a7d4e65b | 10 | /// Geometry transformations can be filled in these ways: |
11 | /// - by geometry builder when geometry is built via builders | |
327d1302 | 12 | /// (this way is used when running simulation and building geometry |
13 | /// via VirtualMC) | |
14 | /// - from Root geometry file (*.root) or ASCII file (*.dat) using | |
15 | /// the method LoadGeometryData(const TString& fileName) | |
16 | /// - from geometry loaded in AliGeomManager using | |
17 | /// the method LoadGeometryData() without arguments | |
