// .NAME vtkRenderedSurfaceRepresentation - Displays a geometric dataset as a surface.
//
// .SECTION Description
// vtkRenderedSurfaceRepresentation is used to show a geometric dataset in a view.
// The representation uses a vtkGeometryFilter to convert the dataset to
// polygonal data (e.g. volumetric data is converted to its external surface).
// The representation may then be added to vtkRenderView.
