About

Freely customizable, iterative nD subdivision curves for open / closed geometries. This is a support package for @thi.ng/geom.

Based in principle on:

Generating subdivision curves with L−systems on a GPU
Clojure version thi.ng/geom-clj.

Supplied / implemented subdivision schemes:

Split @ midpoints (open / closed)
Split @ thirds (open / closed)
Chaikin (open / closed)
Cubic (closed only)

Chaikin (closed)	Chaikin (open)
