Does anyone know if it's possible to use ati_envmap_bumpmap on OS X? Apple doesn't list the ati_envmap_bumpmap extension in their database. Does anyone know if or when it will be available? Is there any comparable implementation of EMBM mapping that will work on Radeon 7000-7500 hardware? [Edited by - Erkokite on November 4, 2005 10:12:20 AM]

What effect are you after? Look here for mac support on extensions.

If you are looking for per pixel lighting or bumpmapping you can use the combiner functions and a dot3 normalmap... HTH?

I basically need to perturb the UV coordinates on a per-pixel basis, using a texture to supply the texture displacement vectors.
