TEXEL SHADING IN TEXTURE SPACE

A graphics processing unit is configured to map pixels of a first frame of a video stream to texels, select a subset of the texels for shading based on previously cached texels that were shaded for a second frame, and shade the subset of the texels. The graphics processing unit is also configured to cache the shaded subset of the texels with the previously cached texels and determine values for the pixels of the first frame based on the cached texels.
