Actually I am working on some algorithm . Taking a seed point on the surface of a polygon. And propagate it considering the linked vertives. Suppose, v1 is my seed point. It has edge with v2, v3, v4 and so on. Next I am considering the link vertices of v2, v3, v4. Next iteration considering their links and so on. Now when viewed the behaviour of propagation of a seed point, it seems at some stage of iteration, some outermost layer points meet and forms a closed edge. Definitely one or a few of the outermost layer form a closed edge. I need to know at what stage the closed edgeis formed to avoid further iteration.
Thanks for any further suggestion. Pls ask me if needs further clarification.
