Abstract
Techniques are described for transcoding textures which include computing plural endpoint colors for the macroblocks. In a first technique forward Discrete Cosine Transform (DCT) is applied to macroblocks or portions thereof and used to represent the respective portions. In a second technique a mean of the endpoint colors and a difference between the endpoint colors are computed, with the mean and the difference establishing a projection vector in color-space. The mean and the difference are compressed and per-pixel distances along the projection vector are computed and used along with the respective mean and difference to represent the macroblock.
