CGAL::Polygon_mesh_slicer< TriangleMesh, Traits, VertexPointMap, AABBTree, UseParallelPlaneOptimization > Class Template Reference
Polygon Mesh Processing Reference

#include <CGAL/Polygon_mesh_slicer.h>

Definition

template<class TriangleMesh, class Traits, class VertexPointMap = typename boost::property_map< TriangleMesh, vertex_point_t>::type, class AABBTree = AABB_tree< AABB_traits<Traits, AABB_halfedge_graph_segment_primitive<TriangleMesh> > >, bool UseParallelPlaneOptimization = true>
class CGAL::Polygon_mesh_slicer< TriangleMesh, Traits, VertexPointMap, AABBTree, UseParallelPlaneOptimization >

Function object that computes the intersection of a plane with a triangulated surface mesh.

Template Parameters
TriangleMesha triangulated surface mesh, model of FaceGraph and HalfedgeListGraph
Traitsa model of AABBGeomTraits
VertexPointMapa model of ReadablePropertyMap with boost::graph_traits<TriangleMesh>::vertex_descriptor as key and Traits::Point_3 as value type. The default is typename boost::property_map< TriangleMesh, vertex_point_t>::type.
AABBTreemust be an instantiation of CGAL::AABB_tree able to handle the edges of TriangleMesh, having its edge_descriptor as primitive id. The default is CGAL::AABB_tree<CGAL::AABB_traits< Traits, CGAL::AABB_halfedge_graph_segment_primitive<TriangleMesh> > >
UseParallelPlaneOptimizationif true, the code will use specific predicates and constructions in case the functor is called with a plane orthogonal to a frame axis, the non-null coefficient being 1 or -1. The default is true.

The implemenation of this class depends on the package 3D Fast Intersection and Distance Computation.

Examples:
Polygon_mesh_processing/mesh_slicer_example.cpp.
