As of Version 7.0, some of the functionality of the Splines Package is now built into the Wolfram Language kernel.
- To use CompositeBezier, you first need to load the Splines Package using Needs["Splines`"].
- A composite Bézier spline is made up of a series of third‐order Bézier curves with continuity. It alternates interpolating points and control points.
- If the number of points given is even, then the last two points are reversed so that the final point is interpolated and the next to last is a control point for the final segment; if odd, then the final vertex is doubled.
