Polyhedron cgal
WebDetailed Description. interface to a 2.5d polygon of arbitrary complexity. The DM polygon object can handle arbitrary nested polygons (often called multi part polygons). The implementation is based on the CGAL nef polygons, a 2d polyhedron representation. Hence, positive regions (=part of the polygon) may contain an arbitrary number of negative ... http://www.cgal.org/
