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:
