Abstract

A method and system for optimizing graphics program execution by allowing the sharing of shader resources is disclosed. The method includes accessing a graphics program using a shader pipeline. If a texture projective instruction is included in the graphics program, a determination is made as to whether a texture projective parameter q indicates a non-projective texture. If the texture projective parameter indicates a non-projective texture, the texture projective instruction is demoted and a resulting demoted texture instruction is executed using a plurality of interpolators of the shader pipeline, which requires fewer shader resources.
