0002 G4CXSimulateTest.cc
0003 ====================
0004
0005 GGeo creation done when starting from gdml or live G4, still needs Opticks instance,
0006 TODO: avoid this by replacing with automated SOpticks instanciated by OPTICKS_LOG
0007 and reimplemnting geometry translation in a new more direct "Geo" package
0008
0009 Formerly did "U4Material::LoadBnd()" here in main
0010 which created G4 materials from the persisted bnd.npy
0011 that requires CFBASE or OPTICKS_KEY to derive it
0012 in order to load SSim from $CFBase/CSGFoundry/SSim)
0013
0014 Clearly that is not acceptable when running from live Geant4 or GDML,
0015 so cannot U4Material::LoadBnd from main.
0016
0017 The new workflow equivalent would be to access the SSim instance
0018 and get the bnd.npy arrays that way.
