	)

protectedvirtual

Reloads a tile and keeps track of cratering events that affect the tile.

tileKey	the TileKey of the tile to reload
isRemoval	true if the crater is being removed, false if its being added
numEvents	the number of craters for the reload

Returns: true if the tile was reloaded

virtual bool DtOsgEarthTerrainSourcePager::findFirstParent	(	osgEarth::TileKey &	firstParentTileKey,

protectedvirtual

Finds the TileKey of the first parent key for tiledata that is loaded.

Parameters

firstParentTileKey	the first parent key that was found
tileKey	the key looking for the first parent

Returns: true if a parent key is found of the key, false otherwise

virtual bool DtOsgEarthTerrainSourcePager::modifyMaskExtentsForFirstParent	(	const boost::shared_ptr< DtTileData >	tileData,
		bool	isRemoval = `false`
	)

protectedvirtual

Modifies the mask extents of the first parent tile so that intersection calls will use the hi-res tile data instead.

Parameters

tileData	the hi-res tile data to add to the mask extents for the parent tile
isRemoval	is set to true if the crater is being removed else set to false if its being added return true if a parent was found, false otherwise

virtual bool DtOsgEarthTerrainSourcePager::pageInTile	(	const osgEarth::TileKey &	tileKey,
		DtTerrainIntersectIDType	intersectId = `0`
	)

protectedvirtual

Creates the requested osg heightfield, adds the heightfield as a collision shape to the bullet collision world, and adds the record of the tile to the pager's terrainSourceTracker for tracking and paging out purposes.

Parameters

tileIds	The tileKey to create heightfield for.
intersectId	Optional parameter to create the tiles with a starting "lastUsed" value of intersectId.

Returns: True if the heightfield is created, the collision object is created and added to the collision world, and the tracking info is added to the terrainSourceTracker.

virtual bool DtOsgEarthTerrainSourcePager::pageOutTile ( const osgEarth::TileKey & tileKey )

protectedvirtual

Removes the heightfield and the corresponding collision object from the collision world.

Also removes the tracker's reference to this tile, decrements the terrainEngine's number of triangles, and number of pending page out commands.

Returns: True if all data is successfully removed.

virtual boost::shared_ptr<DtTileData> DtOsgEarthTerrainSourcePager::createTileDataFromTileModel	(	const osgEarth::TileKey &	tilekey,
		DtTerrainIntersectIDType	intersectId,
		bool	createIfAlreadyLoaded = `false`
	)		const

protectedvirtual

Sets up and returns a new DtTileData object from an osgearth tile model.

Parameters

tilekey	Tile to create.
intersectId	IntersectId to seed the tileData with for page-out priority.
createIfAlreadyLoaded	setting to true forces it create tile data regardless if it is already loaded.

Returns: Newly created DtTileData.

virtual boost::shared_ptr<DtTileData> DtOsgEarthTerrainSourcePager::createTileDataFromHeightfield	(	const osgEarth::TileKey &	tilekey,
		DtTerrainIntersectIDType	intersectId,
		const osg::ref_ptr< const osg::HeightField > &	heightfield
	)		const

protectedvirtual

Sets up and returns a new DtTileData object from a heightfield.

Parameters

tilekey	Tile to create.
intersectId	IntersectId to seed the tileData with for page-out priority.
heightfield	Elevation data for tile.

virtual boost::shared_ptr<DtTileData> DtOsgEarthTerrainSourcePager::createTileDataFromGeometry	(	const osgEarth::TileKey &	tilekey,
		DtTerrainIntersectIDType	intersectId,
		const osg::ref_ptr< osg::Node > &	geometry
	)		const

protectedvirtual

Sets up and returns a new DtTileData object from geometry.

Parameters

tilekey	Tile to create.
intersectId	IntersectId to seed the tileData with for page-out priority.
geometry	Geometry data for tile.

virtual void DtOsgEarthTerrainSourcePager::addTile	(	const osgEarth::TileKey &	tilekey,
		const boost::shared_ptr< DtTileData > &	tile
	)

protectedvirtual

Adds a configured tile data object to the terrain.

Parameters

tilekey Key for the area which is being enabled on the tile. This is not necessarily the same as the key for the tile model in the tile data. If it is not then it is a descendant of that key.

tile Tile data to add. The same tile data may be added multiple times, each time with different tilekey parameter because different subareas of the tile data are being paged in. This is because if we page in tile data due to intersections in one area, there may be higher resolution data in other areas so we have to keep track of which areas have been checked. This is all done in createTileDataFromTileModel.

virtual void DtOsgEarthTerrainSourcePager::addEmptyTile	(	const osgEarth::TileKey &	tilekey,
		DtTerrainIntersectIDType	intersectId = `0`
	)

protectedvirtual

Used when a tile cannot be created by osgEarth's tileBuilder.

Creates a Terrain Tile with all heights at 0.

virtual void DtOsgEarthTerrainSourcePager::addMasks	(	const osgEarth::TileKey &	tilekey,
		const boost::shared_ptr< DtTileData > &	tile
	)

protectedvirtual

Called from addTile to process and add mask geometry to collision world.
