Pixel engine

A method and apparatus, in a computer graphics display system, for producing Anisotropic Texture using constant density object space stochastic sampling. The approach of this invention uniformly samples the footprint of the pixel as mapped into a texture array to determine what complete and fractional texels are covered by the pixel's projected footprint. The sample density remains a constant and is determined by the area of the pixel footprint projection in texture space. Due to variations in footprint projections, each pixel may require a different number of samples, but the sample per texel density remains approximately constant. The intensity is the average of the sample points within the footprint.
