// .NAME vtkMultiGroupPolyDataMapper - a class that renders hierarchical polygonal data
// .SECTION Description
// This class uses a set of vtkPolyDataMappers to render input data
// which may be hierarchical. The input to this mapper may be
// either vtkPolyData or a vtkMultiGroupDataSet built from
// polydata. If something other than vtkPolyData is encountered,
// an error message will be produced.
//
// .SECTION see also
// vtkPolyDataMapper
