Detailed Description

A 2D terrain model for the globe.

vtkGeoTerrain2D contains a multi-resolution tree of geometry representing the globe. It uses a vtkGeoSource subclass to generate the terrain, such as vtkGeoProjectionSource. This source must be set before using the terrain in a vtkGeoView2D. The terrain also contains an AddActors() method which updates the set of actors representing the globe given the current camera position.
