Colophon

PSArborTouch is based on arbor.js, which has the following colophon.

Arbor’s design is heavily influenced by Jeffrey Bernstein’s excellent Traer Physics library for Processing. In addition, much of the brute-force physics code was originally adapted from Dennis Hotson’s springy.js.

The Barnes-Hut n-body implementation is based on Tom Ventimiglia and Kevin Wayne’s vivid description of the algorithm. Thanks to all for such elegantly simple and comprehensible code.
