5d02ea6f | 18 | Revision 1.37 2002/10/22 14:45:47 alibrary |
19 | Introducing Riostream.h | |
20 | ||
4ae5bbc4 | 21 | Revision 1.36 2002/10/14 14:57:08 hristov |
22 | Merging the VirtualMC branch to the main development branch (HEAD) | |
23 | ||
b9d0a01d | 24 | Revision 1.35.10.2 2002/08/30 15:45:54 alibrary |
25 | Adding geant4vmc support | |
26 | ||
27 | Revision 1.35.10.1 2002/06/10 17:51:15 hristov | |
28 | Merged with v3-08-02 | |
29 | ||
30 | Revision 1.35 2001/05/30 16:15:47 fca | |
31 | Correct comparison wiht AliGeant3::Class() introduced. Thanks to I.Hrivnacova | |
32 | ||
cbfdea0d | 33 | Revision 1.34 2001/05/30 15:55:35 hristov |
34 | Strings compared instead of pointers | |
35 | ||
268b9c60 | 36 | Revision 1.33 2001/05/30 14:04:31 hristov |
37 | Dynamic cast replaced (F.Carminati) | |
38 | ||
4154d3d8 | 39 | Revision 1.32 2001/03/23 00:12:23 nilsen |
40 | Set Reading of AliITSgeom data from Geant3 common blocks as the default and | |
41 | not a .det file. Removed redundent calls to BuildGeometry. | |
42 | ||
0646a0e8 | 43 | Revision 1.31 2001/02/13 16:53:35 nilsen |
44 | Fixed a but when trying to use GEANT4. Needed to replace | |
45 | if(!((TGeant3*)gMC)) with if(!(dynamic_casst<TGeant3*>(gMC))) | |
46 | because just casting gMC to be TGeant3* even when it realy is a TGeant3 pointer | |
47 | did not result in a zero value. For AliITSv5asymm and AliITSv5symm, needed | |
48 | to fix a bug in the initilizers and a bug in BuildGeometry. This is now done | |
49 | in the same way as in AliITSv5.cxx. | |
50 | ||
9a4c6ea3 | 51 | Revision 1.30 2001/02/09 20:06:26 nilsen |
