## 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 |
