Detailed Description

Load problem data directly from Geant4.

This can be used to circumvent ROOT as a serialization tool, whether to simplify the toolchain or to integrate better with user frameworks. As much data as possible is imported (subject to the data selection); downstream Celeritas classes will validate the imported data as needed.

GeantImporter import(GeantSetup("blah.gdml"));
ImportData data = import();

or to import from an existing, initialized Geant4 state:

GeantImport import(world_volume);
ImportData data = import();

Member Function Documentation

get_world_volume()

G4VPhysicalVolume const * celeritas::GeantImporter::get_world_volume ( )

inlinestatic

Get an externally loaded Geant4 top-level geometry element.

This is only defined if Geant4 has already been set up. It's meant to be used in concert with GeantImporter or other Geant-importing classes.
