In this applet, you create C2 cubic Bezier splines. These
are created by placing the control points and then generated a piecewise
cubic Bezier curve according to the rules described in the course notes.
Play with creating C2 splines.
What conditions need to satisfied at a joint point in order for two segments to be joined smoothly?
Using C2 splines can you create a curve that is approximately
a circle? If so how?
