dcel
Dynamic doubly-connected edge list (DCEL) in Rust.
A DCEL is a topological data structure that represents a partition of a surface into easily and quickly traversable vertices, edges, and faces, while making only minimal assumptions about their shapes. You can freely choose wherever the vertices should have two or more dimensions, or wheverer the edges are line segments or curved arcs.
Mathematically, DCEL is an implementation of ribbon graph: a graph where every edge is actually made of two half-edges directed in opposite (aka. darts) that are also cyclically ordered around every vertex, making it possible to rotate around a vertex by following one of them. This in turn also allows circulation around faces (the regions formed by the arrangement of edges). Because of their properties, these cyclic orderings are sometimes called rotations, together forming a rotation system.
