You may choose a graphics system (driver) with a parameter of
the command "/vis/open" or "/vis/sceneHandler/create",
or you may omit the driver parameter and choose at run time:
- by argument in the construction of G4VisExecutive
- by environment variable "G4VIS_DEFAULT_DRIVER"
- by entry in "~/.g4session"
- by build flags.
- Note: This feature is not allowed in batch mode.
For further information see "examples/basic/B1/exampleB1.cc"
and "vis.mac".
