DIRECTIONS:   In this applet, you create a G² Bezier spline by placing control points d_-2, d_-1, d₀, ... d_L to create a curve consisting of L cubic segments. The original curve created is a C² Bezier spline. You can using the move button feature and clicking on one of the points d₀ to d_L-2, adjust the position of control points for individual arcs by using the ratio sliders associated to the control point.
