Detailed Description

Handles a layer specified in the .earth file, and using the feature_custom plugin and point features.

Makes it so that it is rendered using indirect rendering. Contains the indirect registrar that will register the models referred to by the point features in a format that is suitable for consumption by the indirect engine. Maintains a map of each feature tile node it encounters, and a DtIndirectGeometry corresponding to it. Handles loading / unloading of the feature tile nodes This class is not used directly. It is used by the DtIndirectGeometryManager which wil maintain all the layers encountered in the .earth and invoke the methods of the corresponding layer

PPP: This needs to change.

We don't need concurrency here, because the feature data callbacks and the final calls to onDataLoaded/onDataUnLoaded will occur in the main thread

Member Function Documentation

virtual void makVrv::DtIndirectGeometryLayerManager::onDataPremerge ( osg::Node *  newData )

virtual

Called when feature tile pages in.

Called by the DtIndirectGeometryManager before data for this layer has been added to the scenegraph from a background paging thread

virtual void makVrv::DtIndirectGeometryLayerManager::onDataLoaded ( const osg::Node *  newData )

virtual

Called when feature tile pages in.

Called by the DtIndirectGeometryManager when data for this layer is being loaded

virtual void makVrv::DtIndirectGeometryLayerManager::onDataUnloaded ( const osg::Node *  oldData )

virtual

Called when feature tile pages out (is about to be deleted).

Called by the DtIndirectGeometryManager when data for this layer is being unloaded

virtual void makVrv::DtIndirectGeometryLayerManager::processNewFeature ( const osgEarth::Features::CustomFeatureNode *  pFeatureNode, const osg::Node *  data  )

protectedvirtual

Internal method that will actually process the CustomFeatureNodes. Called via onDataLoaded.

virtual bool makVrv::DtIndirectGeometryLayerManager::getModelNode ( const std::string &  modelName, osg::Node *&  modelNode, int &  modelId  )

protectedvirtual

Get the model node after reading the file, and the id for a model name(file) and cache it if does not exist.

Return the cached node and model id, if it exists. Will return false if the model file cannot be read (and modelNode and modelId will be 0).

virtual void makVrv::DtIndirectGeometryLayerManager::registerModelWithRegistrar ( const osg::Node *  modelNode, const std::string &  modelName, const DtModelInfo &  modelInfo  )

protectedvirtual

register a new model with DtIndirectGeometryRegistrar
