Author Topic: Relief Mapping (Read 991 times)

Thanks to taylor, we've had normal mapping since the Xt builds. Along with it, we've had support for reading height maps for a while but the shaders never did anything with them.

So I'm pleased to finally announce some formal height mapping support in Freespace. I've coded relief mapping which will finally allow our models to have raised/depressed occluding surfaces not part of the mesh.

No test data included but maybe Axem can post the test models he gave me here (Or give me permission to share them)

Does that mean that damage decals can now cause depressions in a target's hull?

m!m's screenspace decals write diffuse and normals into the gBuffer, no height data. Getting the same occlusion effect in there might be a bit trickier so that's something I'd have to get back to you on.

I hereby give Swifty S. Swifterson permission to release the test models. (Note to people checking out the Rahu, that isn't quite the final model yet. I have a few small things to change still!)
