ParameterizationPatchableMesh_3 Concept Reference

Definition

ParameterizationPatchableMesh_3 inherits from concept ParameterizationMesh_3, thus is a concept of a 3D surface mesh.

ParameterizationPatchableMesh_3 adds the ability to support patches and virtual seams. Patches are a subset of a 3D mesh. Virtual seams are the ability to behave exactly as if the surface was cut following a certain path.

This mainly means that: vertices can be tagged as inside or outside the patch to parameterize. the fields specific to parameterizations (index, u, v, is_parameterized) can be set per corner (aka half-edge).

The main purpose of this feature is to allow the Surface_mesh_parameterization package to parameterize any 3D surface by decomposing it as a list of topological disks.

Design Pattern

ParameterizationPatchableMesh_3 is an Adaptor [6] : it changes the interface of a 3D mesh to match the interface expected by class Parameterization_mesh_patch_3.

Refines:

ParameterizationMesh_3

Creation

Construction and destruction are undefined.

Has Models:

Adaptator for Polyhedron_3 is provided: CGAL::Parameterization_polyhedron_adaptor_3<Polyhedron_3_>
