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. |
---|
