CGAL::Surface_mesh_parameterization::Two_vertices_parameterizer_3< TriangleMesh_ > Class Template Reference

#include <CGAL/Surface_mesh_parameterization/Two_vertices_parameterizer_3.h>

Definition

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.

Public Types

const

Indicate if the border's shape is convex.

Meaningless for free border parameterization algorithms.

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

Map 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<TriangleMesh>::vertex_descriptor as key type and Point_2 (type deduced from TriangleMesh using Kernel_traits) as value type.
VertexIndexMap	must be a model of ReadablePropertyMap with boost::graph_traits<TriangleMesh>::vertex_descriptor as key type and a unique integer as value type.
VertexParameterizedMap	must be a model of ReadWritePropertyMap with boost::graph_traits<TriangleMesh>::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 instanciation of the class VertexUVmap.
vimap	an instanciation of the class VertexIndexMap.
vpmap	an instanciation of the class VertexParameterizedMap.

Precondition

mesh must be a triangular mesh.

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