Detailed Description

A 3D terrain model for the globe.

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.
