little sense because the source textures' resolution starts to be at or beyond their limits - ie. the surface starts to pixelate.

The problem is even more pronounced if you're making a skybox (which, IMHO, should be the preferential method of putting planets on the background). If you wanted any sort of haze to be visible, you would have to put the camera so close to the planet that the textures would be atrociously pixelated. You would have to blur the basic diffuse texture, then somehow add your own high-resolution imaginary cloud system details - doable, but rather tricky for obvious reasons.
Title: Re: Celestial Objects Thread
Post by: eldain on April 15, 2010, 03:20:20 pm
Just because of that I start with a 8192^2 picture, which I transform and then downscale to 4096^2, just because you lose information
when transforming (in photoshop that is, its less apparent in renders as it crops outward, leaving the closest part as the standard "normal" resolution)

secondly, that it might not be visible clearly on the outside is one thing but fall "off", falls inwards as well. I always feel, (and that is my personal opinion) that the inward glow and outward edge blend better if you use a fall off, even when only very small and on the brink of being visible at all.

Post by: watsisname on April 15, 2010, 07:16:32 pm
I agree, eldain.  I think in most cases a bit of a fuzzy atmosphere halo looks better than a pure crisp edge, especially if you're dealing with aliasing.  I like seeing how things should look in reality but sometimes some stretching of the truth is not a bad thing either. :)

Nice first planet!  The surface texture looks good, and the nebula/starfield is a nice touch.  One suggestion I'd make is to move the shadow layer a little -- it's not quite covering enough of the planet so it looks more like an eclipse shadow.  'Tis a minor nitpick though -- great work overall. :)


On an unrelated subject, I was curious about figuring out the details of how different parts of earth look like [color-wise] from a great distance.  I'm thinking maybe the color information might be useful when making surface textures and atmospheric effects in future renders.  For my reference image, I used a photo taken from Apollo 16 of the earth in gibbous-phase, and did a little bit of adjustment in GIMP to get the colors closer to what I think they would look like to the human eye.  Here's how it looks after adjustment:
(http://img697.imageshack.us/img697/9943/photogibbousearth2.jpg)
*original image here:  http://img293.imageshack.us/img293/5792/as1611818885.jpg (http://img293.imageshack.us/img293/5792/as1611818885.jpg)

I checked this out further in GIMP with the color-picker tool and made a list of the actual colors over various parts of the image, specifically for what the desert/forest/ocean regions are in the center of the planet disk, and how the ocean color changes as you get closer to the limb, and lastly, the sunset colors.  For some things I averaged the colors over several regions to get a better determination... the true accuracy of this obviously depends on the camera and its settings used to take the photo, plus it's all skewed by my altering of it, but the result is still pretty photo-realistic in my opinion.  One thing I found rather interesting is how similar the forest color is to the ocean color... it's not so much "greener" as it is "lighter", as you can see below...

Regions selected:

Something's wrong with the edge of the shadow.

the shadow works nicely going from dark to light but there is as sudden change from about 25-50% gradient to clear with an odd artifact along the transition emphasising the fact.

also I'm not to keen on the hazy blobs which i presume to be clouds, the lack of definition contrasts horribly with the nicely detailed layer below it, and i think the blobs can be happily dropped as the layer below is awesome some and has a slightly menacing alien feel

Not to nit-pick (but I guess I will), but shouldn't both celestial bodies in that image have the same amount of illumination, in that the larger has a half-phase and the smaller has a quarter phase.  I believe that they should both have the same phase.

Very nice work, Aard.  The surface color and texture looks great, as does the lighting.  One suggestion I'd make might be to play with the atmospheric effect.  It seems like the intensity drops off too gradually as you go farther from the surface, (also it's veeery faint overall) but maybe it's just me.

It looks pretty good, so this program makes the planet all by itself or it uses textures as reference?

For the next step maybe adding normal maps or some elevation effects to the surface will make the overall planet look better.

Title: Re: Celestial Objects Thread
Post by: Aardwolf on May 10, 2010, 11:24:06 pm
I provide a model with texture coordinates and it finds what point on that model each texel corresponds to; then it fires a ray from the origin through that point, figures out what color it needs to be, and puts that in the texel.

But in these images the model is just a plane.

Well, it's important to note that the viewpoint is only 1/2 the radius of the planet above the surface, so the visible portion of the surface isn't that big. So although the transition from light to dark may look like it's stretched wider than it ought to be, that might be in part because it's showing up that much bigger.

Blowfish has noticed there's some 'banding' going on in the dark area, which I've determined has to do with the way I'm discretizing the atmosphere. Increasing the minimum number of iterations might provide improvement, but it's the brute-force way to do it, and it seems to slow it down somewhat. That said, so do the normal maps, and the tangent-space math is probably wrong there anyway. Also I've got no texture-filtering, since it's all software and I haven't implemented anything like that. It would probably also make it slower.

If there's going to be much more discussion of this, I might have to start another thread in the programming board. Or be (voluntarily) thread-split. I reckon the images ought to remain here though.
Title: Re: Celestial Objects Thread

Post by: Aardwolf on May 11, 2010, 01:15:01 pm
I've added linear texture filtering. Also, I'm thinking about switching to a height map instead of a tangent-space normal map, and then using the derivative of the height (numerically) to determine the surface normal vectors.

Those were made with Gimp or Photoshop AFAIK, if that's the case then those planets are detailed as they can get.

You could add some surface detail using real textures, overlaying layers and stuff.. it might get a better surface effect, but IMO the first one has a very decent looking surface, not so sure about the second, but the first one looks quite good.

Probably not necessary then if they are just from PNG conversion, but I don't think it'd be difficult to fix those manually.  Even if you just use the clone tool with a small brush.  The 'funky edges' Aard mentioned might be from misaligned layers but I wouldn't know for sure -- just a guess.

In regard to the planets as a whole, they look rather good. :)  I think the terrain, coloration, and level of detail is a bit better on the first one, and I like the lighting angle on the second.  Would look neat with a sun positioned just above it.

More of a possible technique for future planet makers, but I have found a good way to make your base terrain.  Make four layers of solid noise, and set all of them to difference mode. (this can be shortened in GIMP with difference clouds, eliminating the need for layers).  it will look like this:

I bet if you redid that now it could look a lot better.

the rock ball with rings. 1) reminds me of  a planet in Unreal II. 2) looks awesome 3) there is a slight lighting issue on the left side of the planet where the rings go behind the planet, its bright and to me it looks like it should be dark

Hey T-LoW, if you need more textures you can find some nice ones from sites like cgtextures.com and such.  They'll require a bit of work to turn them into planet surfaces, but you seem to have a knack for the trade already.  :yes:

Title: Re: Celestial Objects Thread
Post by: Herra Tohtori on October 13, 2010, 07:43:55 am
I used this (http://www.eso.org/public/images/eso0932a/) as basis.

I Despeckled it to remove local stars from the image (since I didn't want another Sol system, that's already taken care of), run a Gaussian blur filter to smooth it out a bit, rescaled it to 16384x8192.

Then I made a 16384x8192 greyscale noise layer, spherically distorted so that it can be mapped onto a sphere. After that it was a simple matter of using the modified galactic plane map as alpha and colour mask for the greyscale noise layer and adjusting the levels, contrast and brightness to what I felt was appropriate.

Now I have a generic galactic plane texture that I can mix with normal starfield, or nebula textures. I suspect it will be quite useful in the future. :drevil:
Title: Re: Celestial Objects Thread
Post by: Rodo on October 13, 2010, 10:56:57 am
I see, so you mapped a sphere with two versions of the same image to get it done.. nice!
I used the same image a while back to make the a sol skybox, but I left the image as it was and it looked cool, but too bright to be realistic I'm afraid.
This is gonna be used on BP and MVP's a presume right?

We will see how it goes!

The great advantage with current MediaVP standard starfield is, of course, the fact that it's so resource-friendly. It uses a single 2048^2 texture, while this one would use six 2048^2 textures for standard, and six 4096^2 textures for Advanced, so the memory increases are substantial.

It then depends on whether people want to use it, which is a function of how it affects performance and how much it makes things look better than current starfield - currently I haven't checked how it looks in-game.

Mainly, my aim was to make a starfield for Blue Planet that would reduce the background dichotomy between Sol skybox and non-Sol skyboxes. It is somewhat weird to have the galactic plane visible in Sol skybox while other systems in the galaxe lack it. Whether or not it is adopted by MediaVP's will remain to be seen.
Title: Re: Celestial Objects Thread
Post by: Scourge of Ages on October 13, 2010, 01:31:05 pm
More starfield is always welcome! Just throw 'em in and call them into mvadvanced as starfield2 and starfield3 (if those are available).
Do optional things go into the MVPs? Or would you need to release them seperately?
Title: Re: Celestial Objects Thread
Post by: Rodo on October 13, 2010, 01:51:50 pm
Another thing, so you resized the original image... how so? I mean, when you resize an image the result will be... well awkward, and the sizes you are talking about seem astronomic.
I guess you had an already big BIG base image to work on right?, (being best to shrink than to enlarge) IIRC the one I used was 6000 x something.

I used the enlarged image of the galactic plane as an alpha mask and colourization source for a greyscale noise layer. That way, the blurring that results from scaling up the original image is neutralized - all the detail comes from the noise layer, and the enlarged image works only to determine the intensity and colour of the pixels on the noise layer.

Here's an example:

Let's say you have an image of a star cluster or elliptical galaxy, which is very low-res and you want to increase the resolution.

(http://img508.imageshack.us/img508/4716/clusteroriginallowres.png)

It's so low res that no individual stars are shown. However, it gives you the general intensity at different locations, and gradients scale up relatively well, so let's increase the resolution from 64^2 to 512^2:

(http://img229.imageshack.us/img229/8/clusteroriginalupscaled.png)

Now, this is indeed a bit awkward looking. It doesn't look like a star cluster, it looks like a blob.

So I make a noise layer:

(http://img219.imageshack.us/img219/6311/clusternoise.png)

...and apply the enlarged blob as an alpha mask:

(http://img834.imageshack.us/img834/4594/clusternoisealpha.png)

Then I apply the enlarged blob as a colour layer:

(http://img837.imageshack.us/img837/111/clusternoisealphacolour.png)

...and finally I applied the enlarged blob as screen layer, and reduced the opacity of the noise layer to 30%, resulting in this:

(http://img139.imageshack.us/img139/1831/clusterreducednoisescre.png)


At this point it's a matter of calibrating the layers as you like, depending on whether it's an elliptic galaxy (more fuzzy) or a closed cluster (more grainy/noisy as you can see individual stars better).


In a nutshell this is what I did to the galactic plane there.
Title: Re: Celestial Objects Thread
Post by: Rodo on October 13, 2010, 03:41:09 pm
Then the final rendering is a galatic plane resembling the original shape, but with totally random generated starts.

I was originally inspired/trying to make a rendition of Gliese 581g, but halfway through the creation process I changed my mind and ended up making Vasuda Prime instead (at least as I always imagined it to look).

I put up the TGA here (http://www.megaupload.com/?d=6FZ2DWIT) in 10242 resolution too if anyone wants to use it.

Hello everybody. Here's some 'minor' update.
These pics were that big that I had to scale them down to a third of their actual size so I could upload them for free :)

First:
One of saturn's moons. The texture is right from the NASA. So blame them for any blurry spots (maybe I'll fix them later). Rhea (but I'm sure you can use it elswhere in the universe):

Second:
Another gas giant. Don't tell me it looks kinda comic. It looks cool! Period! :mad:

And third (sick of planets):
A dwarf star (you know - that thing that remains when a lightwheight sun like ours kabooms):
(http://s10.directupload.net/images/101223/y4miyaj5.png)

The dwarf star  is pretty cool too, I wonder how that would look in-game...

Outstanding!  Usually people keep it simple for a first planet, but here you've got seas, clouds, atmospheric haze and halo, and even the smaller details like color differences along the coastlines, specular reflection on the water, and a smooth transition to a darker/fainter atmo-glow on the nightside, so I am extremely impressed. :yes:

Title: Re: Celestial Objects Thread
Post by: TopAce on January 11, 2011, 07:17:32 am
Those clouds look familiar. Are you by any chance using a plugin? I did some similar planets with an easy-to-use plugin for Photoshop, and they looked similar to the one you posted there - with an arguable worse atmosphere, however.
Title: Re: Celestial Objects Thread
Post by: Shivan Hunter on January 11, 2011, 09:50:13 am
Clouds are done by using a Solid Noise render in Gimp, then IWarping it (distorting by moving around/rotating areas of the image), then darkening some parts and IWarping again. I then use bumpmap filters to get some more detail, but that may not work as well as I'd hoped.

Here are the same clouds without any shadowing (I used two layers, each bumpmapped from opposite angles, one addition/one subtraction, and then moved the subtraction (shadow) layer over 3 pixels):

(http://img11.imageshack.us/img11/6534/shhabitable2.png)
Title: Re: Celestial Objects Thread
Post by: T-LoW on January 11, 2011, 11:54:07 am
Search for Earth cloudmap - make it a spherical texture - rotate it so you can see enough details beneath its surface.

And maybe bumpmap those islands for more realism :)

Still a very good attempt, Sir :yes:
Title: Re: Celestial Objects Thread
Post by: watsisname on January 11, 2011, 12:17:32 pm
I think the addition blending is making the image too bright overall.  Instead of using addition and subtraction, try making one cloud layer white and the other black (just inverse the color values), put them both as "normal" layers with the black layer below the white one, and then offset the black layer slightly to simulate the shadowing.

Title: Re: Celestial Objects Thread
Post by: Shivan Hunter on January 11, 2011, 02:08:47 pm
I'll see what a cloudmap can do sometime. Sounds good- better than making everything based on solid noise lol

The previous planet was too bright on purpose. I was experimenting with different kinds of atmospheres- it looks better farther off than it does closer up.

Anyway, was bored this morning so I made another- very large terraformed moon, or planet that's been bombarded all over by asteroid impacts. You astronomer types can figure out exactly what it would be, I guess. No clouds this time.

Title: Re: Celestial Objects Thread
Post by: Shivan Hunter on January 11, 2011, 06:46:14 pm
Simple enough. Started with light gray, and used a circular brush of uniform color to darken circular areas. I do this with several different sizes of brush, then use "make seamless" which is crude but effective. Then I copy the image, tile it 2x or 3x on the same image (small tiles), and make it an "overlay". Once I've done this several times to have some truly small craters, I merge all the layers, copy the image, do an edge-detection on the copy so it's lit at only the edges of the more prominent craters, and make that an "addition" filter. THIS IS A HEIGHTMAP- I used it alongside the Solid Noise layer for the terrain, and bumpmapped it for detail once I had merged the layers and fiddled with the colors.

Here's a little progress with my asteroids. I think these are much better than my first try. What I'm going for is rocky craters on top of craters, like real asteroids. I'm going to forge these into pof's so that they can be used with the background. I've included scenes lit from the right, left, behind-top, and behind-bottom. When you mix and rotate you can get a good variety. I guess the next step is to figure out how to make an animated skybox. :wtf:

There's also jpegs of each so it's easier to fred them together. I included the far away-going around the planet asteroid pics too but they don't have an alpha and are not transparent so don't put a nebula behind them.

I was quite happy with my first planet, except that the mountains were rubbish.

for generic/procedural generated mountains you can use layers of filters->render->clouds and one of the options in there depending on the style you want.

otherwise google for rough texture images off the net which you can greyscale and chop up to suite your needs
Title: Re: Celestial Objects Thread
Post by: Herra Tohtori on February 12, 2011, 10:15:33 pm
Render -> Solid Clouds

Set to "turbulent"

let it render

invert

adjust levels as appropriate.

If you want only parts of the height map to have mountains, make another solid cloud layer, adjust its levels, and use it as alpha mask for the actual mountainous height map.

You should end up with something like this:

(http://img810.imageshack.us/img810/6435/mountainrangeheightmap.png)

Which as such doesn't look too impressive, but when you use it as a height map (here simply embossed to show the effect):

(http://img31.imageshack.us/img31/7310/mountainrangeembossed.png)

(watch out for tresher maws, they nest on flat areas)


This can then be overlaid on top of ground texture, which can also be made with gradients from the height map:

(http://img204.imageshack.us/img204/9127/terraintestb.png)


Of course, in a 3D-program you would just use that as a height map (or make a normal map out of it), but making stuff in 2D is also quite interesting.

Herra, you are the master! Thanks!

EDIT: Except that I can't for the life of me figure out how to apply the height map in PS, or if that's even possible. I can get to the first image you posted, but I have no idea how to get the clouds stuff to look like mountains. I'm quite sure that I'm missing something big here.

EDIT AGAIN: I got some sleep, and I think I'm figuring it out. Still, how exactly did you get that awesome effect?

It's called "Bump map" in GIMP...
Title: Re: Celestial Objects Thread
Post by: Scourge of Ages on February 14, 2011, 12:40:01 pm
OK, it's starting to come together. Found a quick bump map tutorial, and I think it's just going to take some experimentation, plus some gymnastics with Lighting Effects and/or the Emboss filter.
Thanks!
Title: Re: Celestial Objects Thread
Post by: Herra Tohtori on February 14, 2011, 12:44:35 pm
What I did was simple Emboss filter on the height map and then put that layer on top of my terrain texture with Grain Merge layer mode on GIMP. Applying the height map as a bumpmap requires using lighting filter which isn't all that great.

I don't have hands-on experience with Photoshop, so I can't help with the detail there.
Title: Re: Celestial Objects Thread
Post by: Scourge of Ages on February 14, 2011, 02:01:38 pm
Ah, I see. I think it should be mostly translatable to PS. I just need to experiment with it a bunch.

EDIT: Here's what I have so far. I think I just need to create a better texture to make the ground, and figure out how to adjust the clouds to make a good map. I'm thinking about creating the clouds in GIMP, and porting them into PS to work with, as the PS clouds don't quite work right for what I'm going for.

EDIT again!: Some time and work later, plus a stock texture I found, and I now have this:

I think you'd be better off generating your own texture.  That stock one just doesn't match well.  Remember, solid noise, plasma, and coloration filters have nearly infinite uses.

EDIT:  Remember when I posted this?

I found a relatively easy way to make Gas Giants in GIMP.  I will post a tutorial shortly.
EDIT:  Maybe not so shortly, but I will eventually.
Well, I haven't made a tutorial, but here's the xcf file if you think that'll help.

So I found a nice starfield, blocked out a spot, and applied a gravitational lens filter. Do you think it looks believable then?

Yeah JPG artifacts are terrible in images with large, smooth gradients like this.  However I don't think that's a problem with .tga format (correct me if I'm wrong).  Now if you're referring to the banding around the star, that's a side effect of having to use color-to-alpha, and is almost impossible to remove completely.  I went back and cleared that up as best as I can, take a look and see if it's good enough for ya.

Ok, one more request.

There is a way to smooth up the corona gradient (by applying gaussian blur to RGB and Alpha mask separately), but since the flares are integrated to the same layer this will ruin them, for obvious reasons.

Could you upload either a layer containing only the flares, or possibly a layered XCF/PSD file of the star?

It's also possible that I might find an use for the flare layer to enhance the Sunglare skybox further... currently, the sun is confined to a 90 degree wide patch of the sky, which means I can't make stuff like corona elements truly immersive... however, if I had a high quality texture of flares, filaments, protuberances etc. I could make it appear as if they are reaching to, or close to, the orbit where the Indus is stranded at.

It's something that could either work or not, but either way it would be useful.

Ah, thanks, that's a nice trick.  It does limit the ways I can go about merging layers, but at least it should be workable. :)

As for the flares I think the best way to pass them on is to upload the original/unedited fractal flames in png format.  They should be fairly easy to work with.

Post by: FreeSpaceFreak on July 28, 2011, 10:03:19 am
Now trying to make the above planet into a skybox, however running into issues - picture attached. The atmosphere blur doesn't continue seamlessly like the planet does. This is also visible when simply putting the maps next to each other - the planet surface neatly aligns, but the blur doesn't.

The only way I can think of to fix this is to render the atmosphere separate from planet + clouds, then screen atmosphere manually over the planet for each side of the skybox (and its neighbouring sides), then merge the atmosphere layers and blur them as a whole. But having to do this for each face-with-planet would be a pain, and I'm not quite sure if the results would be as expected.

Is there any convenient way to do this?

Title: Re: Celestial Objects Thread
Post by: Rodo on July 28, 2011, 10:18:04 am
wait I don't understand which is the problem, from what I see there you've got a seam... like when you render a skybox with a wrong fov on the camera.

what did you get from the blender render? a simple dds image?, multiple images?, or 6 quadrans like a skybox?
Title: Re: Celestial Objects Thread
Post by: FreeSpaceFreak on July 29, 2011, 03:14:53 pm
I rendered the skybox elements individually with a 90-deg FOV square camera, because Blender's envmap doesn't like compositing nodes.

Well, the obvious solution to blurring issues is to use blur less... also, higher resolution (above at 512, below at 1024, final will be 2048) seems to help. The picture below contains the seam again; can you spot it? And would you notice in-game?

weird, I've made skyboxes before with blurring on the transitions and only detected problems when using a bad fov (which would screw up any image in fact, not only blurry ones) or when I missed to set up the textures for the seamless skybox.

Where's the seam?, that thing far on the left of the image?

EDIT:
just read the spoiler, silly me.
It's not really noticeable, will not be seen in game unless the player sits down a while and looks for it.
Problem with beautiful skyboxes is that people tend to do that unfortunately, btw.. REALLY AWESOME work man.

EDIT 2:
Don't give up, there's definitely a way to get a skybox without seams on it, problem must be somewhere down the line of production.

Hm thanks I were able to see where I went wrong. I checked the "no lighting" box under the skybox flag.

Hm. An Orion isn't visible at 2000 m (ok), and then shows up like boom! in a blue sillouette, which fades to usual mapping as we get nearer (something that would be invisible with no skyboxed nebula).

I'll try with 10k visibility.

Yeah I agree, so I sharpened it up some and rendered it differently and I got this. It's still a little dome like at the top but it's not as bad. There's one more thing I'd like to try before I'm done with this. Maybe remove a lot of those clouds that are moving towards the center. Personally I like this version.

This is supposed to be the upper atmosphere of a gas giant. A ship the size of a Deimos, much less an Orion, has no business being in this environment. Short of a sub space jump I can't imagine how an Orion would even get there.

Yeah well I'm just sayin. Other people could have other ideas and instead of treating your skybox like a giant gas planet, they could interpret it as inside a nebula and try to make capship fights within it.

EDIT: I understand how my comments are getting through, look I think the skybox is amazing and that's why I went to test it ;).

I made both of these a couple years ago, just recently stumbled across them again. The volcanic one was made for ED, then scrapped; the civilized one was originally for now-hibernating EW. Both are in 2048^2 DDS, ready for in-game use. They're not the greatest, but I think they're not too bad either ;)

After roughly a month of work, restarting this thing about three times, constant critiquing from others, frustration, and learning in Photoshop, I present to you all this planet:

(http://dl.dropbox.com/u/18511228/v/Fendaz_Eta_version_black.png)

Below you can download the .psd file if you like. Anyone can use this planet as long as I, Antares Zyklus the 13th (aka Nu Zalem), gets the credit (I'm a fan of open source material *thumbs up*).

.psd file: http://www.mediafire.com/?hn3e3mznd5exh45 (64MB)

Some tidbits about the planet:
- The resolution is at 4096x4096
- I tried to make the darker side of the planet as dark as I could, but I couldn't completely make it black. If anyone has any tips or such then please drop me a line or something.
- The texture for the planet was originally made at 8192x8192 resolution, but I shrank it to 4096x4096
-29 layers in all
- The thing is massive :)

I hope you all put it to use somehow and enjoy it. It was certainly a learning experience for me and has given me confidence to try out new things. I'd like to thank the following for help/advice/criticism: Brand-X, Herratohtori, Zacam, Kyad, Lester^, Bloody Excerment (a friend of mine outside of HLP), FSOSara...if I missed anyone my apologies.

Don't know how to go about doing that atm. If someone explains then I can do it in my spare time or someone else can make it FRED ready. Right now I'm kinda busy with other tasks so I would prefer the latter.

Edit: SDM said something about converting the thing to .dds...I'm not sure if that's all I would need to do though.

Yeah, if i remember right, it would need to be a .dds and then tabled for use. I got a lot of custom skyboxes from others but i'm a little forgetful today. Thanks for the response though =) Perhaps I should try to load it in with Gimp though.

Putting planets in FSO in five easy steps

1. Make sure your planet has a transparent background. The atmosphere (if you have one) should nicely blend into transparency, not cut off anywhere.
2. Save your planet as a square power-of-two-resolution PNG (32 bpp RGBA, if you have the choice).
3. Use nvdxt (download here (http://developer.nvidia.com/legacy-texture-tools)) to convert your file to DDS, options -dxt5 -quality_highest
4. Put the DDS in your mod's /data/effects folder, add the line $BitMapX: <your planet filename, no extension, also not the brackets> to your mod's -str.tbm
5. Profit!

@FreeSpaceFreak:
I think the star brightness, distribution, color, and size are all FANTASTIC, but as a few have mentioned it could use some obscuring dust in there to help make things just a bit more visually interesting.  Faint areas of blue and pinkish nebulosity might be nice, too!

Edit: Just want to emphasize that I'm not recommending any kind of drastic changes -- any additions I can suggest ought to be quite subtle.  What you have currently really is good so I don't think it needs all that much more to make perfect. :)

@T-LoW:
Spiral arms are great, though the glow around the central region is a little overwhelming in my opinion. :nervous:

Guh, those dark nebulas are a *pain* to get right... this is the best I could do so far... For better or worse? Been working on this for so long now that my judgement has gotten obscured x_x

And whatever scaling FSO is using for the skybox sides, it's not very friendly to this, especially around the core.

Title: Re: Celestial Objects Thread
Post by: Herra Tohtori on November 16, 2011, 01:49:17 pm
Is this 2D or 3D?

Regardless of the technique I would try the following things, but execution might vary depending on the technique.


1) reduce cloud altitude
 * looks like you are using a cloud sphere above ground sphere, and a dark version of the clouds as the shadow the same size as the ground. If you make the cloud layer closer to the size of

2) reduce cloud shadow darkness
 * it's quite dark, almost black right now. I suggest using the dark cloud layer in Multiply mode if it is in 2D, and reducing its opacity

3) break up the uniformity of the "high clouds".
 *currently, the clouds that are casting shadows seem quite uniform white, and have very sharp edges. This is sort of hard to address, but I would suggest careful application of blur and smudge brushes, or something. The problem with these uniform white blobs is that they look more like glaciers floating in air, than clouds.

3) make water a darker blue and reduce sun glare gradient size on water
* water is a rather dark blue colour except where sunlight is directly reflected, and the specular reflection size is quite small.

4) reduce thickness of the atmosphere around the planetary edge, but make it reach "in" over the planet a bit more.
* atmospheric effect is what makes earth-like planets blue. It tends to add a a slightly bluish tint to areas toward the "horizon" (the edge of the visible area).
* the atmospheric glow should reach up to like 100-150 km maybe. It is much thinner band around the planet than people usually start with.
* this is usually because people use ubiquitous Low Earth Orbit photography as the "model" of what they wish to achieve; at low altitude, the atmo glow is quite prevalent and thick, but as you move away further into space, it gets progressively thinner (and hard to balance in 2D art; 3D model is usually easier to do by virtue of having the scale of the atmosphere built-in (though it depends on the technique you make it with)

5. add variety to terrain colouration
* currently seems like mix of greens and drab brown/tan colours
* try adding some different greens for different types of vegetation. Northern forests are usually less saturated green than the lush rainforests on the equator.
* also different sort of deserts (Sahara for example looks like mixes of yellow and reddish or slightly orange sand)
* mountain ranges (greyish brown) with snow covered tops and green valleys

6. Reduce the bump mapping slightly
* in high orbit shots, everything except largest elevation variations (mountain ranges) typically look rather flat. It's easy to be overzealous with height mapping the planet.

7. increase resolution of base textures
* this is always a good idea IMHO - go as high as you comfortably can. What sort of textures are you using anyway? How are you making them?



Note that these are representative of what I think a planet should look like. Don't go out of your way to make the planet look like something you don't want it to look like. That said, the listed things are something you might want to experiment with to find what they do to the overall :)

Post by: FreeSpaceFreak on November 16, 2011, 03:52:02 pm
Good work on the colours and the land texture! The clouds, however, look too solid in many areas, the full-white areas don't do justice to the planet.

Maybe a little bit of blue or yellow color in the city lights? They look very... monochrome.
Title: Re: Celestial Objects Thread
Post by: Herra Tohtori on December 29, 2011, 08:56:47 am
What you'll probably want to do is to make a spherical texture of noise, and use the city light texture as a layer mask for that to create a sort of more detailed appearance of the sea of lights.

Current one is a bit jarring because of the large, solidly lit areas as well as overall brightness. Adjusting their colour and masking them on daylight side are also good suggestions. Sodium vapour lights are the most commonly used methods of lighting up outside areas, and they produce distinctly yellow light.

However you could probably do that with render layers and nodes; I'm assuming 3DS Max supports a feature similar to the render nodes in Blender (which is pretty awesome by the way).

Individual cloud formations look slightly large, maybe. Terrain texture is quite nice.

With water, you could try using very dark blue water, almost black but not quite. Something like #0a0a20 or even #08081a could be suitable water colour in the diffuse texture. The overall blueness then comes from atmospheric scattering.

Alright peeps, I spent a good deal of time creating this using Apophysis. I did more than pick a random flame, a random gradient, and rendered it - I did a bunch of transform edits from a blank flame and played around with some settings. Once I got what I liked I rendered it at the highest quality the program would allow...which took well over three hours even with my rig (which is astounding IMO). Below is the pic:

Apophysis is indeed awesome, one of my favorite art-related programs.  Nice to see another user. :)

Best way to improve is simply to play around in it as much as you can, as sometimes awesome results just sort of pop out of nowhere.  Also, try tutorials.  Lots and lots of tutorials.  There's a few on the main site, and many more on DeviantArt which can be really good.

Your fractal flame there looks like it could be a great start for a nebula.  With a few modifications to the transforms (generally I have good luck with the sphericals) and gradient, I think it could be made into a really epic nebula. :yes:

That looks very compelling indeed. As a raw output from a program, it's almost perfect - the only thing I would want to meddle with is that it looks somewhat like an oil painting. That could be quite easily addressed in GIMP or any other image editor with layer modes, however.

Another thing I have noticed is that you should always have a starfield on the background of nebulas when you're working on the final tuning. It helps immensely in putting the object in context; I find it difficulty to gauge the brightness and saturation of the nebulas correctly without a starfield on the background.

How did you...?  *DLs apophysis* I have got to figure this out...
Title: Re: Celestial Objects Thread
Post by: watsisname on February 01, 2012, 01:45:38 am
I really do highly recommend it, like Antares said.  Give it a whirl and see what you can make!

PRE-POST EDIT:  This post got huge, read on if you want to read my inadvertent introduction to Apophysis and nebula-making.

If you'd like to try something nebula-like, the following settings are a good start:
Go to options (Ctrl+P)

-Random tab:   3 to 5 transforms, 2 to 5 mutation transforms, no symmetry.

-Variations tab:  Check Spherical only.  (Other variations can lead to interesting effects so don't be afraid to experiment with combinations of things, but for nebulae I have most luck most often with just spherical -- the other variations can tend to produce sharp boundaries which obviously don't look great on a nebula.)

Gradient:  Either set to random preset if you want the program to randomly use gradients that come with it by default, or use randomize if you'd like it to randomly create new ones using the settings on the right.  You'll have more control over the gradient in the gradient window (F6) afterward.

Then make a batch (Ctrl+B).  Usually I use a batch size of 25, you can set under the Random tab described above.  Scroll through the previews on the left and see if any of 'em suit your fancy.  If not make a new batch.

When you find one you like, you can manipulate it using either the triangle editor (F4) or the mutation editor (F7).  New users will probably find it easier to use the mutation editor at first, but the triangle editor will give you far more control over all aspects of the fractal.  For nebulae, I tend to use both -- I start with mutations to more easily get a nebula-like flame, then use the triangle editor to fine tune it to my liking.

Mutation Editor:  Set the speed low (0.5 to 0.15, perhaps), and make sure the trend is set to spherical.  The default is random which will do god-knows-what to your fractal.  Then the way the mutations work is sort of like artificial selection -- you'll see 9 previews of your fractal, the center one is the way it looks currently, while the ones on the edges are after applying some randomization to it.  If you click the center image, it will keep the fractal the same and make a new set of mutations to look through.  If you see one you like, click it, and it will make that change and create a new set of mutations.  In theory, if you keep clicking the mutations you like, your fractal will gradually become better.  In practice, this sometimes works really well, and sometimes it just never seems to cooperate, as if every possible mutation makes the fractal worse.  And don't freak out if you click a mutation and don't like the change it made.  Just hit the undo button.  If your experience with Apo is anything like mine then you'll become best friends with the undo button very quickly. :P

Triangle Editor:
If you're giving this one a go, then good for you.  It might look very intimidating at first, but I guarantee if you stick with it the results will be worth it.  Unfortunately there is no way I can make a tutorial for how to make a better fractal this way -- you simply have to experiment.  What I can do is tell you what the features are and how to use them.
-The big black grid:  Each transform is represented on the grid as a triangle.  Expand, contract, drag, or rotate a triangle, and the fractal will change accordingly.  With practice you may start to get an intuitive sense for what kind of adjustment will do what kind of change to your fractal.
-You can add, copy, or remove triangles to increase or reduce complexity.
-The 'Weight' of the transform determines how much that particular transform will factor in to the overall shape of the fractal.
-Triangle tab:  A different means of manipulating the triangles (as opposed to clicking/dragging on the grid) -- this tab treats a triangle as an entire entity.
-Transform tab:  More means of manipulating the triangles -- this tab treats each point of a triangle individually.
-Variations tab:  Allows you to directly control how much of each variation goes into each transform.
-Variables tab:  I don't suggest messing around in this one -- that's for very advanced types of fractals.
-Colors tab:  Gives you a huge amount of control over how the color gradient is applied to each portion of the fractal.
-Xaos:  I've never messed with this, I don't know what it does exactly.

That's it for the triangle editor, the other two important editors are:

Adjustment (F5):  I think this one is pretty self-explanatory when you look at it.  One thing that might not be so obvious is the relationship between scale and zoom.  Basically, zoom doesn't affect the overall quality of the fractal.  Scale does.  So it's a give and take:  If you want to expand the fractal, increasing the zoom will increase the amount of detail, but will also increase the rendering time.  Scale will expand it without increasing the rendering time, but will sacrifice the fine detail.


Gradient (F6):  This controls the color.  You can select a gradient from the presets or make your own, either randomly (right click the gradient, select randomize -- this uses the settings under the options > random tab), or make apophysis create one from an image by 'blending' it (the smooth palette button at bottom right).  You can also adjust the hue, saturation, contrast, etc of the gradient in this window.  In short, you can do a lot here.  There's no excuse for not having a kickass gradient to go with your kickass fractal. :D

Lastly, the Render Tab (Ctrl+R):  This is also fairly self explanatory.  You can control the size of the render, its quality (higher quality = more rendering time!) and the format of the created image (you can even save it as .png with transparent background -- great for editing it further in GIMP and the like to make a nebula!)

One last thing -- before rendering a fractal, try hitting F3.  This will very quickly draw up a render for you in fullscreen.  You can hit F3 again and again to render more and increase the detail.  Great if you really want to see the fractal in high detail before investing the time to make an actual render.

That's it.  Good luck and post results! :)

Did a bunch of nebulas in GIMP.

You can download the XCF file here:

http://www.mediafire.com/?1mp9zkshkf9uux8 (http://www.mediafire.com/?1mp9zkshkf9uux8)

The idea is that this big file contains a bunch of more or less isolated nebulas and you can pick them from there, place them in skyboxes you make, or make nebula bitmaps out of them, or just try out how the layers interact and what different layer modes do. There are basically two diffuse emission nebula layers, one dark dust nebula layer, glow layers for the dark nebulas, striation texture for the nebulas (string-like structures in the gas), glows for the stars inside certain nebulas, and of course the starfield itself.

Here are a few more individual nebulae selected from the file.

You're right, Herra, adding a starfield behind them really does make a difference!

Also, those look fantastic, love the Bok Globule / Dark Nebula effect you put in front of some of 'em. :) :yes:


edit:  Nebula I'd posted earlier in the other thread, with a simple starfield added.  Feel free to alter or use as you see fit.

Interesting. I can see your starfield looks much more like the starfields that are typically present in actual scientific astrophotography, with stars of varying sizes. That looks very good if you want to create a photograph-like image!

By comparison my starfield is optimized for producing crisp graphics for in-game (and other) purposes, with mainly single pixel sized stars, and brightness variations produced by RGB intensity in stead of diameter.

Basically, what I noticed long time ago is that stars that are larger than one pixel in diameter have a tendency to blur outrageously if the texture is upscaled, while single-pixel stars have a much more benign behaviour in such a case. However, your starfield looks really cool and quite photorealistic for an image that is supposed to look like a photo. ;)

Did you make the starfield procedurally or use some source imagery?

Post by: watsisname on February 03, 2012, 12:47:06 pm
No source imagery -- all procedurally done in GIMP.  I started with a noise layer, then copied it into several layers while adjusting the curves and adding blur so that larger/brighter stars would be generated with less frequency than the smaller/fainter ones. :)

I hadn't managed to add convincing coloration to it yet, though.  I may need to borrow your method! :D

Beefed up the latest apo fractal, plus some editting in GIMP.  It now has BEAMS, so it's about 20% cooler. :cool:

Yeah, completely random noise.  The entire process was HT's discovery.  mine looks like crap cause it was done in low res, and then scaled up.  You can imagine how it would look done correctly.  Which is what I am working on even as I write this.  Well, actually, I'm writing the tutorial for it, but the only way to do a proper tutorial is to go through it, and explain each step.

That's exactly what you do restof.


This tileable, so you make a blank image at 8192^2, put a copy of the image in each quadrant, then take what you want and turn them into nebulae.

The tut for making these sheets is in modding.

Yep, that's what I had in mind when I designed the workflow.

For making a skybox out of it, the simplest way is to make two hemispheric maps, draw a circle on them, then just lasso and drop nebulas into the circle. After you have enough nebulas in the ring, you apply Polar coordinates filter in GIMP and you get a nice spherically distorted map, which you can then use in Blender to apply to a sphere, and the nebulas will then be rendered to a skybox.

Simple as pi.

I haven't done this myself for some time now, the images I posted are two or three years old, I'd have to familiarize with the matter again if I were to make something like these now. But as I learned of the freespace modding community (and especially of 'Fate of the Galaxy') I thought maybe someone could use them.

Well, I lost the Blender-Files for the two planets so you'd have to take the images as they are. Concernig the sun, I'm just rerendering the image sequence, the animation is now looping, probably better suited for an animated texture. I just don't know, should I render them with an alpha channel and translucent background or with a black background (as it is now)? Also, is the Freespace-Engine capable to use this animation? It consists of 1132 frames, each 750x750 pixels. When the image sequence is useful as an texture I will upload it to a file hosting service.

Alpha Channel, please.

Also, is the Freespace-Engine capable to use this animation? It consists of 1132 frames, each 750x750 pixels. When the image sequence is useful as an texture I will upload it to a file hosting service.

Nope. First things first: image dimensions need to be in powers of 2 (512x512, 1024x1024, 2048x2048 etc). Secondly, I believe that 1132 frames' worth of memory would kill most low-end rigs, and probably some of the higher-end ones. Not sure about that though - ask around.
Title: Re: Celestial Objects Thread
Post by: 3,14 on March 30, 2012, 01:40:32 pm
OK, so I'll have to shorten it a bit and rerender once again. That could take some time though, as there are a lot of parameters to adjust and I don't know how much time I'll have to spend in the next weeks and months. I'll try to work on it but I can't promise anything.
Title: Re: Celestial Objects Thread
Post by: 3,14 on April 02, 2012, 10:26:57 am
OK, so I shortened the animation to 500 frames (even shorter and it would get completely uninteresting I think). The image size is now 512x512 pixels and I rendered them with an alpha channel.
Here you are (if there is interest I can also render a longer and bigger version, like here: http://vimeo.com/38826513 ):
http://www.filehosting.at/file/details/327076/Sun.zip
I think it looks best when viewed around 10 frames a second.
Concerning the planets, as I said, the Blend-files are lost but I think it can't be too difficult for anyone to cut or resize them and add an alpha channel.

Hmm, the tiling is quite noticeable, and you have some weird artifacts around the terminator (especially near the south pole). But the overall colours and mood are very well chosen :yes: No rivers/lakes/oceans anywhere?
Title: Re: Celestial Objects Thread
Post by: BlasterNT on April 25, 2012, 01:44:46 pm
Thanks!

Yeah, my plan is eventually to be able to make every tile unique, this was more of a test to see if the overall effect works.  Should be relatively quick after I get a couple of photoshop actions set up, and the tiles are noisy enough that they appear seamless without any special work.  When I get to it, a unified transit network should break up the tiling as well. 

Not sure what is causing the artifacts, I'll look into that some more. 

Rivers and lakes are present, just all underground.  Perhaps a surface lake here or there, but I'll get to that.  Planning on adding some polar caps as well.

Title: Re: Celestial Objects Thread
Post by: Droid803 on April 25, 2012, 11:51:34 pm
maybe you could paint some larger arcs of lights over top (ie coruscant) to "hide" the tiling? (then again I'm just a sucker for giant circles).
Title: Re: Celestial Objects Thread
Post by: BlasterNT on April 26, 2012, 03:54:28 pm
That's basically what I meant as "transit system".  But I'm also trying to rationalize those circles in a way that makes sense, and I can't think of a way to do so such that they'd contrast/be thick enough to really stand out--I mean, courscant style, you'd basically have almost dark regions to WTFBRIGHT areas, which doesn't really make sense, except as dedicated all daylight zones or something. 

In any case, I think I'm going to go for a more river/circulatory system style of branches of light.

I used max, and followed hoevelkamp's outstanding tutorial here: http://hoevelkamp.deviantart.com/art/3ds-Max-Planet-Tutorial-127582479. 

Only two maps and 4 materials actually.  A base map, which you can get by taking a 1 pixel slice of any old photo (rocks work the best), and stretching it (and I used liquefy and procedural clouds to add a bit of variance), and the NASA blue marble cloud map. 

As for the materials, there's a base, which is just the base map, and two cloudmaps which you can create by setting the base as the diffuse color, and a tiled and stretched cloudmap as the opacity (and bump).  And then just apply the materials to several concentric layers of rotating spheres.

ok I am issuing a Challenge, if we still have people working on random and general celestial objects and starscapes, I have a gauntlet for you.
I am developing a Starfox mod, so I have an interesting dilemna, I am setting up both retro style levels and modern(64) levels, so one of the biggest tricks in the general starscapes, and appropoate celestial objects, so I was hoping I might have someone interested at having a go at it? so I was wondering if you could have a go at a go at making the props for Retro feeling levels, and modern feeling levels

for the retro I am hoping for you to draw directly from the original SF backgrounds, here is a good site for reference http://www.spriters-resource.com/snes/starfox/index.html, mainly space, but I do have the slight challenge of seeing if you can do a starscape based off the venom background that is as if you are in the upper atmosphere of a gas giant(thus still space dynamics), ok so I hope you are willing to go at it, so goodluck, tell me what you think and I do hope I can get a bit more interest in this thread, and get some interesting results you object makers, so farewell, I do hope for some results ;)

oh and SF64 themed levels are welcomed as well, and modernized versions of classic ones as well

The swirls on the texture are made with IWarp filter.

I was bored yesterday, so I took some base textures and made them into three mostly-featureless muns. The first two are only 512^2 and are really only good as muns- the third has an atmosphere and is 1024^2 so it can be used as a planet.

I used this (http://fc00.deviantart.net/fs43/f/2009/084/7/1/metal_texture_13_by_wojtar_stock.jpg) metal texture from google (and another I can't find again), and this (http://i.imgur.com/3brbh.jpg) texture from here (http://webtreats.mysitemyway.com/tileable-burnt-orange-industrial-grunge-textures-part-1/). These kinds of textures can be made into muns/planets very easily- if anyone wants, I'll put up a tutorial.

Each mun/planet has four phases.

Personally I think it would be better to have the shadowed part completely or almost completely black, unless there's plans to add two light sources on the scene from which one would provide the lesser lighting on the dark side.
Aside from that, you kinda nailed it with the textures for the moons.. specially with the first one. The planet looks ok as well, but probably not that interesting because of the repeating pattern on the surface and monochromatic color.
Title: Re: Celestial Objects Thread
Post by: Scourge of Ages on August 07, 2012, 08:55:23 pm
Hey very nice looking planets there, Shivan Hunter!
I think though, that the two moons need a bit more variation in the texture. For the first one, it could be explained by some really stupid huge asteroids just streaking across the surface leaving gouges. But for the second, the long lines on the surface kind of defy any logical explanation and are distracting.

The tutorial I found for these suggested duplicating the base texture a few times, rotating, and then merging them all together again. It breaks up any uniformity and makes 'em look a little more natural.

The planet looks really nice, though I think the perspective/spherize effect could be a little stronger as it currently looks a little too flat along the edges.

It's essentially a mash-up of various tools; the primary one being a Russian space-based engine/simulator which does most of the rendering, with the addition of Nasa's huge maps of various whatnot, with final (and unfortunately, essential) touchups being done by hand in Photoshop.

Another planet, this time up close and personal; tried adding some emphasis to the surface.

DO WANT.
Un-fixable seam issues caused by initial render; don't want. :nono: For some reason each render is several dozen pixels off amongst other things (lighting issues, degrading distance quality,  bla bla etc...)

I was fiddling around with planet rings and decided to try for some ring shadows against the planet. Also, per JCDNWarrior's request, I've uploaded the second skybox (no planets) for public use. It comes with the lossless TGA files and the compressed DDS files (both are at 6*4096x4096 resolution.) Feel free to use as you please; the link is below, instructions are included in the rar file.

Dropbox - MilkyWaySkybox.rar (http://dl.dropbox.com/u/109384068/Skyboxes/MilkyWay2.rar)


Thank you very much, ForeignAnomaly! It looks great - hope to make good use of it in the coming time :) Your most recent update looks incredible as well, and I hope a method could be found to fix the seam issues you mentioned, keep up the good work either way!

You are quite welcome and thank-you; hope it works well in your future endeavors. :yes: It's unlikely that I'll find much time for doing this in the upcoming week, so here's one final one I've finished up (no seam issues finally.) I still liked the other one more, but beggars (such as myself) can't be choosers. :p

For those curious, I recognize the work of Space Engine (http://en.spaceengine.org/) (HLP thread) (http://www.hard-light.net/forums/index.php?topic=76388.0) as the main renderer.  You need a very good machine to run it though.

Indeed. The main issue is you have to fiddle and patch things up via PS (or an equivalent editor) in order for them to get in-game nicely.

I'm figuring out more and more about Freespace and now I'm at this point;  If there is, where do you download planets to use in Fred, and also how do you install them?

You can download them from this very thread. Alternatively, you can check FSMods or other FS related sites ( Top right - External Sites dropdown menu).

To install them, create a folder named "Planets" ( or whatever you prefer), insi9de that folder create a folder named "data".
Inside that folder create two new folders, named "tables" and "effects" ( no quotes).

Place the Planet Bitmaps in the "effects" folder, then create a empty textfile, paste the relevant entries from here (http://www.hard-light.net/wiki/index.php/Stars.tbl), and save as Stars_add.tbm.
Alternatively, extract the Stars_adv tbm from the mediavps, and add the new entries there.
Just make sure you use your own modfolder as described above, and not the FS2 data folder.

When done, open the Launcher and paste this line into the features tab: -mod Planets, or whatever you called your mod.

I've attached an tbm file, edit the entries with notepad (rename the entries in the tbm with the filenames of your bitmaps) and just save it again.

About background stuff...

There's two different ways to put "planets" in a freespace mission.

1) Planet Bitmaps, which are basically image files of the planet itself that you "place" using the FRED2 background editor.
2) Skyboxes, which are 6 images that represent the 6 inner faces of a cube (inside which the mission takes place), this cube is a model that freespace loads up and uses as a far-view fill up.

Which one do you think you'll be using?, Angelus gave a walkthough of the 1st option.


Do as Angelus says first, you'll get to see results faster.
Title: Re: Celestial Objects Thread
Post by: Angelus on October 21, 2012, 12:48:04 pm
skyboxes 'n stuff


There's not much difference in the usage of bitmaps and skyboxes, all it takes is an additional folder within the data folder named "models", where the skybox model is placed.
There are no tbms needed for a skybox though.

And both, bitmaps and skyboxes are set in the background editor in FRED.

Well, I got 2 planets working. I don't know how but I did it.  :D I feel accomplished in some way. Ok do i just save pictures as on these planets and transfer them somehow? ok i believe i now understand how to get them working. now i have another problem. when i put the planets up on the background it does not show up what so ever. what do i do to fix it so i can see the planets?

Gimp with DDS plugin and the ATI Compressionator ( which is free and doesn't require you to have a ATI card).

Seems like transparency issues, or maybe resolution/compression.

I take it this is a bitmap right?, DDS? PNG?, Resolution?
Title: Re: Celestial Objects Thread
Post by: ShadowWolf_IH on October 24, 2012, 10:50:30 pm
png, but it does it when i add the  original xcf as well
Title: Re: Celestial Objects Thread
Post by: Rodo on October 24, 2012, 11:09:40 pm
the xcf has the same artifacts on the borders?

Then the image is the problem, it could have been caused by you scaling it or something like that.

Also, there seems to be some kind of problem with the transparency of the image, I can see stars through the planet.

If you are using Gimp I recommend you to play around with the Map to Object option (not sure if that was the name) under the filter->map options, that will deliver a Sphere with all lighting already done.

The bright lines N/E: very likely caused by blurring up to the edge of the image. I suspect they're there S/E as well, just dark. To prevent this from happening, leave some pixels margin between your planet and the image edge when you blur the atmosphere. The effect is aggravated by what seems to be a low resolution of the planet bitmap; the minimum you'll need for in-game niceness is 1024x1024, but 2048x2048 is preferred. 4096x4096 is even better, but some graphics cards can't support it, so it's more suited for an optional extras-kinda pack.

I thought I would upload this one full size so that you guys could see it.  The planet itself is about 1716 in diameter on a 2048^2 texture.

You might want to tone down the reflection of the planet surface, keep in mind that most planets only reflect enough light to be visible, only cristal/water surfaces should reflect light that intense IMO.

Also, try keeping your dark side always completely dark, unless some other form of lighting is provided for that spot like... vulcanism, or maybe another smaller star.

The surface texture looks nice, and after adding some kind of cloud or atmosphere layer it will probably look better.

All in all, quite good for a second try, mine looked like crap compared to this :P
