Set whether the database pager should pre compile OpenGL objects before allowing them to be merged into the scene graph.

Pre compilation helps reduce the chances of frame drops, but also slows the speed at which tiles are merged as they have to be compiled first.

Set how loaded drawables should be handled w.r.t their display list/vertex buffer object/vertex array settings.

void osgDB::DatabasePager::setIncrementalCompileOperation ( osgUtil::IncrementalCompileOperation * ico )

inline

void osgDB::DatabasePager::setMaxAnisotropyPolicy	(	bool	changeAnisotropy,
		float	valueAnisotropy

Set the priority of the database pager thread(s).

void osgDB::DatabasePager::setTargetMaximumNumberOfPageLOD ( unsigned int target )

inline

Set the target maximum number of PagedLOD to maintain in memory.

Note, if more than the target number are required for rendering of a frame then these active PagedLOD are excempt from being expiried. But once the number of active drops back below the target the inactive PagedLOD will be trimmed back to the target number.

void osgDB::DatabasePager::setUnrefImageDataAfterApplyPolicy	(	bool	changeAutoUnRef,
		bool	valueAutoUnRef
	)

inline

Set whether newly loaded textures should have their UnrefImageDataAfterApply set to a specified value.

		unsigned int	numHttpThreads = `1`
	)

virtual void osgDB::DatabasePager::signalBeginFrame ( const osg::FrameStamp * framestamp )

virtual

Signal the database thread that the update, cull and draw has begun for a new frame.

Note, this is called by the application so that the database pager can go to sleep while the CPU is busy on the main rendering threads.

virtual void osgDB::DatabasePager::signalEndFrame ( )

virtual

Signal the database thread that the update, cull and draw dispatch has completed.

Note, this is called by the application so that the database pager can go to wake back up now the main rendering threads are iddle waiting for the next frame.

virtual void osgDB::DatabasePager::updateSceneGraph ( const osg::FrameStamp & frameStamp )

virtual

Merge the changes to the scene graph by calling calling removeExpiredSubgraphs then addLoadedDataToSceneGraph.

Note, must only be called from single thread update phase.
