#include <CGAL/Surface_mesh_parameterization/Two_vertices_parameterizer_3.h>

Definition

template<typename TriangleMesh_>
class CGAL::Surface_mesh_parameterization::Two_vertices_parameterizer_3< TriangleMesh_ >

The class Two_vertices_parameterizer_3 parameterizes two extreme vertices of a 3D surface.

This kind of border parameterization is used by free border parameterizations.

Implementation note: To simplify the implementation, the border parameterizer knows only the TriangleMesh class and does not know the parameterization algorithm requirements or the kind of sparse linear system used.

Is model of

Parameterizer_3

Template Parameters

TriangleMesh_

must be a model of FaceGraph.

parameterize()

template<typename TriangleMesh_ >

template<typename VertexUVmap , typename VertexIndexMap , typename VertexParameterizedMap >

Error_code CGAL::Surface_mesh_parameterization::Two_vertices_parameterizer_3< TriangleMesh_ >::parameterize	(	const Triangle_mesh &	mesh,
		halfedge_descriptor	bhd,
		VertexUVmap	uvmap,
		VertexIndexMap	vimap,
		VertexParameterizedMap	vpmap
	)

maps two extreme vertices of the 3D mesh and mark them as parameterized.

Template Parameters

VertexUVmap	must be a model of ReadWritePropertyMap with boost::graph_traits<Triangle_mesh>::vertex_descriptor as key type and Point_2 (type deduced from Triangle_mesh using Kernel_traits) as value type.
VertexIndexMap	must be a model of ReadablePropertyMap with boost::graph_traits<Triangle_mesh>::vertex_descriptor as key type and a unique integer as value type.
VertexParameterizedMap	must be a model of ReadWritePropertyMap with boost::graph_traits<Triangle_mesh>::vertex_descriptor as key type and a Boolean as value type.

Parameters

mesh	a triangulated surface.
bhd	a halfedge descriptor on the boundary of mesh.
uvmap	an instantiation of the class VertexUVmap.
vimap	an instantiation of the class VertexIndexMap.
vpmap	an instantiation of the class VertexParameterizedMap.

Precondition

mesh must be a triangular mesh.

The vertices must be indexed (vimap must be initialized).
