SYSTEM, APPARATUS AND METHOD FOR PROGRAMMABLE SHADING USING PIXEL SHADERS

摘要

A system, apparatus and method are provided for performing shafer calculation (602) in a graphics pipeline. Initially, a shading calculation (602) is performed in order to generate output. Thereafter, an additional shading calculation (606) involving the output is performed. Such additional shading calculation (606) includes retrieving texture information (604) utilizing the output. Such texture information (604) includes one-dimensional information, three-dimensional information or a cubemap.
