Example clGeometry
|
|
--------------------
|
|
|
|
This examples demonstrates the usage of the g3tog4 tool for converting
|
|
Geant 3.21 simple geometries to Geant4 ones.
|
|
|
|
It requires Geant4 installation with G3toG4 library (
|
|
handled with GEANT4_USE_G3TOG4 option in CMake build or the G4LIB_USE_G3TOG4
|
|
environment variable in GNUmake build).
|
|
|
|
It demonstrates building a detector geometry using the call list
|
|
mechanism and also provides visualization, see the G3toG4DetectorConstruction
|
|
class. The executable is provided in clGeometry.cc.
|
|
|
|
The example uses the GunPrimaryGeneratorAction class from the extended examples common
|
|
repository available in common subdirectory. This class is instatiated in G3toG4ActionInitialization class as it is required for processing with both sequential and multi-threaded Geant4 modes.
|
|
|
|
To run the application, one must provide as input argument a call list file
|
|
(few test samples are placed in data directory), generated by the rztog4 application
|
|
which can be built typing "make bin" from $G4INSTALL/source/g3tog4.
|
|
Then several optional arguments can be specified to define a macro, UI session
|
|
or number of threads (applicable only with multi-threading mode):
|
|
|
|
clGeometry callListFile [-m macro ] [-u UIsession] [-t nThreads]
|
|
|
|
There is provided clGeometry.in macro which can be executed either interactively
|
|
or in batch.
|
|
|
|
For example:
|
|
> clGeometry data/testmodel.dat -m clGeometry.in
