On the following picture, we have overlapping polygons: we know the positions of vertices and the edges for each polygons, and the intersections are exactly known (vertices at the intersection are represented on the figure). Is it possible to 'partition' the domain spanned by the union of these polygons into 'disjoint' polygons (with contacts only at the boundary)? To be more precise, I'd like to associate to all edges the surfaces for which the edge is contained in its boundary.Please advise if I'm not clear enough and thanks in advance for any suggestions!
