virtual

virtual const DtTerrainInterfaceConfig& DtTerrainSourceTracker::configOptions ( ) const

virtual

virtual bool DtTerrainSourceTracker::init ( DtTerrainSourcePager & )

virtual

Called after options are set. Returns false if error.

Reimplemented in DtOsgEarthTerrainSourceTracker, and DtOsgEarthGroundCoverSourceTracker.

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.

Reimplemented in DtOsgEarthTerrainSourceTracker.

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

pure virtual

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

Implemented in DtOsgEarthTerrainSourceTracker, DtBoundingVolumeTerrainSourceTracker, DtOsgEarthGroundCoverSourceTracker, and DtPagedNode2TerrainSourceTracker.

virtual void DtTerrainSourceTracker::pageInData	(	DtPagingMetaDataPtr	metaData,
		DtTerrainPagingGeometryPtr	geometry
	)

pure virtual

Page in data within geometry. Determines which tiles are within the geometry and adds a page in command to myCommandQueue to page in any tiles within the geometry that have not yet been paged in.

Parameters

geometry	The geometry to page in data within.
intersectId	Id to assign to the page in command to seed tileData for newly paged-in tiles.
priority	Priority to use for commands generated by this call.

Implemented in DtOsgEarthTerrainSourceTracker, DtBoundingVolumeTerrainSourceTracker, DtOsgEarthGroundCoverSourceTracker, and DtPagedNode2TerrainSourceTracker.

virtual bool DtTerrainSourceTracker::canPageOutData ( DtTerrainIntersectIDType intersectId )

pure virtual

Implemented in DtOsgEarthTerrainSourceTracker, DtBoundingVolumeTerrainSourceTracker, DtOsgEarthGroundCoverSourceTracker, and DtPagedNode2TerrainSourceTracker.

virtual DtTerrainIntersectIDType DtTerrainSourceTracker::findOldestPagedData ( unsigned int & numTriangles )

pure virtual

Finds the least-recently-used tile and set myOldestPagedObject to it.

Parameters

numTrianglesOut The number of triangles the least-recently-used tileId represents in the collision world.

Returns: The id of the last intersect test for which this tracker's least-recently-used data was necessary.

Implemented in DtOsgEarthTerrainSourceTracker, DtBoundingVolumeTerrainSourceTracker, DtOsgEarthGroundCoverSourceTracker, and DtPagedNode2TerrainSourceTracker.

virtual void DtTerrainSourceTracker::pageOutOldestData ( const int priority )

pure virtual

Adds a page out command for the least-recently-used tileID to myCommandQueue.

Parameters
