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.

Member Function Documentation

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

overridevirtual

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

Reimplemented from DtBoundingVolumeTerrainSourceTracker.

virtual DtTerrainCategoryMask DtPagedNode2TerrainSourceTracker::terrainCategories ( ) const

overridevirtual

Returns: A bitfield indicating the terrain categories that this tracker is used for. Default implementation returns DtTerrainCategoryAll. Subclasses are expected to override and replace with more specific terrain categories where applicable.

Reimplemented from DtTerrainSourceTracker.

virtual void DtPagedNode2TerrainSourceTracker::pageInData	(	DtPagingMetaDataPtr	metaData,
		DtTerrainPagingGeometryPtr	geometry
	)

overridevirtual

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 )

overridevirtual

Reimplemented from DtBoundingVolumeTerrainSourceTracker.

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

overridevirtual

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 )

overridevirtual

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.

virtual void DtPagedNode2TerrainSourceTracker::getNodesMappingList ( DrawableList & currentLoadNode )

virtual

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
