class used to collect geometry coming in via feature_geom and add it to the indirect engine. will process point features (expressed as GS or GT) and extruded geometry (procedurally generated) Handles callback from a feature_geom layer in order to add indirect geometry to the scene.

virtual void makVrv::DtIndirectFeatureGeomHandler::onDataPremerge ( osg::Node * data )

virtual

called before data is added to the scenegraph

virtual void makVrv::DtIndirectFeatureGeomHandler::onDataUnloaded ( const osg::Node * data )

virtual

called before data is deleted from the scenegraph

virtual const osg::Node* makVrv::DtIndirectFeatureGeomHandler::preloadModelAndRunDynamicTerrainParser ( const std::string & modelName )

virtual

loads the model and stores a reference pointer to it in the modelName to modelNode map. also waits for other threads to finish if they are loading the same model. Returns a raw point to the model but it is saved in the member variable map so it will not be deleted in the rest of the premerge processing.

virtual void makVrv::DtIndirectFeatureGeomHandler::markTaskFinished ( )

virtual

helper function called by async loader to update atomic counter, and signal the wait condition

virtual void makVrv::DtIndirectFeatureGeomHandler::slot_postTick ( )

virtual

handle the postTick signal.

virtual void makVrv::DtIndirectFeatureGeomHandler::processSubstituteModelFilterNodes ( osg::Node * data )

protectedvirtual

process point replacement features

virtual void makVrv::DtIndirectFeatureGeomHandler::processExtrudeGeometryFilterNodes ( osg::Node * data )

protectedvirtual

process multiple extruded geometry nodes by calling processExtrudeGeometryFilterNode for each one in the data

virtual void makVrv::DtIndirectFeatureGeomHandler::processExtrudeGeometryFilterNode	(	osgEarth::ExtrudeGeometryFilterNode *	pFeatureNode,
		osg::Node *	data
	)

protectedvirtual

process the extruded geometry and add it to the geocell from a DtCellToGeoSpecificIndirectGeoMap

virtual void makVrv::DtIndirectFeatureGeomHandler::processSubstituteModelFilterNode	(	const osgEarth::SubstituteModelFilterNode *	pFeatureNode,
		const osg::Node *	data
	)

protectedvirtual

Internal methods that will actually process the nodes. checks the instancing to see if the layer is GT (instanced) or GS (not instanced) and then calls the appropriate additional processSubstituteModelFilerNodeAs* function.

virtual void makVrv::DtIndirectFeatureGeomHandler::processSubstituteModelFilterNodeAsGT	(	const osgEarth::SubstituteModelFilterNode *	pFeatureNode,
		const osg::Group *	keyNode
	)

protectedvirtual

processes the model filter and adds it to a geocell obtained from the DtCellToGeoTypicalIndirectGeoMap

virtual void makVrv::DtIndirectFeatureGeomHandler::processSubstituteModelFilterNodeAsGS	(	const osgEarth::SubstituteModelFilterNode *	pFeatureNode,
		const osg::Group *	keyNode
	)

protectedvirtual

processes the model filter and adds it to a geocell obtained from the DtCellToGeoSpecificIndirectGeoMap

virtual void makVrv::DtIndirectFeatureGeomHandler::processCustomFeatures ( osg::Node * data )

protectedvirtual

Process the tile to see if there are any custom feature nodes and add them to the indirect system if there are any. These come from feature_custom driver model layers.

virtual void makVrv::DtIndirectFeatureGeomHandler::processCustomFeature	(	const osgEarth::CustomFeatureNode *	pFeatureNode,
		const osg::Node *	key
	)

protectedvirtual

Internal method that will actually process a single CustomFeatureNode. Called via processCustomFeatures.

virtual void makVrv::DtIndirectFeatureGeomHandler::setLayerMask ( const osgEarth::Layer * layer ) const

protectedvirtual

Internal method for setting flags on an incoming layer or layernode.

virtual void makVrv::DtIndirectFeatureGeomHandler::turnOffIntersectionsIfSoSpecified ( const osgEarth::Layer * layer ) const

protectedvirtual

turn off intersections if <intersectable>false</intersectable> was specified for the layer

friend makVrv::DtIndirectFeatureGeomHandler::DtIndirectFeatureGeomHandlerCreator

creator friend class so it is the only one that can create new DtIndirectFeatureGeomHandlers

DtDe& makVrv::DtIndirectFeatureGeomHandler::myDe

protected

osg::observer_ptr<const osgEarth::Layer> makVrv::DtIndirectFeatureGeomHandler::myLayer

protected

store by observer ptr here onDataPremerge for a node can get launched (in another thread) just after the layer has been deleted (e.g. reload) so the layer and hence the nodes being traverse via findTopMostNodeOfType are possibly invalid

DtCellToGeoTypicalIndirectGeoMap* makVrv::DtIndirectFeatureGeomHandler::myCellToGTIndirectGeoMap

protected

GeoTypical stuff.

DtIndirectModelsContainer* makVrv::DtIndirectFeatureGeomHandler::myGTModelsContainer

DtCellToGeoSpecificIndirectGeoMap* makVrv::DtIndirectFeatureGeomHandler::myCellToGSIndirectGeoMap

protected

GeoSpecific stuff.

DtCellToGeoSpecificIndirectGeoMap* makVrv::DtIndirectFeatureGeomHandler::myCellToProceduralGSIndirectGeoMap

protected

Procedural stuff. Is also geospecific in the sense that each tile will have its own registrar. Therefore, we need the gs variant.
