what I want to do is to calculate some deviations on a surface and then index them with colors. Is there a possibility to map this color information to a texture, so the computation has to be done only once for each model. The models are pretty big (150.000 - 250.000 verts, calculated in 5x5-matrices)so it takes a certain amount of time after loading the model. I’m looking for a solution for a pretty long time but there is nothing I could use on the web. The other problem is due to the way the data is arranged I always have only the upper point list and the next point list, meaning I can draw the model only in strips. You might imagine this looks crappy when the colors are interpolated.
