0003 Example of use GDML reader/writer in Detector Construction
0004 -----------------------------------------------------------
0005
0006 In this directory you can find a example showing how to use GDML module for
0007 reading and writing. It is also shown how to Read STEP Tools files.
0008 In this example the DetectorConstruction consists of a Simple Detector, then
0009 this Detector is filled/written in GDML.
0010 The different options for writing and reading GDML files are shown in the
0011 Detector Construction: writing modular files, using different schema location,
0012 setting parameters for names in GDML file, etc.
0013 For more information, please, refer to the GDML Documentation.
0014
0015 The Geometry is a Simple Detector Box with 4 Subdetectors.
0016 This setup shows how to use Reflection Factory, Assembly of Volumes and
0017 Parameterisation.
0018 Using commands or macros it possible to read or write GDML file.

0020 HOW TO BUILD THE EXAMPLE ?
0021
0022 - You need to have built the persistency/gdml module by having
0023 set the -DGEANT4_USE_GDML=ON flag during the CMAKE configuration step,
0024 as well as the -DXERCESC_ROOT_DIR=<path_to_xercesc> flag pointing to
0025 the path where the XercesC XML parser package is installed in your system.
0026
0027 - Compile and link to generate the executable (in your CMAKE build directory):
0028 % make
0029
0030 - Execute the application:
0031 % geotest [macro-file].mac
0032
0033 You can run this application with the following macro file:
0034
0035 write_gdml.mac : This macro will write the Geometry defined in file
0036 "test.gdml" and output to a new file wtest.gdml
0037 To change this name you can use command :
0038 /mydet/writeFile FileName.gdml
0039
0040 read_gdml.mac : This macro will read the Geometry from file "test.gdml"
0041 To change this name you can use command :
0042 /mydet/readFile FileName.gdml
0043
0044 read_step.mac : This macro will read the STEP Tool files "mbb.geom" and
0045 "mbb.tree" and load them in memory.
0046 To change this name you can use command :
0047 /mydet/StepFile FileName
