EntangledVertices Cellzilla2D Home


For each edge in a tissue, determine if there are any entangled vertices on it.

A vertex is considered entangled if it falls on a straight edge and is "lonely" in the sense that it is not an endpoint of any edge.


Return Value

EntangledVertices[tissue] returns a list of lists {l1, l2, ..., ln} where n is the number of edges in the tissue; and each sub-list has either the form {}, if there are no entangled vertices, or {i1,i2, ...} listing the vertex numbers of the entangled vertices on that edge.
