18 Revision 1.19 2002/10/14 14:57:08 hristov
19 Merging the VirtualMC branch to the main development branch (HEAD)
21 Revision 1.18.10.2 2002/08/30 15:45:54 alibrary
22 Adding geant4vmc support
24 Revision 1.18.10.1 2002/06/10 17:51:15 hristov
27 Revision 1.18 2001/05/30 16:15:47 fca
28 Correct comparison wiht AliGeant3::Class() introduced. Thanks to I.Hrivnacova
30 Revision 1.17 2001/05/30 15:55:35 hristov
31 Strings compared instead of pointers
33 Revision 1.16 2001/05/30 14:04:31 hristov
34 Dynamic cast replaced (F.Carminati)
36 Revision 1.15 2001/05/25 06:47:16 hristov
37 Bug fix in the creation of the AliITSgeom::fShape entry for SPD. Now there is both a proper shape entry and a default, should there be future changes. This bug was related to fMinorVersion=3 was not antisipated. (B.Nilsen)
39 Revision 1.14 2001/05/16 14:57:16 alibrary
40 New files for folders and Stack
42 Revision 1.13 2001/05/09 01:00:19 nilsen
43 Fixed up a typo in the cout of Init(). Now properly indecates which version
44 of code is being used.
46 Revision 1.12 2001/04/18 12:06:02 barbera
47 Number of modules in layer 5 and 6 re-set to 23 and 26
49 Revision 1.11 2001/03/23 00:12:23 nilsen
50 Set Reading of AliITSgeom data from Geant3 common blocks as the default and
51 not a .det file. Removed redundent calls to BuildGeometry.
53 Revision 1.10 2001/02/14 14:22:58 nilsen
54 Now looking in the right director for the old .det.
56 Revision 1.9 2001/02/14 14:12:43 nilsen
57 Forgot about the nonexisting v in ITSgeometry_5.det.
59 Revision 1.8 2001/02/14 14:06:23 nilsen
60 Wrong default .det file name for old .det file format.
62 Revision 1.7 2001/02/13 16:53:35 nilsen
63 Fixed a but when trying to use GEANT4. Needed to replace
64 if(!((TGeant3*)gMC)) with if(!(dynamic_casst<TGeant3*>(gMC)))
65 because just casting gMC to be TGeant3* even when it realy is a TGeant3 pointer
66 did not result in a zero value. For AliITSv5asymm and AliITSv5symm, needed
67 to fix a bug in the initilizers and a bug in BuildGeometry. This is now done
68 in the same way as in AliITSv5.cxx.
70 Revision 1.6 2001/02/09 20:06:26 nilsen
71 Fixed bug in distructor. Can't distroy fixxed length arrays. Thanks Peter.
73 Revision 1.5 2001/02/09 00:05:31 nilsen
74 Added fMajor/MinorVersion variables and made other changes to better make
75 use of the new code changes in AliITSgeom related classes.
77 Revision 1.4 2001/02/02 23:57:29 nilsen
78 Added include file that are no londer included in AliITSgeom.h
80 Revision 1.3 2001/01/30 09:23:13 hristov
81 Streamers removed (R.Brun)
83 Revision 1.2 2000/11/30 11:13:11 barbera
84 Added changes suggested by Federico Carminati on nov, 30, 2000
86 Revision 1.1 2000/10/07 15:46:38 barbera
87 Version 5 of the geometry with asymmetric services
89 Revision 1.25 2000/10/05 20:50:00 nilsen
90 Now using root generated streamers.
92 Revision 1.14.4.12 2000/10/02 16:04:03 barbera
93 Forward declarations added
95 Revision 1.22 2000/07/10 16:07:19 fca
96 Release version of ITS code
98 Revision 1.14.4.4 2000/05/19 10:10:21 nilsen
99 fix for bug with HP and Sun unix + fix for event display in ITS-working branch
101 Revision 1.14.4.3 2000/03/04 23:46:38 nilsen
102 Fixed up the comments/documentation.
104 Revision 1.14.4.2 2000/03/02 21:53:02 nilsen
105 To make it compatable with the changes in AliRun/AliModule.
107 Revision 1.14.4.1 2000/01/12 19:03:33 nilsen
