Detailed Description
A class to draw open uniform cubic B-splines.
A B-spline is a convenient form for representing complicated, smooth curves. A cubic uniform B-spline is a piecewise collection of cubic Bézier curves, connected end to end. A cubic B-spline is C^2 continuous, meaning there is no discontinuities in curvature. B-splines have local control : parameters of a B-spline only affect a small part of the entire spline. A B-spline is qualified as open when it passes through its first and last control points.
