[comp.graphics] NURBS on SG hardware - need help

blake@ccwf.cc.utexas.edu (Blake Freeburg) (02/19/91)

 I need some help using the SG lib on an RS/6000 and drawing a nurbs surface.
Could anyone spare some code to let me see exactly how to implement one?
Please send via email, I will summarize if interested.

You don't need to use the SGI hardware to do this efficiently. Look in
the December issue of Computer Aided Design for the paper Dynamic Rational
B-spline Surfaces by Rogers and Adlum. It's all there for the taking.
