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.).

Insert/create cell in object by type and list of point ids defining cell topology. Most cells require just a type which implicitly defines a set of points and their ordering. For non-polyhedron cell type, npts is the number of unique points in the cell. pts are the list of global point Ids. For polyhedron cell, a special input format is required. npts is the number of faces in the cell. ptIds is the list of face stream: (numFace0Pts, id1, id2, id3, numFace1Pts,id1, id2, id3, ...)

Get the face stream of a polyhedron cell in the following format: (numCellFaces, numFace0Pts, id1, id2, id3, numFace1Pts,id1, id2, id3, ...). If the requested cell is not a polyhedron, then the standard GetCellPoints is called to return a list of unique point ids (id1, id2, id3, ...).
Get the number of face and the face stream of a polyhedron cell. Result ptIds is in the following format: (numFace0Pts, id1, id2, id3, numFace1Pts,id1, id2, id3, ...).

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.

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.
