ABSTRACT:
Systems and methods for positioning bilinear texture samples to produce an anisotropically filtered texture mapped pixel may improve texture mapping performance and image quality. The bilinear texture samples are positioned along a major axis of anisotropy to approximate an elliptical footprint, ensuring that the bilinear texture samples span the entire axis of anisotropy without extending beyond the major axis of anisotropy. An additional bilinear texture sample or a pair of additional bilinear texture samples is positioned in the center of the axis of anisotropy dependent on the anisotropic ratio. The additional bilinear texture samples are weighed less than the other bilinear texture samples and all of the bilinear textures samples lie within the anisotropic footprint.
