CGAL::Medial_skeleton< TriangleMesh, GeomTraits > Class Template Reference

#include <CGAL/Variational_medial_axis_sampling.h>

Definition

template<typename TriangleMesh, typename GeomTraits = Default>
class CGAL::Medial_skeleton< TriangleMesh, GeomTraits >

Class representing the medial skeleton of a shape.

This class provides methods to manage and export the medial skeleton of a shape. It stores the medial spheres, edges, and faces of the skeleton.

Template Parameters

TriangleMesh	The type of the triangle mesh representing the shape.
GeomTraits	The geometric traits class used for geometric computations. Default: CGAL::Kernel_traits< boost::property_traits< boost::property_map<TriangleMesh, CGAL::vertex_point_t>::type >::value_type >::Kernel

Examples

Variational_medial_axis/vmas_free_function.cpp.

Accessor Methods
const std::vector< Sphere_3 > &	vertices () const
	returns the container of vertices, where each vertex is a medial sphere (Sphere_3).
const std::vector< std::pair< std::size_t, std::size_t > > &	edges () const
	returns the container of edges, where each edge is represented as a pair of indices in the vertices vector.
const std::vector< std::array< std::size_t, 3 > > &	faces () const
	returns the container of faces, where each face is represented as an array of three indices in the vertices vector.
std::size_t	number_of_vertices () const
	returns the number of vertices in the medial skeleton.
std::size_t	number_of_edges () const
	returns the number of edges in the medial skeleton.
std::size_t	number_of_faces () const
	returns the number of faces in the medial skeleton.
void	clear ()
	clears the data for the medial skeleton.
void	set_data (std::vector< Sphere_3 > &&vertices, std::vector< std::pair< std::size_t, std::size_t > > &&edges, std::vector< std::array< std::size_t, 3 > > &&faces)
	sets the data for the medial skeleton.

set_data()

template<typename TriangleMesh , typename GeomTraits = Default>

void CGAL::Medial_skeleton< TriangleMesh, GeomTraits >::set_data	(	std::vector< Sphere_3 > &&	vertices,
		std::vector< std::pair< std::size_t, std::size_t > > &&	edges,
		std::vector< std::array< std::size_t, 3 > > &&	faces
	)

sets the data for the medial skeleton.

Parameters

vertices	A list of Sphere_3 representing the vertices (medial spheres).
edges	A list of pairs representing the edges, where each pair contains indices of vertices.
faces	A list of arrays representing the faces, where each array contains three indices of vertices.
