Member Function Documentation

virtual bool DtBoundingVolumeTerrainSourcePager::pageInGeometry	(	const DtTerrainPagingGeometryPtr	geometry,
		const unsigned int	intersectId = 0
	)		[pure 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.

Implemented in DtMetaflightTerrainSourcePager, and DtPagedLodTerrainSourcePager.

virtual bool DtBoundingVolumeTerrainSourcePager::pageOutNodes

(

std::list< DtNodeId > &

nodesToRemove

)

[pure 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.

Implemented in DtMetaflightTerrainSourcePager, and DtPagedLodTerrainSourcePager.

virtual void DtBoundingVolumeTerrainSourcePager::updateTerrain

(

const unsigned int

intersectId = 0

)

[pure virtual]

Implemented in DtMetaflightTerrainSourcePager, and DtPagedLodTerrainSourcePager.

virtual void DtBoundingVolumeTerrainSourcePager::updatePageTracker

(

const unsigned int

intersectId = 0

)

[pure virtual]

Implements DtTerrainSourcePager.

Implemented in DtMetaflightTerrainSourcePager, and DtPagedLodTerrainSourcePager.
