#include <CGAL/Parameterization_mesh_patch_3.h>

Definition

Parameterization_mesh_patch_3 is a Decorator class to virtually cut a patch in a ParameterizationPatchableMesh_3 3D surface.

Only the patch is exported, making the 3D surface look like a topological disk.

The input mesh can be of any genus, but it has to come with a seam that describes the border of a topological disc. This border may be an actual border of the mesh or a virtual border.

Is Model Of:
ParameterizationMesh_3
Template Parameters
ParameterizationPatchableMesh_33D surface mesh.
Examples:
Surface_mesh_parameterization/Complete_parameterization_example.cpp, Surface_mesh_parameterization/Mesh_cutting_parameterization.cpp, and Surface_mesh_parameterization/polyhedron_ex_parameterization.cpp.

Constructor & Destructor Documentation

template<class ParameterizationPatchableMesh_3 >
template<class InputIterator >
CGAL::Parameterization_mesh_patch_3< ParameterizationPatchableMesh_3 >::Parameterization_mesh_patch_3 ( Adaptor &  mesh,
InputIterator  first_seam_vertex,
InputIterator  end_seam_vertex 
)

Create a Decorator for an existing ParameterizationPatchableMesh_3 mesh.

The input mesh can be of any genus, but it has to come with a seam that describes the border of a topological disc. This border may be an actual border of the mesh or a virtual border.

Precondition
first_seam_vertex -> end_seam_vertex defines the outer seam, i.e. Parameterization_mesh_patch_3 will export the right of the seam.
The seam is given as a container of Adaptor::Vertex_handle elements.
The seam is implicitely a loop. The first vertex must not be duplicated at the end.
