    Interesting. That's a smart idea - POV probably converts most objects
(excepting primitives) to meshes. I'll have to take a look at the source
code (and hope I can understand some of it).
    I'm really not looking for cylinders and the like. I have an object I
happen to like very much. It looks good, even with bicubic patches. It also
takes up a relatively small space (60K as opposed to five megs of
triangles). It just does strange things with the surface normal.

    The answers will come to me yet....
    Thanks again,
