Hello everyone!

I look at “FitCrv” command, the knot spacing in resulting curve is based on the curvature of the input curve, knots are closer together in areas of higher curvature.

I want to know how to make the knots closer together in areas of higher curvature. What are the rules or mathematical algorithms? Is there anyone who can help me ? Thanks!

If I know the principle, the nurbscurve is a parametric equation, I can set the spacing of parameter closer together in areas of higher curvature, then divide points on a curve according to the parameter spacing.
