Member Function Documentation

virtual bool DtOsgEarthBaseGroundCoverSourceTracker::init ( DtTerrainSourcePager & )

pure virtual

Called after options are set. Returns false if error.

Reimplemented from DtTerrainSourceTracker.

Implemented in DtOsgEarthGroundCoverSourceTracker, and DtOsgEarthVegetationLayerSourceTracker.

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

virtual

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

Implements DtTerrainSourceTracker.

virtual void DtOsgEarthBaseGroundCoverSourceTracker::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.

Implements DtTerrainSourceTracker.

Implemented in DtOsgEarthGroundCoverSourceTracker, and DtOsgEarthVegetationLayerSourceTracker.

virtual bool DtOsgEarthBaseGroundCoverSourceTracker::canPageOutData ( DtTerrainIntersectIDType intersectId )

virtual

Implements DtTerrainSourceTracker.

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

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.

Implements DtTerrainSourceTracker.

virtual void DtOsgEarthBaseGroundCoverSourceTracker::addPagedInTile	(	const osgEarth::TileKey &	tilekey,
		const boost::shared_ptr< DtTileData > &	tileData
	)

virtual

Adds a tileId and the corresponding tileData to #myPagedInTiles.

Parameters

tileId	Key for the tileData passed in.
tileData	tileData to create the tileId -> tileData mapping with.

virtual void DtOsgEarthBaseGroundCoverSourceTracker::removePagedInTile ( const osgEarth::TileKey tileKey )

virtual

Removes a tileId and the corresponding tileData from #myPagedInTiles.

virtual void DtOsgEarthBaseGroundCoverSourceTracker::findMissingTiles	(	const DtTerrainPagingGeometryPtr &	geometry,
		DtTileKeyList &	tiles
	)		const

virtual

Find all the tiles that intersect the geometry which are not paged in.

virtual void DtOsgEarthBaseGroundCoverSourceTracker::findPagedInTilesWithinExtent	(	std::vector< osgEarth::TileKey > &	tileKeysPagedIn,
		const osgEarth::GeoExtent &	extent
	)		const

virtual

Finds the TileKeys for all of the Paged in Tiles that intersect the geo extent.

virtual void DtOsgEarthBaseGroundCoverSourceTracker::pageOutOldestData ( const int priority )

pure virtual

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

Parameters

priority Priority to use for commands generated by this call.

Implements DtTerrainSourceTracker.

Implemented in DtOsgEarthGroundCoverSourceTracker, and DtOsgEarthVegetationLayerSourceTracker.

unsigned DtOsgEarthBaseGroundCoverSourceTracker::maxLOD ( ) const

virtual

Return the max lod (for the ground cover it's the actual ground cover lod)

Reimplemented from DtTerrainSourceTracker.

virtual bool DtOsgEarthBaseGroundCoverSourceTracker::findData	(	const DtTerrainPagingGeometry *	geometry,
		std::vector< boost::shared_ptr< DtTileData > > &	data,
