1 // Modified for LArG4 by Ben Jones, MIT, Sept 2009
2 //
3 // This class is based upon the default Geant4 optical physics constructor.
4 // However, for optical physics in LArSoft:
5 //
6 // - Cerenkov light can be enabled or disabled as required
7 //
8 // - The default geant4 reflection process is swapped for a simpler
9 // custom boundary process in LArG4
10 //
11 // Parameters relating to the physics in this constructor can be set
12 // in the Utilities/LArParameters service.
