dataset represents arbitrary combinations of all possible cell types
vtkUnstructuredGrid is a data object that is a concrete implementation of vtkDataSet. vtkUnstructuredGrid represents any combinations of any cell types. This includes 0D (e.g., points), 1D (e.g., lines, polylines), 2D (e.g., triangles, polygons), and 3D (e.g., hexahedron, tetrahedron, polyhedron, etc.). vtkUnstructuredGrid provides random access to cells, as well as topological information (such as lists of cells using each point).

To handle vtkPolyhedron, use SetPolyhedralCells() SetPolyhedralCells requires a faces vtkCellArray that will describe the faces use by the polyhedral cells. SetPolyhedralCells also requires a faceLocations vtkCellArray to fully describe a polyhedron cell The faceLocations is a collection of face ids pointing to the faces vtkCellArray.

A topological inquiry to determine whether a topological entity (e.g., point, edge, or face) defined by the point ids (ptIds of length npts) is a boundary entity of a specified cell (indicated by cellId).
A boundary entity is a topological feature used by exactly one cell. This method is related to GetCellNeighbors() except that it simply indicates whether a topological feature is boundary - hence the method is faster. THIS METHOD IS THREAD SAFE IF FIRST CALLED FROM A SINGLE THREAD AND THE DATASET IS NOT MODIFIED.

int vtkUnstructuredGrid::InitializeFacesRepresentation | ( | vtkIdType | numPrevCells | ) |
Special function used by vtkUnstructuredGridReader.
By default vtkUnstructuredGrid does not contain face information, which is only used by polyhedron cells. If so far no polyhedron cells have been added, Faces and FaceLocations pointers will be nullptr. In this case, need to initialize the arrays and assign values to the previous non-polyhedron cells.

This time is different from the usual MTime which also takes into account the modification of data arrays. This function can be used to track the changes on the mesh separately from the data arrays (eg. static mesh over time with transient data).

A static method for converting a polyhedron vtkCellArray of format [nCellFaces, nFace0Pts, i, j, k, nFace1Pts, i, j, k, ...] into three components: (1) an integer indicating the number of faces (2) a standard vtkCellArray storing point ids [nCell0Pts, i, j, k] and (3) an vtkIdTypeArray storing face connectivity in format [nFace0Pts, i, j, k, nFace1Pts, i, j, k, ...] Note: input is assumed to contain only one polyhedron cell.
Outputs (2) and (3) will be stacked at the end of the input cellArray and faces. The original data in the input will not be touched.

Special methods specific to vtkUnstructuredGrid for defining the cells composing the dataset.
Most cells require just arrays of cellTypes, cellLocations and cellConnectivities which implicitly define the set of points in each cell and their ordering. In those cases the cellConnectivities are of the format (numFace0Pts, id1, id2, id3, numFace1Pts, id1, id2, id3...). However, some cells like vtkPolyhedron require points plus a list of faces. To handle vtkPolyhedron, SetCells() support a special input cellConnectivities format (numCellFaces, numFace0Pts, id1, id2, id3, numFace1Pts,id1, id2, id3, ...) The functions use vtkPolyhedron::DecomposeAPolyhedronCell() to convert polyhedron cells into standard format.
