Catmull-Rom Spline Animation
A new online demo is now available, illustrating the animation of a Catmull-Rom spline from beginning to end. The curve is drawn from t=0 to t=1 in an ENTER_FRAME handler. This emulates how the spline might look if it were drawn by hand.
This demo provides a good introduction to working with C-R splines. Studying how the drawing speed varies with knot placement is a subtle introduction to spline parameterization.
Thanks, by the way, to Mario Klingemann for helping test some of the C-R spline methods.
