Rational Bezier Curve Applet
DIRECTIONS:   In this applet, you create a rational Bezier curve, described as
(Σ Bin(t) λipi)/ (Σ Bin(t) λi)
by placing control points pi = (xi,yi) on the screen, which are stored as points in space as (1,xi,yi). The weights λi are initially set as 1, and are modified by using the A and Z keys. The A key decreases the weight and the Z key increases the weight.
