ABSTRACT:
A system and method for computing anisotropic texture mapping parameters by using approximation techniques reduces the complexity of the calculations needed to perform high quality anisotropic texture filtering. Anisotropic texture mapping parameters that are approximated may be computed using dedicated processing units within a graphics processor, thereby improving anisotropic texture mapping performance. Specifically, the major axis and minor axis of anisotropy are determined and their respective lengths are calculated using approximations. Other anisotropic texture mapping parameters, such as a level of detail for selecting a particular level are computed based on the calculated lengths of the major and minor axes.
