Helper for managing indirect geometry, its intersection group and registrar corresponding to a 'tile node' (gs cell or gt cell) DtCellToIndirectGeoMap in turn manages a map of feature tile nodes (for a layer) to a corresponding instance of DtCellIndirectGeo.

virtual void makVrv::DtCellIndirectGeo::setModelsContainer	(	DtIndirectModelsContainer *	modelsContainer,
		bool	ownsModelsContainer
	)

virtual

set the models container.

Parameters

ownsModelsContainer whether cell owns the container (and hence should delete on its own destruction. Essentially a value of true transfers ownership to the cell

virtual void makVrv::DtCellIndirectGeo::setParent ( const osg::Group * parent )

virtual

Sets up the parent of the indirect geometry which this manages.

virtual const osg::BoundingBoxd& makVrv::DtCellIndirectGeo::boundingBox ( void ) const

virtual

An indirect geometry doesn't know how to calculate bounding box since this is related to the instances as well as the osg models (that indirect geometry knows nothing about This class computes it for it, and sets itself up as the compute bound call back for the indirect geometry.

virtual const DtIndirectGeometry* makVrv::DtCellIndirectGeo::indirectGeometry ( void ) const

virtual

internal. Access the internally held indirect geometry

virtual DtIndirectGeometry* makVrv::DtCellIndirectGeo::indirectGeometry ( void )

virtual

internal. Access the internally held indirect geometry

virtual osg::Group* makVrv::DtCellIndirectGeo::indirectIntersectionGroup ( )

virtual

get the intersection group for this cell

virtual int makVrv::DtCellIndirectGeo::addInstance ( const DtCellIndirectGeoInstance & cellIndirectGeoInstance )

virtual

internal method to add intersection geometry for an instance of the modelNode, with transform as instanceXForm. returns the instance id in the indirect geometry for the added instance.

virtual const std::unordered_map<int, int>& makVrv::DtCellIndirectGeo::modelIdToNumInstances ( void ) const

virtual

get the map of model ids to num of instances

virtual void makVrv::DtCellIndirectGeo::expandBoundingBox	(	const osg::Node *	modelNode,
		const osg::Matrixd &	instanceXForm
	)

protectedvirtual

internal method to actually expand the bounding box based on the instance xform as well as the model node (and hence the model bbox in question)
