Detailed Description

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.).

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, ...).

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.
