// John Allison 31st December 1997.
//
// Class Description:
//
// G4CallbackModel calls a user-defined function containing, for
// example, calls to the Draw methods of G4VVisManager or the
// *Primitive* methods of G4VGraphicsScene. This allows the user to
// add his own graphical objects to a scene. The idea is that the
// callback function is invoked by the vis system to refresh the
// screen or remake a graphical database whenever required. The
// function class must contain:
//
// void operator()(G4VGraphicsScene&, const G4Transform3D&)
//
// A base class G4VUserVisAction is provided in the visualisation
// category. A G4CallbackModel is made by instantiating this template
// with a pointer to the function object. The G4VisManager does this
// for the user if he/she registers it (SetUserAction) and issues the
// command /vis/scene/add/userAction. See the User Guide for
// Application Developers, Section 8.8.7 and 8.8.8.
