37 //
38 // A G4Trd is a trapezoid with the x and y dimensions varying along z
39 // functions:
40 //
41 // Member Data:
42 //
43 // fDx1 Half-length along x at the surface positioned at -dz
44 // fDx2 Half-length along x at the surface positioned at +dz
45 // fDy1 Half-length along y at the surface positioned at -dz
46 // fDy2 Half-length along y at the surface positioned at +dz
47 // fDz Half-length along z axis
48 
49 // History:
50 // 12.01.95 P.Kent: Old prototype code converted to thick geometry
51 // 17.02.95 P.Kent: Exiting normal return
52 // 19.08.96 P.Kent, V.Grichine: Fs in accordance with G4Box
53 // 21.04.97 J.Apostolakis: Added Set Methods
54 // 19.11.99 V.Grichine: kUndefined was added to Eside enum
