## GDML DETECTOR SENSITIVITY
|
|
|
|
This example demonstrates the usage of the GDML auxiliary information for
|
|
associating a sensitive detector to a volume.
|
|
|
|
The detector construction consists of a call to GDMLProcessor which parses a
|
|
GDML file and returns the pointer to the world volume. The user can also write
|
|
her/his own GDML file and use it as the primary input format for her/his Geant4
|
|
application.
|
|
|
|
A simple GDML files is provided:
|
|
- auxiliary.gdml, showing association of a volume with the auxiliary
|
|
information, related to the sensitive detector.
|
|
|
|
## 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 for parsing interactively the GDML file:
|
|
```
|
|
% ./gdml_det auxiliary.gdml
|
|
```
