This is the first release of G4VG, which uses in-memory Geant4 geometry to build VecGeom. The code is entirely derivative from Celeritas, written primarily by @sethrj and @mrguilima , and adapted to an independent repository with the help of @drbenmorgan and supervision of @agheata et al. The original code was inspired by similar conversion work done by @sawenzel and @jonapost in G4VecGeomNav. Conversion of the following Geant4 solids is supported: G4Box G4Cons G4CutTubs G4Ellipsoid G4EllipticalCone G4EllipticalTube G4ExtrudedSolid G4GenericPolycone G4GenericTrap G4Hype G4IntersectionSolid G4Orb G4Para G4Paraboloid G4Polycone G4Polyhedra G4ReflectedSolid G4Sphere G4SubtractionSolid G4TessellatedSolid G4Tet G4Torus G4Trap G4Trd G4Tubs G4UnionSolid And physical volumes: G4PVPlacement G4VPVParameterisation Version 1.0.1 This fixes a small issue where world physical volume mapping was not returned from the converter. Version 1.0.2 This introduces new options to improve compatibility with AdePT and fixes for different build configurations.
