Abstract
The current invention involves new systems and methods for increasing texture filtering performance by reorganizing a texture sampling order used to read and filter texels when anisotropic filtering is used. Texel read performance is improved for anisotropic filtering by reorganizing texel reads when a texel cache is used. The texel reads are paired based on a major axis alignment in pixel space. The paired texel reads for a pixel footprint may also be ordered to improve texel coherency, thereby improving a texture cache hit rate.
