Freely customizable, iterative nD subdivision curves for open / closed geometries.

Based in principle on:

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

Supplied / implemented subdivision schemes:

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

Chaikin (closed)	Chaikin (open)
