There is a full OpenGL interface for Mathematica by Conix 
(www.conix3d.com) including Glut. I don't know what you have in mind 
to do, but it would be convenient to have Mathematica functions  (like 
NurbsPlot3D or so) creating
precisely the nurbs objects required by OpenGL. This way one could 
visualize them instantly. I have written a very simple ParametricPlot3D 
substitute creating an OpenGL Quad object with normals
precisely for that purpose. If you're interested, I can you send a 
sample notebook, but you'll need the Conix add-on to try it.
