path2d_catmullrom

Catmull-rom splines


local catmull = require'path2d_catmullrom'

Math for 2D Catmull-Rom splines defined as:

k, x1, y1, x2, y2, x3, y3, x4, y4

catmull.to_bezier3(k, x1, y1, x2, y2, x3, y3, x4, y4) -> x1, y1, x2, y2, x3, y3, x4, y4

Convert a catmull-rom segment to a cubic bezier curve.

catmull.point(t, k, x1, y1, x2, y2, x3, y3, x4, y4) -> x, y

Get the point at time t on a catmull-rom segment.
