virtual

Parameters

instanceXForm	is the 'absolute' 64 bit transformation
modelId	per the registrar
modelNode	the top level osg node corresponding to the model geometry

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.
