19Merging the VirtualMC branch to the main development branch (HEAD)
20
b9d0a01d 21Revision 1.18.10.2 2002/08/30 15:45:54 alibrary
22Adding geant4vmc support
23
24Revision 1.18.10.1 2002/06/10 17:51:15 hristov
25Merged with v3-08-02
26
27Revision 1.18 2001/05/30 16:15:47 fca
28Correct comparison wiht AliGeant3::Class() introduced. Thanks to I.Hrivnacova
29
cbfdea0d 30Revision 1.17 2001/05/30 15:55:35 hristov
31Strings compared instead of pointers
32
268b9c60 33Revision 1.16 2001/05/30 14:04:31 hristov
34Dynamic cast replaced (F.Carminati)
35
4154d3d8 36Revision 1.15 2001/05/25 06:47:16 hristov
37Bug 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)
38
3e225ff6 39Revision 1.14 2001/05/16 14:57:16 alibrary
40New files for folders and Stack
41
9e1a0ddb 42Revision 1.13 2001/05/09 01:00:19 nilsen
43Fixed up a typo in the cout of Init(). Now properly indecates which version
44of code is being used.
45
82140a73 46Revision 1.12 2001/04/18 12:06:02 barbera
47Number of modules in layer 5 and 6 re-set to 23 and 26
48
18c21458 49Revision 1.11 2001/03/23 00:12:23 nilsen
50Set Reading of AliITSgeom data from Geant3 common blocks as the default and
51not a .det file. Removed redundent calls to BuildGeometry.
52
0646a0e8 53Revision 1.10 2001/02/14 14:22:58 nilsen
54Now looking in the right director for the old .det.
55
202679a1 56Revision 1.9 2001/02/14 14:12:43 nilsen
57Forgot about the nonexisting v in ITSgeometry_5.det.
58
262d891d 59Revision 1.8 2001/02/14 14:06:23 nilsen
60Wrong default .det file name for old .det file format.
61
88cc8e8a 62Revision 1.7 2001/02/13 16:53:35 nilsen
63Fixed a but when trying to use GEANT4. Needed to replace
64if(!((TGeant3*)gMC)) with if(!(dynamic_casst<TGeant3*>(gMC)))
65because just casting gMC to be TGeant3* even when it realy is a TGeant3 pointer
66did not result in a zero value. For AliITSv5asymm and AliITSv5symm, needed
67to fix a bug in the initilizers and a bug in BuildGeometry. This is now done
68in the same way as in AliITSv5.cxx.
69
9a4c6ea3 70Revision 1.6 2001/02/09 20:06:26 nilsen
71Fixed bug in distructor. Can't distroy fixxed length arrays. Thanks Peter.
