How does Catmull Rom work with a Bézier curve?

[pspeter3]

This isn’t an issue as much as a question. Every article I’ve read about Catmull Rom interpolates all the points in between but this implementation uses the Bézier curve function on Path2D / Canvas. How does that work? Thank you in advance for your time / explanation.

It's a good question :)

if (that._l01_a > epsilon) {

implements equation (2) of the paper indicated in #18.

Thank you so much! I'll check out the paper.
