// History:
|
|
// 24.07.95 P.Kent First non-stub version
|
|
// 25.07.96 P.Kent Modified interface for new `Replica' capable geometry
|
|
// 28.08.96 P.Kent Tidied + transform replaced by rotmat+vector
|
|
// 28.02.97 J.Apostolakis Added 2nd constructor with G4Transform3D of solid.
|
|
// 11.07.97 J.Apostolakis Added 3rd constructor with pMotherLogical
|
|
// 11.05.98 J.Apostolakis Added 4th constructor with G4Transform3D & pMotherLV
