handles the management of paged tiles and terrain patches being added to the indirect rendering system. For every terrain patch and paged tile it parses them to find any proxys or geodes and sends them off to the indirect system.

	)

virtual

Indirect a node directly (utility function) can be used to indirect a scenegraph, so whole openflight terrains can be passed in here should only be called in the main thread NOTE: each time the signature of this function change the same change needs to be made in JrmDisabledIndirectManager.h.

Reimplemented in DtDisabledIndirectManager.

virtual void makVrv::DtPagedTilesIndirectManager::nodePagingOut ( const osg::Node * node )

virtual

Let the manger know a node is paging out should only be called in the main thread' NOTE: each time the signature of this function change the same change needs to be made in JrmDisabledIndirectManager.h.

Reimplemented in DtDisabledIndirectManager.

virtual void makVrv::DtPagedTilesIndirectManager::addTextureLoaderToSceneGraph ( osg::Group & myTerrainGroup )

virtual

Add a texture loader node to the scenegraph. It processes textures and gets them to loaded (onto the GPU) should only be called by the main thread NOTE: each time the signature of this function change the same change needs to be made in JrmDisabledIndirectManager.h.

Reimplemented in DtDisabledIndirectManager.

virtual void makVrv::DtPagedTilesIndirectManager::slot_postTick ( )

virtual

handle the postTick signal. This -checks whether instances in each cell for the terrain skin are ready to render and emits signal_terrainInstancesReadyToRender, if so

virtual

node for tracking which metaflight terrain patch this manager is managing.

protectedvirtual

slot for when a paged tile is loaded (but not added to the scenegraph) called by the paged in a background thread. it updates the signal count since it can be called in the background NOTE: each time the signature of this function change the same change needs to be made in JrmDisabledIndirectManager.h

Reimplemented in DtDisabledIndirectManager.

		const osg::Node *	child
	)

protectedvirtual

slot for when paged tile has already been paged in only called in the main thread.
