Color Distribution - a new approach to texture compression

Texture compression is recently one of the most important topics of 3D scen e rendering techniques, because it allows rendering more complicated high-r esolution scenes. However, because of some special requirements for these t ype of techniques, the commonly used block decomposition approach may intro duce visual degradation of image details due to lack of colors. We present here a new approach to texture compression, which allows sharing of one col or by several blocks providing a larger number of unique colors in each par ticular block and the best compression ratio. We also present an iterative algorithm for obtaining distributed colors on a texture, and discuss some a dvantages of our approach. The paper concludes with comparison of our techn ique with S3TC and other block decomposition methods.
