DIRECTIONS:   In this applet, you create a C⁰ cubic Bezier spline. When you place 3n+1 points, you create n cubic Bezier curves with the four control points p_3i-3, p_3i-2, p_3i-1, and p_3i for i=1,2,...,n defining the each individual Bezier curve. The points p_3i with i=1,2,...,n-1 are referred to sometimes as joint points, as they are where two individual curves are joined together.
