A Ruby gem for creating and analyzing Bézier curves. Allows you to create a Bézier curve by its control points, get specific point on that curve or iterate the curve points by an Enumerator. Inspired by A Primer on Bézier Curves.

> gem install beziercurve
> require 'beziercurve'
> bez = Bezier::Curve.new(Bezier::ControlPoint.new(40, 250), Bezier::ControlPoint.new(50, 150), Bezier::ControlPoint.new(90, 220))
> puts bez.point_on_curve(0.2).x;
45.2
> puts bez.point_on_curve(0.2).y;

or a nicer way:
> bez = Bezier::Curve.new([40, 250], [50, 150], [90, 220])
> puts bez.point_on_curve(0.2).x;
45.2
> puts bez.point_on_curve(0.2).y;
