|
|
* @brief a class that renders hierarchical polygonal data
|
|
*
|
|
* 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 vtkCompositeDataSet built from
|
|
* polydata. If something other than vtkPolyData is encountered,
|
|
* an error message will be produced.
