Detailed Description

This manager is on a per-DtVrfObject level, and is responsible for knowing what terrain areas an object is expected to need in the near future for the purpose of pre-loading that terrain from a server or paged terrain source.

Objects that are part of the DtVrfObject (typically controllers or actuators) register as providers with this object if they with to provide this type of data as input. Providers must add their new geometry (if any) to the geometry list that is passed in as an argument to the callback that is invoked.
