// .NAME vtkGeoTerrain - A 3D terrain model for the globe.
//
// .SECTION Description
// vtkGeoTerrain contains a multi-resolution tree of geometry representing
// the globe. It uses a vtkGeoSource subclass to generate the terrain, such
// as vtkGeoGlobeSource. This source must be set before using the terrain in
// a vtkGeoView. The terrain also contains an AddActors() method which
// will update the set of actors representing the globe given the current
// camera position.
