Map ORANGE volumes to G4 VolumeId/VolumeInstanceId

Open sethrj opened this issue 8 months ago • 0 comments

Needed for optical physics (#1351 ); we can save the g4 properties during the g4org construction. The VolumeId in ORANGE needs to be changed from an unfolded Universe+Volume ID to arrays mapping {universe ID, local volume ID} -> {VolumeId, PlacedVolumeId}.

RELATED: should we move all the geant4 hierarchy management into the GeantGeoParams? Maybe we just need to have a global and shared "real world" GGP that's constructed at will.
