Orthogonal Hyperedge Routing
Orthogonal connectors are used in drawings of many network diagrams, especially those representing electrical circuits. Such diagrams frequently include hyperedges—single edges that connect more than two endpoints. While many interactive diagram editors provide some form of automatic connector routing we are unaware of any that provide automatic routing for orthogonal hyperedge connectors. We give three algorithms for hyperedge routing in an interactive diagramming editor. The first supports semi-automatic routing in which a route given by the user is improved by local transformations while the other two support fully-automatic routing and are heuristics based on an algorithm used for connector routing in circuit layout.
