how to extract nurbs control points

[themule]

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.

what do you know about this curve? its equation or....?

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.
