Heightmaps?

Is it possible for Sauerbraten to support heightmaps (Like the black and white images)?

I know they support something like that if you make it with numbers:

0000
0010
0020
0200
0300

But what about images?

sauerbraten does support heightmaps, if ou mean the depth maps that're applied to textures that use the bump*parallax*world shader

or if you mean height fields
BF has a /brushimport function if you feel like checking it out.
not that it's currently that hard to do a brush :)

Heightmaps are definitely possible mate, take a look at the default textures for some references.
(Assuming you mean specular/parallax mapping)

I forgot to clarify what I meant :P

I mean for level geometry, like give a heightmap texture and have the actual cubes resemble them.

Could BloodFrontier\'s /brushimport feature be used for this?

Well, the way heightmaps work is more like a square around the cursor that "influences" geometry in the pattern of the brush. It's not a direct "pixel for pixel" operation.

What you could do is convert the image to grayscale (or take one of RGB or HSV and use only that for grayscale) and then convert the image into numbers (one number per pixel) and then use that resulting matrix as a brush.

I'm sure you could either find a tool to do this or write one. It wouldn't be hard.

Incidentally, one (or more) of the Sim City games did this to use pre-defined terrain.

Oh, forgot something.

You'd either have to use a really small gridpower or live with a hugely scaled up version.
Either way, you probably won't get the effect you're looking for.

Which is what BF's /brushimport does :P
