Rational Bezier Curve Applet
DIRECTIONS: In this applet, you create a rational
Bezier curve, described as
λipi)/ (Σ Bin(t)
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.
