I knew you'd tackle them eventually. It must have been virtually irresistible
for you. :D

project to spur me along the learning curve, and use as a qualification of some
From the "small" of amount of reading I've done, the big difference between
NURBS and Bezier are the basis functions - NURBS control points being much more
local in their effect on the curve. I'm going through Piegl's _The NURBS Book_ -
which is excellent - very thorough, and with code examples.
I'm assuming that for a good modeler, knot insertion, refinement, and removal
would be highly desirable.
I saw a while back that you had started on NURBS, and actually did rational
Bezier - that seemed easy. Did you find it a real challenge to get proper
NURBS working correctly?
Thanks, Jerome :)
