WebOct 23, 2024 · Please clarify what you mean by a "crossing path" There seem to be two possibilities that I can see. A. A crossing path occurs at a vertex with four or more edges. One path uses two edges to enter and leave the vertex, the second path uses a different pair of edges. OR. B. The vertices have x,y locations all in the same plane.
