Detailed Description

This is a node visitor class that evaluates a scene graph and instantiates any DtTerrainSourcePager and TerrainSourceTracker subclasses needed for any of the nodes in the scene graph.

Note

This visitor will allocate new DtTerrainSourcePager subclasses, but will not delete them when destroyed. User must get these pointers using instantiatedPager() and delete them when they are done with them.
