Hello! I was wondering if anyone had some information on Non-Uniform
Rational-B-Splines (or NURBS as they call them). I am embarking on a
project that will be dealing with them quite a bit and need to locate
some reference material. Most of the stuff that I have found deals with
plain old B-splines, or Bezeir (sp) et al. I have located a copy of
Wayne Tiller's '86 tutorial notes, Micheal E. Mortenson's Geometric
Modeling, Fundementals of Interactive C.G.,  Fujio Yamaguchi's
Curves and Surfaces in C.A.G.D., A survey of curve and surface methods
in CAGD from CAGD written by Wolfgang Boehm (sp) and deBoors bible of
B-splines. Do I have enough guns in my arsenal or is there a 'definitive
reference' on the subject of NURBS? I will also eventually be making 
nice pictures with them (shading et al) and could use a good 'starting
from scratch reference' on how to go about making those nice pictures
that everyone googles at. I've also played with the IGES spec and some
others. I have the basics, but I need info on things like 'blend surface'
and 'fillet surface' et al. All of the difficult and time consuming tasks.
'Intersect NURBS' is another doozy... Thanks for any and all info!!
