It doesn't appear that there are any threads here dealing on this subject, so I thought I'd start one.

Currently I'm playing around with a pretty nice program called Apophysis, which can be found here:  http://www.apophysis.org/
Here's a few of my own images I've created thus far using Apophysis:

Feather Spiral. (my very first one )


Spiral Fern.


Solar Nebula.  My favorite thus far.


Edit:  Got a new one, crystal flower.



Please feel free to post any fractal art you may have, too.   And comments/suggestions/critcisms are always appreciated.

Hrm, guess nobody else has a big interest in this stuff.  Ah well, it was worth a shot. 
P.S.  Instead of flooding the forum with more pictures, I'll just say that if anyone wants to check out more images, you can find my work at www.watsisname.deviantart.com

The last one looks like it's made out of silk.

Awesome stuff, I didn't notice this thread earlier. Are the first two things Julia sets? I need to play around with that program when I get some more time.

[watsisname]

They're not Julia sets, though Apophysis does have a feature for exploring those, as well.  These are using IFS, (iterated fuction system), where x'=ax+by+e, and y'=cx+dy+f.  (x',y') is the new point plotted in an iteration, (x,y) is the old point, and a,b,c,d,e, and f are all variables which can be modified by the user.  (That's assuming I understand this correctly.)  I find it amazing that such a simple set of equations is able to make such beautiful and detailed pictures.  8)

Scooby:  Hmm, does kind of look like silk, now that you mention it.

[Ashrak]

can you make em in 1600x1200?

[watsisname]

Yeah, no problem.  

Edit:  Ok, here's one in 1600x1200 size.  I'll add more in a bit.

Wow, that's just a linear system? It's interesting because the behavior of linear functions is actually very simple in one complex variable (basically, when a+c=b+d, the attracting set is just a single point), so it looks like a slight change in those parameters causes all that strange behavior.

That just became my new desktop background.

The ideas to post one of your own yes?

Here we go then

(Made with Chaoscape, from a previous thred)




^Click for larger........

[watsisname]

Mmm, very nice. 
Which equation set did you use for that?  I've not encountered shapes like that yet with Chaoscope.

Here's another 1600x1200 for ya.  Call it flame crystal.  Behold the power.  

[Scooby_Doo]

Ohhh that one could almost be used as a weapons effect.

[Ashrak]

cheers keep em coming hehehe

[watsisname]

Hmm, it'd be a bit different from the usual weapons, but maybe with a trail effect and some animation it might look pretty nice, maybe as some kind of shivan laser weapon thingy?  Apophysis has an animation feature, so I'll see if I figure out how to record/save one.

Lately I've tried making some spiraly self-similar fractals... like the ones typically made by fractal artists.  I've got one made but I'm not very happy with it... hopefully I'll get something good done soon, though.

CP:  The basic IFS equation set is that linear system that I posted earlier, and variations can be made with different functions within those sets.  To clarify, a simple example would be the sinusoidal variant, where
V(x,y) = Sin(x), Sin(y)
*I'm guessing they use "V" to mean "Variant"*

[Scooby_Doo]

Don't limit yourself on mere shivan/terran/vas stuff :-)

Which program are you using and is it free? :-P

Could you do more of these cool pics but with more effects toward the  center like this last pic?

[achtung]

Not mine o' course, but still neat.

The program is called apophysis, and it's free to download from the link in my first post.  Another good program is Chaoscope, but that program is a bit different in what it does and how it functions (see my "Chaoscope and possible new warp effect" thread for details and link).  There's quite a few other fractal programs out there, many of which can probably be found with a simple google search.

As for more pics, I'm still trying to get some pretty spiraly stuff... something remotely like this.  I've gotten pretty close, but it ends up a bit fuzzy and I'm attempting to work out how to get it... not fuzzy.

I'll render a "frost crystal" tonight, to go with the "flame crystal" I posted earlier.  Expect that in a few hours.

[CP5670]

There is another such program called XaoS, for making one variable Julia and Mandelbrot type sets. I haven't been able to get it to display anything other than the built-in example functions (maybe I just didn't try hard enough ), but you can move and zoom around in the images in real time, which is quite impressive to watch.

[watsisname]

That sounds like a pretty nice program, and I'll see if I can check it out later when I get a chance.  By real-time zooming, do you mean it's like a click/drag/box thing and it updates to show the boxed area, or is it an actual seamless zoom?  Either way, sounds rather twinky.

Latest piece is finished now, too.  Hope y'all like it.

Umm drunk /and/or/bored at work.....................

[watsisname]

...Aaaand the latest one.  Also my new desktop.


...I'm not obsessed.  Really.
