- '''OpenGL extension ATI.envmap_bumpmap
-
- Overview (from the spec)
-
- This extension adds environment mapped bump mapping (EMBM) to the GL.
- The method exposed by this extension is to use a dependent texture
- read on a bumpmap (du,dv) texture to offset the texture coordinates
- read into a map on another texture unit. This (du,dv) offset is also
- rotated through a user-specified rotation matrix to get the texture
- coordinates into the appropriate space.
-
- A new texture format is introduced in order for specifying the (du,dv)
- bumpmap texture. This map represents -1 <= du,dv <= 1 offsets to
- be applied to the texture coordinates used to read into the base
- map. Additionally, the (du,dv) offsets are transformed by a rotation
- matrix that this extension allows the user to specify. Further, a
- new color operation is added to EXT_texture_env_combine to specify
- both that bumpmapping is enabled and which texture unit to apply
- the bump offset to.
-
- The official definition of this extension is available here:
