32 // Class Description:
33 //
34 // G4VModel is a base class for visualization models. A model is a
35 // graphics-system-indepedent description of a Geant4 component.
36 // The key fuctionality of a model is to know how to describe itself
37 // to a scene handler. A scene is a collection of models.
38 // A special case is made for G4PhysicalVolumeModel - a non-null pointer
39 // is to be returned by G4PhysicalVolumeModel::GetG4PhysicalVolumeModel().
