Bézier Splines

Named after Pierre Bézier, Bézier splines are defined by means of Bernstein polynomials (which are named after Sergei Bernstein). A popular method to evaluate Bézier splines at given parameter values is de Casteljau’s algorithm. A very good online resource with many interactive examples is A Primer on Bézier Curves: https://pomax.github.io/bezierinfo/.

A Python implementation is available in the class splines.Bernstein.
