The sample RadeonTeapotTexGen uses automatically generated
texture coordinates and lighting maps to light the Utah
Teapot. Automatically generated camera-space normals index
into a diffuse map for diffuse lighting. Automatically
generated camera-space reflection vectors index into a
specular map to add specular highlights. Using three texture
stages, the Radeon® applies both maps as well as a base
texture in a single pass. Ambient lighting can also added
in the same pass as a texture color factor in the diffuse
lighting stage. Figure 1 shows the lit teapot.
See
RadeonTexGen for additional automatic texture coordinate
effects.
