Detailed Description

This class defines a Bezier spline in 2D space that passes through a set of given points (called knots). All z values for the knots are set to 0, this will affect all PVector objects used to construct a spline knots.

The curve between each pair of points is a cubic Bezier curve and the controls points are calculated to give a smooth transition along the spline.

The position along the spline can be found using a parametric variable in the range ≥0 and ≤1

Based on source code found on the Internet and modified by the author to work directly with Processing. The URL for the original code has been lost).
