a RandomAccessRange of RandomAccessRange of points. The point type must be from a 3D point from a CGAL Kernel. A polyline is defined as a sequence of points, each pair of contiguous points defines a segment of the polyline. If the first and last points of the polyline are identical, the polyline is closed.
Parameters
polylines1
the first range of polylines to check for intersections.
polylines2
the second range of polylines to check for intersections.
a RandomAccessRange of points. The point type must be from a 3D point type from CGAL Kernel. A polyline is defined as a sequence of points, each pair of contiguous points defines a segment of the polyline. If the first and last points of the polyline are identical, the polyline is closed.
returns true if there exists a face of tm1 and a face of tm2 which intersect, and false otherwise.
If do_overlap_test_of_bounded_sides is set to true, the overlap of bounded sides are tested as well. In that case, the meshes must be closed. This function depends on the package Intersecting Sequences of dD Iso-oriented Boxes.
a RandomAccessRange of RandomAccessRange of points. The point type of the range must be the same as the value type of the vertex point map. A polyline is defined as a sequence of points, each pair of contiguous points defines a segment of the polyline. If the first and last points of the polyline are identical, the polyline is closed.

detects and reports all the pairs of meshes intersecting in a range of triangulated surface meshes.
A pair of meshes intersecting is put in the output iterator out as a std::pair<std::size_t, std::size_t>, each index refering to the index of the triangle mesh in the input range. If do_overlap_test_of_bounded_sides is true, the overlap of bounded sides are tested as well. In that case, the meshes must be closed. This function depends on the package Intersecting Sequences of dD Iso-oriented Boxes.
template<class ConcurrencyTag = Sequential_tag, class TriangleMesh , class FaceRange , class FacePairOutputIterator , class NamedParameters = parameters::Default_named_parameters>
a model of OutputIterator holding objects of type std::pair<boost::graph_traits<TriangleMesh>::face_descriptor, boost::graph_traits<TriangleMesh>::face_descriptor>
Extra: The geometric traits class must be compatible with the vertex point type.
the maximum number of self intersections that will be detected and returned by the function.
Type: unsigned int
Default: No limit.
Extra: In parallel mode, the number of returned self-intersections is at least maximum_number (and not exactly that number) as no strong synchronization is put on threads for performance reasons.
template<class ConcurrencyTag = Sequential_tag, class TriangleMesh , class FacePairOutputIterator , class NamedParameters = CGAL::parameters::Default_named_parameters>
a model of OutputIterator holding objects of type std::pair<boost::graph_traits<TriangleMesh>::face_descriptor, boost::graph_traits<TriangleMesh>::face_descriptor>
output iterator to be filled with all pairs of non-adjacent faces that intersect. In case tmesh contains some degenerate faces, for each degenerate face f a pair (f,f) will be put in out before any other self intersection between non-degenerate faces. These are the only pairs where degenerate faces will be reported.

an optional sequence of Named Parameters among the ones listed below
Optional Named Parameters
a property map associating points to the vertices of tmesh
Type: a class model of ReadWritePropertyMap with boost::graph_traits<TriangleMesh>::vertex_descriptor as key type and Point_3 as value type
Default: boost::get(CGAL::vertex_point, tmesh)
Extra: If this parameter is omitted, an internal property map for CGAL::vertex_point_t should be available for the vertices of tmesh.
Extra: The geometric traits class must be compatible with the vertex point type.
the maximum number of self intersections that will be detected and returned by the function.
Type: unsigned int
Default: No limit.
Extra: In parallel mode, the number of returned self-intersections is at least maximum_number (and not exactly that number) as no strong synchronization is put on threads for performance reasons.
