Texture Map Blending
Multiple Textures can be blended together in an iterative process and applied to a primitive. The GMCH
allows up to four distinct or shared texture coordinates and texture maps to be specified onto the same
polygon. Also, the GMCH supports a texture coordinate set to access multiple texture maps. State
variables in multiple textures are bound to texture coordinates, texture map or texture blending.
Combining Intrinsic and Specular Color Components
The GMCH allows an independently specified and interpolated “specular RGB” attribute to be added to
the post-texture blended pixel color. This feature provides a full RGB specular highlight to be applied to
a textured surface, permitting a high quality reflective colored lighting effect not available in devices,
which apply texture after the lighting components have been combined. If specular-add state variable is
disabled, only the resultant colors from the map blending are used. If this state variable is enabled, the
specular RGB color is added to the RGB values from the output of the map blending.
