WebDec 1, 2024 · While these contain the same operations, the first will rotate a cube around the origin and then move it by the offset specified for the translate, before finally coloring it red. By contrast, the second sequence … WebOrdinary Boolean set-operations that operate on (linear) polygons, which distinguish between the interior and the boundary of a polygon, are supported by the Planar Nef …
WebThe idea is that the fundamental building blocks of CGAL are under the LGPL because this is a less constraining license which allows more people to build on top of this code without much constraints. This helps making the CGAL design a de-facto standard for geometric code which helps interoperability.

This allows to write to ostreams as std::cout or std::cerr, as well as to std::ostringstream and std::ofstream. The output operator is defined for all classes in the CGAL Kernel and for the class Color (see Section Colors) as well.
