collision detection - C++ library for mesh to mesh intersection: what is available? -

-
i need calculate volume intersection , penetration depth between 3d triangular meshes (e.g. in .obj format), quite new computational geometry. in previous post ( mesh mesh intersections ) , google search, found few c++ libraries might appropriate job: cgal pqp libigl swift though, not sure 1 appropriate beginner. suggestion? libigl of version 1.1 has robust mesh boolean operations in igl/boolean/mesh_boolean.h . uses either implementation using cgal's exact arithmetic kernel or wrapper of cork (another option you). for now, libigl contains patched version of cork in libigl/external/cork , improves robustness. while implementing libigl's boolean ops, found cork faster not produce correct result (specifically, fails resolve intersections). libigl, using cgal backend, robust , still fast compared converting mesh cgal's nef_polyhedron , conducting csg operations , converting mesh. final conversion possible if result manifold. instead, libigl use...
