I would really recommend rolling your own NURBS code. Firstly, NURBS are horrible when you don't understand the mechanics behind them, secondly GLU's doesn't do many things one typically needs with NURBS, and thirdly, GLU is a very strange beast that doesn't exist in all GL implementations (or at least is stuck with an old version) and seems to be on the verge of dying out.
Horrible , they realy are.
I have finished "The NURBS Book" chapter 4, and the computation is really complicated. But I will only use order 4 or order 3 spline. Besides I don't need NURBS, I only need uniform B-spline. I will consider your advice, thank you sincerely.
