Detailed Description

Base class for Terrain Source trackers.

Determines if the necessary data To perform an intersection is currently available. Can also create commands for a DtTerrainSourceTracker to actually perform the paging.

virtual DtTerrainInterfaceConfig& DtTerrainSourceTracker::configOptions ( )

virtual

virtual const DtTerrainInterfaceConfig& DtTerrainSourceTracker::configOptions ( ) const

virtual

virtual bool DtTerrainSourceTracker::init ( DtTerrainSourcePager &  )

virtual

Called after options are set.

Returns false if error.

virtual boost::optional<DtTerrainIntersectOptions::Fidelity> DtTerrainSourceTracker::intersectFidelity ( ) const

virtual

Fidelity that this tracker is configured for.

The default returns an empty optional which means that this tracker will be used for all terrain intersections. If value is returned then this tracker will only be used for intersections which specify that fidelity.

virtual bool DtTerrainSourceTracker::dataAvailable ( DtPagingMetaDataPtr  metaData, DtTerrainPagingGeometryPtr  geometry  )

pure virtual

Returns

True if all data along this chord has been paged in.

Implemented in DtBoundingVolumeTerrainSourceTracker.
