SYSTEM AND METHOD FOR HIGHER LEVEL FILTERING BY COMBINATION OF BILINEAR RESULTS
Abstract:
A method and system for higher level filtering uses a native bilinear filter, typically found in a texture mapper, and combines a plurality of bilinear filter results from the bilinear filter to produce a higher level filtered texel value. A native bilinear filter is operative to generate bilinear filtered texel values by performing a plurality of bilinearly filtered texture fetches using bilinear filter fetch coordinates. The method and system combines the plurality of bilinear filtered texel values with a plurality of weights to generate the higher level filtered texel value.
