Powertek.Rt.PtFastPowShineLUT Class Reference
LookUpTable for Phong/Blinn Shine Calculation Math.Pow(0..1 (always positive), Mat.Shininess (0..200)) We gain approx 10x Performance... def resolution = 1000, means we have a base 0..1 with 3 decimals def maxValue = 200, we can calc exp (Shininess) 0..200 (int steps).
