A DtPagedNode2TerrainSourceTracker tracks data from osgEarth pagedNode2 terrain source.

A DtPagedNode2TerrainSourceTracker tracks data from osgEarth pagedNode2 source for purposes such as determining whether the data necessary to intersect with specified geometry is available, generating commands to page in that geometry, and to determine what to page out when necessary.

virtual bool DtPagedNode2TerrainSourceTracker::dataAvailable	(	DtPagingMetaDataPtr	metaData,
		DtTerrainPagingGeometryPtr	geometry
	)

virtual

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

Reimplemented from DtBoundingVolumeTerrainSourceTracker.

virtual void DtPagedNode2TerrainSourceTracker::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.

Reimplemented from DtBoundingVolumeTerrainSourceTracker.

virtual bool DtPagedNode2TerrainSourceTracker::canPageOutData ( DtTerrainIntersectIDType intersectId )

virtual

Reimplemented from DtBoundingVolumeTerrainSourceTracker.

virtual DtTerrainIntersectIDType DtPagedNode2TerrainSourceTracker::findOldestPagedData ( unsigned int & numTrianglesOut )

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.

Reimplemented from DtBoundingVolumeTerrainSourceTracker.

virtual void DtPagedNode2TerrainSourceTracker::pageOutOldestData ( const int priority )

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.

Reimplemented from DtBoundingVolumeTerrainSourceTracker.

virtual void DtPagedNode2TerrainSourceTracker::addPageInData ( DtNodeBoundingExtendedInfoMap::const_iterator pagedNode2ExtendedInfo )

virtual

Add PagedNode2/Drawable relation information to the pageIn area map.

virtual unsigned int DtPagedNode2TerrainSourceTracker::removePageInData ( DtNodeId node )

virtual

Remove PagedNode2/Drawable relation information from the pageIn area map Return the number of triangles that will be removed.

void DtPagedNode2TerrainSourceTracker::getNodesMappingList ( DrawableList & currentLoadNode )

Return a list of current node loaded (drawable), those one are not in the base tracker class.

void DtPagedNode2TerrainSourceTracker::removeEmptyPagedOutInfo ( DtTerrainPagingGeometryPtr geometry )

remove problematic pageout node
