// .NAME vtkTerrainDataPointPlacer - Place points on terrain data
//
// .SECTION Description
// vtkTerrainDataPointPlacer dictates the placement of points on height field
// data. The class takes as input the list of props that represent the terrain
// in a rendered scene. A height offset can be specified to dicatate the
// placement of points at a certain height above the surface.
//
// .SECTION Usage
// A typical usage of this class is as follows:
// \code
// pointPlacer->AddProp(demActor); // the actor(s) containing the terrain.
// rep->SetPointPlacer(pointPlacer);
// pointPlacer->SetHeightOffset( 100 );
// \endcode
