BiArc Applet
DIRECTIONS: In this applet, you create a circular spline
from biarcs. A biarc is a smooth piecewise circular curve created from
two points p_{0} and p_{1} and
tangent vectors v_{0} and v_{1} at
p_{0} and p_{1} respectively. The applet
creates the biarc by placing two pairs of control points. Each pair
defines a point and a tangent vector, with the first giving the point
and the second giving the tangent vector as the vector from the first
point to the second point.
