If tet 2-3-4-6 exists, return Tuple(v2, v2-v4, v2-v4-v3 v2-v4-v3-v6), otherwise return Tuple(v2, v2-v4, v2-v4-v3, v2-v4-v3-v5). Must exist a valid return (check by link condition user level? should return a invalid tuple if no ears?).

		const TetMesh &	m
	)

static

gather all simplices that are deleted in a collapse

For interior case: The deleted simplices are the one ring tets of the edge AND the one ring faces of the edge AND the edges and faces where one of the endpoint is the tuple vertex and are contained in the deleted faces and the tuple vertex. This is the intersection of the open star of the tuple vertex and the close star of the edge.

For boundary case: Same as above.

Returns: a pair of vector of ids (int64_t) and tuples(tuple)

◆ get_incident_tets_and_faces()

std::tuple< std::vector< Tuple >, std::vector< Tuple > > wmtk::TetMesh::TetMeshOperationExecutor::get_incident_tets_and_faces ( Tuple t )

Get the incident tets and faces for an edge tuple.

Parameters

edge	tuple t (should be m_operating tuple in the operation class)

Returns: std::array<std::vector<Tuple>, 2> array[0] for incident_tets, array[1] for incident_faces. incident_tets.size() == incident_faces.size() if cycle case; incident_tets.size() + 1 == incident_faces.size() if boundary case. incident_tets[i] has face incident_face[(i+incident_faces.size()-1) % incident_faces.size()] and incident_face[i]. The face and tet iterating direction follows the input tuple.

static

gather all simplices that are deleted in a split

The deleted simplices are the one ring tets AND the one ring faces of the edge AND the edge itself. That is, the open star of the edge.

input: tuple(v1, v1-v2, v1-v2-v4, v1-v2-v4-v3) (vertex, edge, face, tet)

This function will return the tuple that has: the same vertex as the input, a new edge along the input edge, a new face on the input face, and a new tet with is half of the input tet. In the illustration it will return Tuple(v_new, v_new-v2, v_new-v2-v4, v_new-v2-v4-v3)
