Figuring is a geometry library for math on simple 2D shapes and for Bézier curves. It also has some simple polynomial solvers for functions on Bézier curves.
one = figuring.ConstantA(1)
linear = figuring.LinearAb(2, 1)
quadratic = figuring.Quadratic(3, 2, 1)
cubic = figuring.CubicAbcd(4, 3, 2, 1)
quartic = figuring.QuarticAbcde(5, 4, 3, 2, 1)
For Bézier curves, there is the general ParamCurve, in addition to the Bezier type for Cubic Bézier curves. Many of the figuring functions were informed by Pomax’s A Primer on Bézier Curves.
A bunch of other 2D shapes have been added to the library to round out the functionality, and make it useful for general geometry.
