It allows to combine several volumes together in an arbitrary way // in 3D space and then work with the result as with a single logical volume // for placement. // The resulting objects are independent copies of each of the assembled // logical volumes. The placements are not, however, bound one to each other // when placement is done. They are seen as independent physical volumes in // space. // Author: Radovan Chytracek, John Apostolakis, Gabriele Cosmo // Date: November 2000 // // History: // March 2006, I.Hrivnacova - Extended to support assembly of assemblies // of volumes and reflections // ---------------------------------------------------------------------- #ifndef G4_ASSEMBLYVOLUME_H #define G4_ASSEMBLYVOLUME_H #include #include "G4Transform3D.hh" #include "G4AssemblyTriplet.hh" class G4VPhysicalVolume; class G4AssemblyVolume { public: // with description G4AssemblyVolume(); G4AssemblyVolume( G4LogicalVolume* volume, G4ThreeVector& translation, G4RotationMatrix* rotation); ~G4AssemblyVolume(); // // Constructors & destructor. // At destruction all the generated physical volumes and associated // rotation matrices of the imprints will be destroyed. // // The rotation matrix passed as argument can be 0 (identity) or an address // even of an object on the upper stack frame.
