Polygonize — Find and register all faces defined by topology edges


text Polygonize(varchar toponame);


Register all faces that can be built out a topology edge primitives.

The target topology is assumed to contain no self-intersecting edges.


Already known faces are recognized, so it is safe to call Polygonize multiple times on the same topology.


This function does not use nor set the next_left_edge and next_right_edge fields of the edge table.
