- PlanarEmbedding.connect_components(v, w)#
Adds half-edges for (v, w) and (w, v) at some position.
This method should only be called if v and w are in different components, or it might break the embedding. This especially means that if
connect_components(v, w)is called it is not allowed to call
connect_components(w, v)afterwards. The neighbor orientations in both directions are all set correctly after the first call.
