piece-wise linear approximation.

For most geometrical Objects this is rather simple to do:

Circle (or segment): just subdivide the Angle (n*2pi/N)

Bezier curves: there is a subdivision algorithm

Rectangles, Polygones: nothing to do.

If those objects exist as a function, you can simply

evaluate those functions for n/N, i.e. f(n/N) and

connect the resulting N+1 points with lines.
