| FaceHandle OpenMesh::TriConnectivity::add_face | ( | VertexHandle | _vh0, | |
| VertexHandle | _vh1, | |||
| VertexHandle | _vh2 | |||
| ) | [inline] |
Add and connect a new face.
Create a new face consisting of three vertices provided by the handles. (The vertices have to be already added to the mesh by add_vertex)
| _vh0 | First vertex handle | |
| _vh1 | Second vertex handle | |
| _vh2 | Third vertex handle |
Reimplemented from OpenMesh::PolyConnectivity.

| FaceHandle OpenMesh::TriConnectivity::add_face | ( | const VertexHandle * | _vhandles, | |
| uint | _vhs_size | |||
| ) |
Add and connect a new face.
Create a new face consisting of vertices provided by a handle array. (The vertices have to be already added to the mesh by add_vertex)
| _vhandles | pointer to a sorted list of vertex handles (also defines order in which the vertices are added to the face) | |
| _vhs_size | number of vertex handles in the array |
Reimplemented from OpenMesh::PolyConnectivity.
| FaceHandle OpenMesh::TriConnectivity::add_face | ( | const std::vector< VertexHandle > & | _vhandles | ) | [inline] |
Override OpenMesh::Mesh::PolyMeshT::add_face(). Faces that aren't triangles will be triangulated and added. In this case an invalid face handle will be returned.

| void OpenMesh::TriConnectivity::assign_connectivity | ( | const PolyConnectivity & | _other | ) | [inline] |
assign_connectivity() method. See ArrayKernel::assign_connectivity() for more details.
Reimplemented from OpenMesh::PolyConnectivity.
Definition at line 67 of file TriConnectivity.hh.
| void OpenMesh::TriConnectivity::assign_connectivity | ( | const TriConnectivity & | _other | ) | [inline] |
assign_connectivity() methods. See ArrayKernel::assign_connectivity() for more details. When the source connectivity is not triangles, in addition "fan" connectivity triangulation is performed

| void OpenMesh::TriConnectivity::flip | ( | EdgeHandle | _eh | ) |
Flip edge _eh. Check for topological correctness first using is_flip_ok().

Helper for vertex split.
| bool OpenMesh::TriConnectivity::is_collapse_ok | ( | HalfedgeHandle | _heh | ) |
Returns whether collapsing halfedge _heh is ok or would lead to topological inconsistencies.
| bool OpenMesh::TriConnectivity::is_flip_ok | ( | EdgeHandle | _eh | ) | const |
Check whether flipping _eh is topologically correct.
| static bool OpenMesh::TriConnectivity::is_triangles | ( | ) | [inline, static] |

| VertexHandle OpenMesh::TriConnectivity::opposite_vh | ( | HalfedgeHandle | _heh | ) | const [inline] |
Returns the opposite vertex to the halfedge _heh in the face referenced by _heh returns InvalidVertexHandle if the _heh is boundary
