Visualization
By default, Geant4 VMC supports only this Geant4 VIS/UI setting:
OPENGLX OPENGLXM XM TCSH
In order to get supported all Geant4 visualization/UI drivers user can customise the geant4_vmc/source/Makefile as described in the comments in this file. All Geant4 graphics drivers and UIs can be then used within Geant4 VMC, however not all these options were tested in this environment and even though a correct behaviour is expected, it is not guaranteed.
The G3-like functions for visualization defined in TVirtualMC are overcome with the interactive visualization capabilities of both Root and Geant4 geometry modellers, that's why user is encouraged to use these modeller directly. User can set Geant4 visualization options using Geant4 visualization commands, as it is illustrated in the VMC examples in g4vis.in macro.
