32 // Class Description:
33 //
34 // G4CallbackModel calls a user-defined function containing, for
35 // example, calls to the Draw methods of G4VVisManager or the
36 // *Primitive* methods of G4VGraphicsScene. This allows the user to
37 // add his own graphical objects to a scene. The idea is that the
38 // callback function is invoked by the vis system to refresh the
39 // screen or remake a graphical database whenever required. The
40 // function class must contain:
41 //
42 // void operator()(G4VGraphicsScene&, const G4Transform3D&)
43 //
44 // A base class G4VUserVisAction is provided in the visualisation
45 // category. A G4CallbackModel is made by instantiating this template
46 // with a pointer to the function object. The G4VisManager does this
47 // for the user if he/she registers it (SetUserAction) and issues the
48 // command /vis/scene/add/userAction. See the User Guide for
49 // Application Developers, Section 8.8.7 and 8.8.8.
