Visualization category of GEANT4

• GEANT4 visualization is controlled by class G4VisManager
• GEANT4 has an abstract interface to arbitrary graphics systems
• An arbitrary graphics system can easily be plugged in by writing explicit implimentation of 3 classes:

  1.

  class G4MyGS : public G4VGraphicsSystem

  • Initializer

  2.

  class G4MyGSScene : public G4VScene

  • Modeling

  3.

  class G4MyGSView : public G4VView

  • Rendering

• G4MyGS, G4MyGSScene, and G4MyGSView are called ``MyGS driver'', which means ``interface to MyGS''
