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

set the cull shader config

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.
