Detailed Description

vtTerrainScene provides a container for all of your vtTerrain objects.

It keeps track of which terrain is active, and allows you to switch between terrains if you have more than one. It also creates some of the surrounding environment (sunlight, skydome) which is common to all of the terrains.
