35 // Class description:
36 //
37 // A Box is a cuboid of given half lengths dx,dy,dz. The Box is
38 // centred on the origin with sides parallel to the x/y/z axes.
39 
40 // History:
41 // 30.06.95 P.Kent: Converted from source code developed end 94
42 // 27.03.96 J.Allison: Added virtual functions DescribeYourselfTo() and
43 // SendWireframeTo(G4VGraphicsModel&)
44 // 22.07.96 J.Allison: Changed G4VGraphicsModel to G4VGraphicsScene
45 // and SendPolyhedronTo() to CreatePolyhedron()
46 // 27.03.98 J.Apostolakis: Inherit from G4CSGSolid (not G4VSolid)
47 // 18.11.99 J.Apostolakis, V.Grichine: kUndefined was added to ESide
