Example of use GDML reader/writer in Detector Construction
-----------------------------------------------------------
In this directory you can find a example showing how to use GDML module for
reading and writing. It is also shown how to Read STEP Tools files.
In this example the DetectorConstruction consists of a Simple Detector, then
this Detector is filled/written in GDML.
The different options for writing and reading GDML files are shown in the
Detector Construction: writing modular files, using different schema location,
setting parameters for names in GDML file, etc.
For more information, please, refer to the GDML Documentation.
The Geometry is a Simple Detector Box with 4 Subdetectors.
This setup shows how to use Reflection Factory, Assembly of Volumes and
Parameterisation.
Using commands or macros it possible to read or write GDML file.
HOW TO BUILD THE EXAMPLE ?
- You need to have built the persistency/gdml module by having
set the -DGEANT4_USE_GDML=ON flag during the CMAKE configuration step,
as well as the -DXERCESC_ROOT_DIR=<path_to_xercesc> flag pointing to
the path where the XercesC XML parser package is installed in your system.
- Compile and link to generate the executable (in your CMAKE build directory):
% make
- Execute the application:
% geotest [macro-file].mac
You can run this application with the following macro file:
write_gdml.mac : This macro will write the Geometry defined in file
"test.gdml" and output to a new file wtest.gdml
To change this name you can use command :
/mydet/writeFile FileName.gdml
read_gdml.mac : This macro will read the Geometry from file "test.gdml"
To change this name you can use command :
/mydet/readFile FileName.gdml
read_step.mac : This macro will read the STEP Tool files "mbb.geom" and
"mbb.tree" and load them in memory.
To change this name you can use command :
/mydet/StepFile FileName
