makVrv::DtIndirectBuildingsHandler Class Reference

class used to collect geometry coming in via buildings layer and add it to the indirect engine. will process: -external references (gs) -instanced references (gt) -procedural geometry (gt) -procedural geometry (gt) -instanced roofs (gt) Handles callbacks from a buildings layer premerge callback to add the data to the indirect engine

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

virtual

Callback for osgEarth premerge callback which is called in the background paging thread when the tile has been loaded but not yet added to the scenegraph.

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

virtual

Callback for osgEarth unloaded callback which is called in the main render thread when a tile is being paged out.

virtual void makVrv::DtIndirectBuildingsHandler::slot_postTick ( )

virtual

handle the postTick signal.

virtual void makVrv::DtIndirectBuildingsHandler::processBuildingsExternalModelNodes ( const osg::Node *  data )

protectedvirtual

handle external references in the buildings layer (gs)

virtual void makVrv::DtIndirectBuildingsHandler::processInstancedModelNodes ( const osg::Node *  data )

protectedvirtual

handle instanced models in the buildings layer (gt)

virtual void makVrv::DtIndirectBuildingsHandler::processElevationsLodNodes ( const osg::Node *  data )

protectedvirtual

handle tagged geodes in the buildings layer (these are the geodes corresponding to procedural geo corresponding to the elevations in the buildings layer)

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

protected

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.

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

DtDe& makVrv::DtIndirectBuildingsHandler::myDe

protected

osg::observer_ptr<const osgEarth::Layer> makVrv::DtIndirectBuildingsHandler::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

DtCellToGeoSpecificIndirectGeoMap* makVrv::DtIndirectBuildingsHandler::myGsMap

protected

external models go here geospecific

DtCellToGeoTypicalIndirectGeoMap* makVrv::DtIndirectBuildingsHandler::myGtMap

protected

instanced models go here geotypical, share models

DtIndirectModelsContainer* makVrv::DtIndirectBuildingsHandler::myGtModelsContainer

protected

DtCellToGeoSpecificIndirectGeoMap* makVrv::DtIndirectBuildingsHandler::myProceduralGsMap

protected

Procedural stuff that ends up as geodes. Is also geospecific in the sense that each.
