Even so, you might look for "least >squares" in your searches.

I can figure my own forgotten knowledge as an armadillo closed as a hard ball. It's there, but closed and not accesible... <http://www.msu.edu/~nixonjos/armadillo/tolypeutes.html> >It is probably straight forward to draw the curve >once you get a fit, I imagine. Doing the fit is >probably the hard part. You are right, the fit is the hardest part. But, reading again the bezier curve definition I have a hunch that this could be approximated and solved using a more geometric approach. If i can probe that this hunch is right, i'll get back to the list with a demostration for comments and corrections.
