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.

Return 1 if this class is the same type of (or a subclass of) the named class.

Returns 0 otherwise. This method works in combination with vtkTypeMacro found in vtkSetGet.h.

Methods invoked by print to print information about the object including superclasses.

Typically not called by the user (use Print() instead) but used in the hierarchical print process to combine the output of several classes.

Update the actors in an assembly used to render the globe.

ren is the current renderer, and imageReps holds the collection of vtkGeoAlignedImageRepresentations that will be blended together to form the image on the globe.
