Was it possible that the "erroneous" vertical lines within the polygons were the hole fracturing lines that I insert if your result type is polygon_concept rather than polygon_with_holes_concept?
The result type is std::list
, polygon_set_concept I think, where polygon_type I defined is polygon_concept.
This small program shows the visual result of 2 polygons clipping, and the resultant ploygons are represented as blue outlines(contours). The input ploygons are taken from Boost.Polygon's unit test, so I would expect the result to be correct at least in this case. But when doing "union", Boost.Polygon shows me the wierd result,* [1]*, seems like all distinct polygons are merged into one contour, while the correct one should be *[2] Screen shots: [1]**http://tinyurl.com/27fwxfn* *[2]http://tinyurl.com/26w3qj6* I'm not sure what's wrong here.
