Ambient, diffuse and specular color characteristics, Phong cooeficient, reflectance, and transparancy. I have the index of refraction (Well, I have to average it, c'est la vie). I have attempted to derive these experimentally, but find the resulting traced image lacking in many ways, and a simulation visualization I am working on requires accuracy. I am using Kalb's 'rayshade' if it affects your responses. Please respond via e-mail if possible. ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ + Mike Macgirvin Relativity Gyroscope Experiment (GP-B) + + mike@relgyro.stanford.edu (36.64.0.50) + ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ Brought to you by Super Global Mega Corp .com
