4ae5bbc4 21Revision 1.14 2002/10/14 14:57:08 hristov
22Merging the VirtualMC branch to the main development branch (HEAD)
23
b9d0a01d 24Revision 1.13.10.2 2002/08/30 15:45:54 alibrary
25Adding geant4vmc support
26
27Revision 1.13.10.1 2002/06/10 17:51:15 hristov
28Merged with v3-08-02
29
30Revision 1.13 2001/05/30 16:15:47 fca
31Correct comparison wiht AliGeant3::Class() introduced. Thanks to I.Hrivnacova
32
cbfdea0d 33Revision 1.12 2001/05/30 15:55:35 hristov
34Strings compared instead of pointers
35
268b9c60 36Revision 1.11 2001/05/30 14:04:31 hristov
37Dynamic cast replaced (F.Carminati)
38
4154d3d8 39Revision 1.10 2001/05/25 06:47:16 hristov
40Bug 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)
41
3e225ff6 42Revision 1.9 2001/04/18 12:07:37 barbera
43Number of modules in layer 5 and 6 re-set to 23 and 26
44
18c21458 45Revision 1.8 2001/03/23 00:12:23 nilsen
46Set Reading of AliITSgeom data from Geant3 common blocks as the default and
47not a .det file. Removed redundent calls to BuildGeometry.
48
0646a0e8 49Revision 1.7 2001/02/13 16:53:35 nilsen
50Fixed a but when trying to use GEANT4. Needed to replace
51if(!((TGeant3*)gMC)) with if(!(dynamic_casst<TGeant3*>(gMC)))
52because just casting gMC to be TGeant3* even when it realy is a TGeant3 pointer
53did not result in a zero value. For AliITSv5asymm and AliITSv5symm, needed
54to fix a bug in the initilizers and a bug in BuildGeometry. This is now done
55in the same way as in AliITSv5.cxx.
56
9a4c6ea3 57Revision 1.6 2001/02/09 20:06:26 nilsen
58Fixed bug in distructor. Can't distroy fixxed length arrays. Thanks Peter.
