Detailed Description

DtOsgEarthStreamedFeatureManager is an osgEarth-specific implemenation of a DtStreamedFeatureManager.

The manager uses a DtOsgEarthFeatureDataBroker to detect when tiles page in, and looks for CustomFeatureNodes in the sceneGraph of that tile. When found, those feature requests are processed using any registered creators

Member Function Documentation

virtual void makVrv::DtOsgEarthStreamedFeatureManager::processNewFeatures ( const osgEarth::CustomFeatureNode *  featureNode )

protectedvirtual

When a callback on the DtOsgEarthFeatureDataBroker is fired, it looks for CustomFeatureNodes attached to nodes in the tile's scenegrph.

These get passed onto processNewFeatures() which calls any registered creators for the features contained within

virtual void makVrv::DtOsgEarthStreamedFeatureManager::slot_customFeatureNodeToBeDeleted ( const osgEarth::CustomFeatureNode *  node )

protectedvirtual

The DtOsgEarthFeatureDataBroker callback connects the DtCustomFeatureNode's signal_aboutToBeDeleted to the our slot_customFeatureNodeToBeDeleted slot.

virtual void makVrv::DtOsgEarthStreamedFeatureManager::onDataLoaded ( const osgEarth::Map *  map, const osgEarth::Layer *  layer, const osg::Node *  data  )

protectedvirtual

virtual void makVrv::DtOsgEarthStreamedFeatureManager::checkAndProcessStrandedFeatures ( )

protectedvirtual

Method called by the sceneDriver tick to process any features that need to be deleted.

This method is mutex-protected, since features are placed on the stranded list from osgEarth paging threads (and the list will be processed in the render thread).

Implements makVrv::DtStreamedFeatureManager.

virtual void makVrv::DtOsgEarthStreamedFeatureManager::slot_terrainPatchCreated ( DtTerrainPatchObject &  patch )

protectedvirtual

Find out when the terrain patch is ready to accept DtOsgEarthFeatureDataBroker callbacks.

When this signal fires, the manager looks up a terrain patch and installs an osgEarth data broker callback on osgEarth patches

virtual void makVrv::DtOsgEarthStreamedFeatureManager::moveFeaturesToStrandedList ( const osgEarth::CustomFeatureNode *  featureNode )
