CGAL 4.10 - Triangulated Surface Mesh Simplification
|
The concept EdgeProfile describes the requirements for a data structure that caches the local topology and geometry in the surroundings of a halfedge.
This profile is used by the stop, cost and placement policies.

The point of vertex v0. | |
| Point const & | p1 () const |
The point of vertex v1. | |
| vertex_descriptor | vL () const |
If v0v1 belongs to a finite face (is not a border edge) the third vertex of that triangular face, a null descriptor otherwise. | |
| halfedge_descriptor | v1_vL () const |

| std::vector< vertex_descriptor > | link () const |

| std::vector< halfedge_descriptor > | border_edges () const |
The unique collection of the border directed edges incident upon v0 and v1. | |
| bool | left_face_exists () const |
Indicates if v0v1 belongs to a finite face of the surface mesh (i.e, v0v1 is not a border edge). | |
| bool | right_face_exists () const |
Indicates if v0v1 belongs to a finite face of the surface mesh (i.e, v1v0 is not a border edge). | |
| const ECM & | surface_mesh () const |
| Returns the surface mesh the edge belongs to. | |
| VertexPointMap | vertex_point_map () const |
| Returns the vertex point property map. | |
| typedef unspecified_type EdgeProfile::ECM |
The type of the surface mesh to simplify.
Must be a model of the EdgeCollapsableSurfaceMesh concept.
| std::vector<vertex_descriptor> EdgeProfile::link | ( | ) | const |
The unique sequence of the vertices around v0v1 in topological order (ccw or cw depending on the relative ordering of v0 and v1 in the profile).
The sequence may have duplicates, but when this happens the edge is not collapsible.
