Detailed Description

Builder creating a pseudo G4 geometry starting from a TGeo geometry.

To invoke the method Construct() the ROOT geometry must be in memory. The G4 objects created are:

• TGeoElement ---> G4Element
• TGeoMaterial/TGeoMixture ---> G4Material
• TGeoMatrix ---> G4RotationMatrix
• TGeoVolume ---> G4LogicalVolume
• TGeoShape ---> TG4RootSolid : public G4Solid
• TGeoNode ---> G4PVPlacement : public G4VPhysicalVolume
