G1 Bezier Spline Applet
DIRECTIONS: In this applet, you create a G1 cubic
Bezier spline, by placing control points and choosing a knot sequence. The applet
functions much like the C1 Bezier spline applet original, as it chooses
the knot sequence as a uniform knot sequence by default (which is exactly the manner
of a C1 Bezier spline. You can modify the knot sequence by using the knot
slider bar at the bottom of the applet. The knot sequence controls the location of
the joint points for the C0 cubic Bezier spline (or composite Bezier curve).
For practical purposes, this means that the joint point is no longer at the midpoint of a
segment, but at a point defined by the knot sequence, which by appropriate choice of a knot
sequence can be located anywhere on the segment.
