I have a class where you enter control points for a catmull-rom spline, and then it returns a list of points running along the spline.

What points would I need to enter to create a circle?

Determine arc-length of a Catmull-Rom spline

I have a path that is defined by a concatenation of Catmull-Rom splines. I use the static method Vector2.CatmullRom in XNA that allows for interpolation between points with a value going from 0 to 1. Not every spline in this path has the same length. This causes speed differences if I let the weight… >>> More
