Member Function Documentation

virtual DtTerrainSourceTracker* DtMetaflightTerrainSourcePager::createTerrainSourceTracker

(

)

[virtual]

Creates and returns a DtOsgTerrainSourceTracker.

Implements DtTerrainSourcePager.

virtual bool DtMetaflightTerrainSourcePager::pageInGeometry	(	const DtTerrainPagingGeometryPtr	geometry,
		const unsigned int	intersectId = 0
	)		[virtual]

This function must page in all the geometry specified by the argument, and return true when successful.

If this method returns false, it will be called again later, until it returns true or times out.

Implements DtBoundingVolumeTerrainSourcePager.

virtual bool DtMetaflightTerrainSourcePager::pageOutNodes

(

std::list< DtNodeId > &

nodesToRemove

)

[virtual]

This function must cause the page out of the nodeIds specified.

It should return true when successful. It will be called repeatedly with the same arguments until it succeeds.

Implements DtBoundingVolumeTerrainSourcePager.

virtual void DtMetaflightTerrainSourcePager::updateTerrain

(

const unsigned int

intersectId = 0

)

[virtual]

Implements DtBoundingVolumeTerrainSourcePager.

virtual void DtMetaflightTerrainSourcePager::updatePageTracker

(

const unsigned int

intersectId = 0

)

[virtual]

Implements DtBoundingVolumeTerrainSourcePager.

static DtTerrainSourcePager* DtMetaflightTerrainSourcePager::terrainChooserFunction	(	osg::Node &	node,
		DtVantageTerrainEngine *	terrainEngine
	)		[static]

This is the function that is registered with the DtTerrainSourceChooser.

If node is a DtHierarchicalPagedLod node, then a DtMetaflightTerrainSourcePager is returned.

static DtNodeId DtMetaflightTerrainSourcePager::osgNodeId

(

makVrv::DtHierarchicalPagedLod *

node

)

[static, protected]

Methods for converting to/from DtNodeId.

These are protected, because only the pager should be accessing NodeIds as if they are actual nodes. The tracker does not do that since it operates in a separate thread.

static makVrv::DtHierarchicalPagedLod* DtMetaflightTerrainSourcePager::nodeFromId

(

DtNodeId

nodeId

)

[static, protected]

Methods for converting to/from DtNodeId.

These are protected, because only the pager should be accessing NodeIds as if they are actual nodes. The tracker does not do that since it operates in a separate thread.
