I have completed most of the conversion vertices, polygons and textures etc. I am having trouble with the calculation of the Normal section of the PLY file for the RSD. I have the vertices and the polygon references to the vertices. I have tried the calculate the normal section but without success (Random shading on all the polygons). I have these questions; How do you calculate the Normal section based on the Vertices and Polygon section. Is it a different calculation for guroud (Spelling?!?) and flat shaded polygons. Any help will be appreciated. Ian Thompson
