My guess is that you have a problem with the orientation of your faces. The inner surface needs to have its triangles oriented so that their "outside" direction is towards the centre of the vase. If you generate the inner surface using the same code as the outer surface and just change the radius, you will end up with both surfaces oriented outwards, which would produce the effect you describe. -- Greg -- https://mail.python.org/mailman/listinfo/python-list
