You ask for an alternative, and there is one within Boost. You might look at Boost.Geometry, which has traits designed differently so maybe this problem will not occur. It is not tested in CodeWarrior though.
Sources are still here https://svn.boost.org/svn/boost/sandbox/ggl/formal_review and at our SVN.
It has the union for polygons with holes.
Have you implemented the multi-polygon interfaces for the union and intersection operations?
Polygons with holes (not being multi-polygons) are there already.
I'm busy with the overlay operations, it is somewhat delayed but the plan was to have it in the sandbox again soon. Including multi's.
Kef didn't specify whether he wanted to merge 2 polygons with holes or N polygons with holes. I would expect it is the latter. Interesting. What do you mean by overlay operations, exactly? Two layer map-overlay or N-layer? Thanks, Luke
