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)

Status

STABLE - used in production
