[Angs]

Hello everyone, first time posting here. First, I want to thank the whole community for being awesome.

I recently started replaying the fs2 retail campaign and wasn't pleased with the radar(s), so I decided to dive into the source and make my own. Without further ado, here's what I came up with: The rear mirror radar:



It has the same projection (azimuthal equidistant) as the original 2D radar, but without vertical flattening (for extra math pureness). The rear mirror is the 90 degree cone behind the player. The forward radar has a projection of a cube with the player centered in it for visualization.

If someone is interested in it, I can give the code/build/graphics. Any comments and/or criticism?

[The E]

Code would be appreciated. I like the idea, and it's an option that is missing at the moment, so I definitely would like to check it out.

[Angs]

Here is a patch and a .vp containing the bitmaps. There are some changes to the -orbradar command line switch for testing purposes: it is renamed to -radar and it takes a int parameter: 0 is standard 2D radar, 1 is orb radar and 2 is the new one.

There are two new additional files in the patch, "radar/radarrm.*", which is not reflected in the project files or makefiles, so they probably have to be added manually.

Edit: changed attached awful code to rewrited more modular one

not bad. i rather like this projection.

i should point out that radars are fairly easy to script. i dont see the point of hard coding every potential radar into the game, which it would be far more sane to allow scripted hud gauges (moddable through in hud_gauges.tbl, but defined in lua). of course its easier to get scripters to write c than it is to get modders to write script. screw it, enjoy your feature creep.

[Angs]

Yeah, I agree that it would be best if it would be possible to define the radar without a recompilation of the entire code, but is there a hud_gauges.tbl for the default retail gauges? The wiki article is a little bit vague on the subject and MediaVP doesn't seem to have one. I just put the code in the first place I could think of as I was in a hurry to play the retail game. With a C++ subclass I could reuse almost all code from the standard hud.

[Dragon]

Looks good, I like it.

[Rodo]

cool radar, I'm getting it if that's ok with you.

[chief1983]

An old fork of the SCP codebase, Imperial Alliance, once had a split radar just like like this, except it was symettrical, and they had moved it to the upper left and right corners of the screen, similar to the X-wing games.  Is this dynamic enough that with the right HUD config and bitmap files, that effect could still be achieved?

[z64555]

Do you know if you can add an option that makes the forward radar an N-gon instead of an ellipse? I know of at least 2 projects that have octogonal radar (FringeSpace and maybe Diaspora)

I have an idea of how to do it, but haven't gotten around to playing with the code.

I don't mind at all.

I twiddled "a little bit" with the code, and came up with a nice way to do this. I added a few hudgauges.tbl options to the standard radar for cutoff angle and whether it points forward or backward. The just load as many radars as you want (well, I couldn't image you'd want more than two but..)
Now I can load the radar presented in the first photo without any command line funnyness with

for this one:

Do you know if you can add an option that makes the forward radar an N-gon instead of an ellipse? I know of at least 2 projects that have octogonal radar (FringeSpace and maybe Diaspora)

I have an idea of how to do it, but haven't gotten around to playing with the code.

How would it work? Are the corners cut off or is the circle projected onto the n-gon, so that the distance to blip to real turning distance wouldn't be equal always?

Anyways, here are resources for the radar(s) if someone wants them.

Awesome, looks good functionally.

[JGZinv]

Angs, this is what we're trying to do.  I've got this as a PSD if you want a
better look at it.

I was originally just thinking of constraining them to fit inside the n-gon, but they would still be projected to an ellipse. JGZ's picture shows the hud gauges used for a majority of the craft in FringeSpace, but one faction has an octagon instead of an ellipse.

Sorry I couldn't find a bigger picture... 

All of the faction's radars have 359 degree forward viewing cone... if that makes any sense. The inside ellipse there marks where the target "should" be on the player's screen, but that will be probably done using some texture magic. Edit: Now that I think of it, the actual radar itself may be a 180 degree viewing cone, but everything beyond 180 is constrained to the edges of its nearest projection. I'm just not sure... this is a weird radar to say the least, Lol.

I was also thinking of adding an option to the n-gon so that you could rotate where the vert's would be, so that people could get something like a heptagon with one vertix pointing up, down, left, etc... if they ever wanted to.


Shoot, I really need to find time to code more fun stuff like this.

[JGZinv]

You made a good point, sorry about forgetting the other hud style.

[TwentyPercentCooler]

No welcome beam? Ah well, welcome to HLP, Angs! Is your name related to angstroms, by any chance?

Good work on the radar, I'll actually try this out. For whatever reason, I prefer the 2D radars.

It's just the Bora.
GalSpan all the way.

Well there's also the 'neutral' hud seen in the Mako, but as far as the radar hud goes, it's the same.

I guess Bora just like being different than the rest of Sol space.

Constraining to an ellipse is simpler than a general n-gon. Before scaling and transposing x and y offsets, draw only if abs(x)<cos(pi/8) && abs(y)<cos(pi/8) && abs(x)+abs(y)<(3-sqrt(2))*cos(pi/8).

After watching a few youtube clips, I must agree that it sure is weird

Thank you! And no, not related. (Where I come from those would be called ångströms)
Well in any case, the radar is a mapping of the 3D space to a 2D screen, it's just a matter whether it tries to look 3D. The orb radar is quite ambiguous when something is close to the borders, not to mention that there are almost always two points that are projected to the same place. This gets especially bad with radar icons.

[chief1983]

Really, having two full circles for the radar makes the icons even more attractive to use if you ask me, they have all that radar real estate to use now
