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