void OpenMesh::PolyConnectivity::assign_connectivity | ( | const PolyConnectivity & | _other | ) |

inline

assign_connectivity() method.

See ArrayKernel::assign_connectivity() for more details.

Reimplemented in OpenMesh::TriConnectivity.

void OpenMesh::PolyConnectivity::collapse | ( | HalfedgeHandle | _heh | ) |

Halfedge collapse: collapse the from-vertex of halfedge _heh into its to-vertex.

Attention
  Needs vertex/edge/face status attribute in order to delete the items that degenerate.

Note
  The from vertex is marked as deleted while the to vertex will still exist.
  This function does not perform a garbage collection. It only marks degenerate items as deleted.

Attention
  A halfedge collapse may lead to topological inconsistencies. Therefore you should check this using is_collapse_ok().

void OpenMesh::PolyConnectivity::delete_edge | ( | EdgeHandle | _eh,
|  | bool | _delete_isolated_vertices = `true`
| ) |  |

Mark edge (two opposite halfedges) and incident faces deleted.

Resulting isolated vertices are marked deleted if _delete_isolated_vertices is true. Items marked deleted will be removed by garbageCollection().

Attention
  Needs the Attributes::Status attribute for vertices, edges and faces.

void OpenMesh::PolyConnectivity::delete_face | ( | FaceHandle | _fh,
|  | bool | _delete_isolated_vertices = `true`
| ) |  |

Delete face _fh and resulting degenerated empty halfedges as well.

Resultling isolated vertices will be deleted if _delete_isolated_vertices is true.

Attention
  All item will only be marked to be deleted. They will actually be removed by calling garbage_collection().
  Needs the Attributes::Status attribute for vertices, edges and faces.

void OpenMesh::PolyConnectivity::delete_vertex | ( | VertexHandle | _vh,
|  | bool | _delete_isolated_vertices = `true`
| ) |  |

Mark vertex and all incident edges and faces deleted.

Items marked deleted will be removed by garbageCollection().

Attention
  Needs the Attributes::Status attribute for vertices, edges and faces.

ConstEdgeRange OpenMesh::PolyConnectivity::edges | ( |  | ) | const

inline

Returns
  The vertices as a range object suitable for C++11 range based for loops.

ConstFaceRange OpenMesh::PolyConnectivity::faces | ( |  | ) | const

inline

Returns
  The vertices as a range object suitable for C++11 range based for loops.

ConstHalfedgeRange OpenMesh::PolyConnectivity::halfedges | ( |  | ) | const

inline

Returns
  The vertices as a range object suitable for C++11 range based for loops.

PolyConnectivity::HalfedgeHandle OpenMesh::PolyConnectivity::insert_edge | ( | HalfedgeHandle | _prev_heh,
|  | HalfedgeHandle | _next_heh
| ) |  |

Inserts an edge between to_vh(_prev_heh) and from_vh(_next_heh).

A new face is created started at heh0 of the inserted edge and its halfedges loop includes both _prev_heh and _next_heh. If an old face existed which includes the argument halfedges, it is split at the new edge. heh0 is returned.

Note
  assumes _prev_heh and _next_heh are either boundary or pointed to the same face

bool OpenMesh::PolyConnectivity::is_boundary | ( | HalfedgeHandle | _heh | ) | const

inline

Check if the halfedge is at the boundary.

The halfedge is at the boundary, if no face is incident to it.

Parameters

  _heh | HalfedgeHandle to test

Returns
  boundary?

Reimplemented from OpenMesh::ArrayKernel.

bool OpenMesh::PolyConnectivity::is_boundary | ( | EdgeHandle | _eh | ) | const

inline

Is the edge a boundary edge?

Checks it the edge _eh is a boundary edge, i.e. is one of its halfedges a boundary halfedge.

Parameters

  _eh | Edge handle to test

Returns
  boundary?

bool OpenMesh::PolyConnectivity::is_boundary | ( | VertexHandle | _vh | ) | const

inline

Is vertex _vh a boundary vertex ?

Checks if the associated halfedge (which would on a boundary be the outside halfedge), is connected to a face. Which is equivalent, if the vertex is at the boundary of the mesh, as OpenMesh will make sure, that if there is a boundary halfedge at the vertex, the halfedge will be the one which is associated to the vertex.

Parameters

  _vh | VertexHandle to test

Returns
  boundary?

bool OpenMesh::PolyConnectivity::is_boundary | ( | FaceHandle | _fh,
|  | bool | _check_vertex = `false`
| ) |  | const

Check if face is at the boundary.

Is face _fh at boundary, i.e. is one of its edges (or vertices) a boundary edge?

Parameters

  _fh | Check this face
  _check_vertex | If `true`, check the corner vertices of the face, too.

Returns
  boundary?

bool OpenMesh::PolyConnectivity::is_collapse_ok | ( | HalfedgeHandle | _he | ) |

Returns whether collapsing halfedge _heh is ok or would lead to topological inconsistencies.

Attention
  This method need the Attributes::Status attribute and changes the tagged bit.

Reimplemented in OpenMesh::TriConnectivity.

bool OpenMesh::PolyConnectivity::is_manifold | ( | VertexHandle | _vh | ) | const

Is (the mesh at) vertex _vh two-manifold ?

The vertex is non-manifold if more than one gap exists, i.e. more than one outgoing boundary halfedge. If (at least) one boundary halfedge exists, the vertex' halfedge must be a boundary halfedge.

Parameters

  _vh | VertexHandle to test

Returns
  manifold?

bool OpenMesh::PolyConnectivity::is_simple_link | ( | EdgeHandle | _eh | ) | const

return true if the this the only link between the faces adjacent to _eh.

_eh is allowed to be boundary, in which case true is returned iff _eh is the only boundary edge of its ajdacent face.

bool OpenMesh::PolyConnectivity::is_simply_connected | ( | FaceHandle | _fh | ) | const

return true if _fh shares only one edge with all of its adjacent faces.

Boundary is treated as one face, i.e., the function false if _fh has more than one boundary edge.

void OpenMesh::PolyConnectivity::reinsert_edge | ( | EdgeHandle | _eh | ) |

Inverse of remove_edge.

_eh should be the handle of the edge and the vertex and halfedge handles pointed by edge(_eh) should be valid.

PolyConnectivity::FaceHandle OpenMesh::PolyConnectivity::remove_edge | ( | EdgeHandle | _eh | ) |

Removes the edge _eh.

Its adjacent faces are merged. _eh and one of the adjacent faces are set deleted. The handle of the remaining face is returned (InvalidFaceHandle is returned if _eh is a boundary edge).

Precondition
  is_simple_link(_eh). This ensures that there are no hole faces or isolated vertices appearing in result of the operation.

Attention
  Needs the Attributes::Status attribute for edges and faces.

Note
  This function does not perform a garbage collection. It only marks items as deleted.

void OpenMesh::PolyConnectivity::split | ( | FaceHandle | _fh,
|  | VertexHandle | _vh
| ) |  |

Face split (= 1-to-n split).

Split an arbitrary face into triangles by connecting each vertex of fh to vh.

Note
  fh will remain valid (it will become one of the triangles)
  the halfedge handles of the new triangles will point to the old halfeges
  The properties of the new faces and all other new primitives will be undefined!

Parameters

  _fh | Face handle that should be splitted
  _vh | Vertex handle of the new vertex that will be inserted in the face

Reimplemented in OpenMesh::TriConnectivity.
