Hello, The problem is as follows: Given a set of end-points of lines, I wish to identify/reconstruct all the polygons formed by these lines. The available information is: (1) All these lines belong to 1 or more polygons. (2) The polygons may share common edges, vertices or be disjoint. (3) There are no partially overlapping polygons. Only connected ones. [This is only to avoid ambiguity in interpretation.] (4) A polygon may however be completely inside another without sharing any edges. [A "hole"] (5) Polygons may be convex or concave. (6) A polygon may be defined by the sequence of its bounding edges. I would be very grateful if somebody could either suggest some references or a solution to the above. Thank you. -- Vallury Prabhakar -- rustcat@csli.stanford.edu
