who can recommend some book about NURBS in OPENGL??
The red book will tell you how to use the gluNurbs interface , as for Nurbs maths check out a book on maths for 3D graphics, any of the Foley,Van Damme et al or Alan Watt books cover the subject.
Alternatively have a look at www.gamasutra.com and search these forums. Many posts have been made over the past few years.
btw, gluNurbs is very slow…
