Hemesh is an exciting Processing library by Frederik Vanhoutte (W:Blut) that can be used to create elaborate 3D shapes quickly. It is an implementation of the half-edge datastructure, hence the name Hemesh. What makes this datastructure interesting is it’s inherent ability to store connectivity information. So it’s much more than just a list of vertices and faces. Rather it’s about the efficient description of connections between them. This kind of information comes in handy when you want to manipulate, distort and creatively destroy three-dimensional shapes in a sensible manner.
