36 // G4TheMTRayTracer
37 // This is a graphics driver of Geant4 which generates a figure file by
38 // ray tracing technique. The format of output figure file can be selected
39 // by assigning a pointer of G4VFigureFileMaker concrete class object.
40 // The main entry of ray tracing is Trace() method, which is available
41 // only at Idle state. G4TheMTRayTracer shoots rays and controls its own event
42 // loop. It generates G4Event objects used for its own purpose. When ray
43 // tracing is working, all sensitive detectors are inactivated and all
44 // user action classes are swapped out. Still, verbosities set to Geant4
45 // manager classes are concerned. Thus, it is recommended to set verbosities
46 // to minimum (usually zero).
47 // G4TheMTRayTracer can visualise absolutely all kinds of geometrical shapes
48 // which G4Navigator can deal with. Instead, it can NOT visualise hits
49 // nor trajectories generated by usual simulation.
