Approximating curve with arc segments

[might]

I want to approximate any curve (a NURBS) with circular arc segments. How can I calculate the sample points to superimpose the arcs onto the curve? Would you please share your ideas?

Why circular arc segments? Would that look a bit strange? I think it's best to use polynome arc segments, splines, etc, in which case you may try any of a large number of methods. For example you may want to take a look at the "Numerical Recipes" on-line books in
