Member Function Documentation

virtual bool DtOsgEarthGroundCoverSourceTracker::init ( DtTerrainSourcePager & )

virtual

Called after options are set.

Returns false if error.

Reimplemented from DtTerrainSourceTracker.

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

virtual

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

Implements DtTerrainSourceTracker.

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

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.

virtual bool DtOsgEarthGroundCoverSourceTracker::canPageOutData ( DtTerrainIntersectIDType intersectId )

virtual

Implements DtTerrainSourceTracker.

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

virtual

Parameters

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

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