i want to compute nurbs control points for a given arbitrary curve, so that i can draw the set of curves as a nurbs surface using the control points in opengl.. the main problem is how to get the control points. once i have the control points representing the curve in the form of nurbs then there is no problem in rendering it in opengl.

please help.

I have the actual points of the curve.. as in like the output of a CT scan or a curve drawn by hand in a drawing tool.
