// .NAME vtkHierarchicalPolyDataMapper - 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 vtkHierarchicalDataSet built from
|
|
// polydata. If something other than vtkPolyData is encountered,
|
|
// an error message will be produced.
