His algorithm is based on this paper, which imho belongs to a whole class of algorithms called neighbour sensing models.

In this three part tutorial we’ll go over the process of implementing this algorithm in Houdini using VEX and a few built in nodes. Also we’ll talk about why rotation matrices come in handy and how to modify this algorithm to work in 3D sapce.
