Alan,

It works almost like:

	vtkUnstructuredGrid::SetCells(int types, vtkCellArray *cells)

where types could be VTK_QUADRATIC_TETRA for example.


The difference is that you can specify different type, and not only one:

   int types[] = {VTK_QUADRATIC_TETRA, VTK_QUADRATIC_HEXAHEDRON, ...}

If you only have VTK_QUADRATIC_TETRA, then you are better using :

	vtkUnstructuredGrid::SetCells(int types, vtkCellArray *cells)
