 | | Section 2.14, Vertex Programs The conventional GL vertex transformation model described in sections 2.10 through 2.13 is a configurable but essentially hard-wired sequence of per-vertex computations based on a canonical set of per-vertex parameters and vertex transformation related state such as transformation matrices, lighting parameters, and texture coordinate generation parameters. |
 | | If a vertex attribute binding matches "vertex.color" or "vertex.color.primary", the "x", "y", "z", and "w" components of the vertex attribute variable are filled with the "r", "g", "b", and "a" components, respectively, of the vertex color. |
 | | If a vertex attribute binding matches "vertex.color.secondary", the "x", "y", "z", and "w" components of the vertex attribute variable are filled with the "r", "g", "b", and "a" components, respectively, of the vertex secondary color. |
