ABSTRACT:
Trilinear optimization is a technique to reduce the number of texture samples used to determine a texture value associated with a graphics fragment. Bilinear interpolations replace some trilinear interpolations, thereby reducing the number of texture samples read and simplifying the filter computation. A programmable trilinear slope is used to control replacement of a trilinear computation with a bilinear computation, permitting a user to determine a balance between improved texture map performance and texture filtering quality.
