Abstract
An anisotropic filtering technique includes defining pixel elements in two dimensions and defining at least one object having three dimensional surfaces in a three-dimensional model space and storing texel elements in two dimensions defining a texture map bearing a relationship to the three dimensional surfaces of the at least one object. Each pixel element to be texture mapped is divided into a group of sub-pixel elements and the sub-pixel elements are separately texture mapped. The resultant textures of the sub-pixel elements are averaged to obtain a texture for their respective pixel element.
