| 17 | Since release 9.2 of Geant4, it is also possible to import geometry setups
|
|---|
| 18 | based on a plain text description, according to a well defined syntax for
|
|---|
| 19 | identifying the different geometrical entities (solids, volumes, materials
|
|---|
| 20 | and volume attributes) with associated parameters.
|
|---|
| 21 |
|
|---|
| 22 | An example showing how to define a geometry in plain text format and import
|
|---|
| 23 | it in a Geant4 application is shown in
|
|---|
| 24 | <literal>examples/extended/persistency/P03</literal>. The example also covers
|
|---|
| 25 | the case of associating a sensitive detector to one of the volumes defined
|
|---|
| 26 | in the text geometry, the case of mixing C++ and text geometry definitions
|
|---|
| 27 | and the case of defining new tags in the text format so that regions and
|
|---|
| 28 | cuts by region can be defined in the text file. It also provides an example
|
|---|
| 29 | of how to write a geometry text file from the in-memory Geant4 geometry.
