25 | Adding geant4vmc support | |
26 | ||
27 | Revision 1.13.10.1 2002/06/10 17:51:15 hristov | |
28 | Merged with v3-08-02 | |
29 | ||
30 | Revision 1.13 2001/05/30 16:15:47 fca | |
31 | Correct comparison wiht AliGeant3::Class() introduced. Thanks to I.Hrivnacova | |
32 | ||
cbfdea0d | 33 | Revision 1.12 2001/05/30 15:55:35 hristov |
34 | Strings compared instead of pointers | |

37 | Dynamic cast replaced (F.Carminati) | |
38 | ||

40 | 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) | |
41 | ||
3e225ff6 | 42 | Revision 1.9 2001/04/18 12:07:37 barbera |
43 | Number of modules in layer 5 and 6 re-set to 23 and 26 | |
44 | ||
18c21458 | 45 | Revision 1.8 2001/03/23 00:12:23 nilsen |
46 | Set Reading of AliITSgeom data from Geant3 common blocks as the default and | |
47 | not a .det file. Removed redundent calls to BuildGeometry. | |
48 | ||
0646a0e8 | 49 | Revision 1.7 2001/02/13 16:53:35 nilsen |
50 | Fixed a but when trying to use GEANT4. Needed to replace | |
51 | if(!((TGeant3*)gMC)) with if(!(dynamic_casst<TGeant3*>(gMC))) | |
52 | because just casting gMC to be TGeant3* even when it realy is a TGeant3 pointer | |
53 | did not result in a zero value. For AliITSv5asymm and AliITSv5symm, needed | |
54 | to fix a bug in the initilizers and a bug in BuildGeometry. This is now done | |
55 | in the same way as in AliITSv5.cxx. | |
56 | ||
9a4c6ea3 | 57 | Revision 1.6 2001/02/09 20:06:26 nilsen |
