Hello. First I would like to thank all the people who sent me references on
the Platonic solids. They were a fantastic help.

Now I need to know something else ; How does one use NURBS? I have done some
spline programming so hopefully I will be able to understand the math involved.

How does one go about creating the shape that they want using NURBS surfaces
or even NURBS curves? If I have a shape that I want to reproduce, how
do I do it? What kind of data do I need?

Ideally, someone out there has used NURBS surfaces on graPHIGS (IBM's version
of PHIGS with extensions) and could give me a few pointers. I would be perfectly
happy, however, with some pointers to the literature on NURBS surfaces and 
curves (especially surfaces).


Once again, I would like to thank those of you who responded to my previous
postings. And hopefully, I can be of some help to you someday.
