An apparatus and method for using non-power of two texture maps with anisotropic filtering is described. An anisotropic perturbation is applied to a texture map coordinate to produce a perturbed texture coordinate. A wrapped texture map index for various wrap modes is computed using the perturbed texture coordinate and an LOD width. In addition to the anisotropic perturbation, the perturbed texture coordinate may also include a tap perturbation.
