class  BRepExtrema_ShapeProximity
 Tool class for shape proximity detection. For two given shapes and given tolerance (offset from the mesh) the algorithm allows to determine whether or not they are overlapped. The algorithm input consists of any shapes which can be decomposed into individual faces (used as basic shape elements). High performance is achieved through the use of existing triangulation of faces. So poly triangulation (with the desired deflection) should already be built. Note that solution is approximate (and corresponds to the deflection used for triangulation). More...
