The DtSpatialVrfObjectManager is responsible for maintaining a spatial organization of all specified DtSimObjects. Currently, there is an abstract interface, DtSpatialVrfObjectManagerInterface, which is extended by both DtSpatialVrfObjectManager (which uses spatial subdivision) and DtSpatialVrfObjectManagerOctree (which uses DtOctree). Ultimately, DtSpatialVrfObjectManager should be the interface, and the spatial subdivision implementation should be renamed.
Functor for use in enumerating objects that match a given extent. See DtSpatialVrfObjectManagerInterface::visitObjects().
