Texture Mapping with <Image Mapping Functions>
The <Image Mapping Function> indicates which <Image> is being used, how it is combined with any colors the texture-mapped object may have, and so on.
The data provider must specify which of the texture-mapped object’s locations in its own spatial reference frame correspond to various (s, t) points in the <Image>’s frame of reference.
- Most common: <Texture Coordinates> at various <Vertices> of the textured object
