|---|
| 13 | This scripts offers the choice of visualization systems; |
|---|
| 14 | one among OGLSX (OpenGL stored mode), or VRML2FILE or Wired3. |
|---|
| 15 | |
|---|
| 16 | OGLSX is the default viewer and you need no environment variables. |
|---|
| 17 | |
|---|
| 18 | To use VRML2FILE you have to specify its viewer which is found in your |
|---|
| 19 | search path and the destination directory where *.wrl file is stored. |
|---|
| 20 | If you don't specify the name of the viewer, you can't choose it on the panel. |
|---|
| 21 | For example, |
|---|
| 22 | setenv G4VRMLFILE_VIEWER $HOME/bin/vrmlview |
|---|
| 23 | setenv G4VRMLFILE_DEST_DIR $HOME/tmp/ <= terminate with / |
|---|
| 24 | |
|---|
| 25 | To use Wired, download it and install under your directory. Java Runtime |
|---|
| 26 | Environment is necessary. |
|---|
| 27 | Then set, for example; |
|---|
| 28 | setenv G4HEPREPFILE_VIEWER $HOME/Wired/bin/wired <= any path you use |
|---|
| 29 | setenv G4HEPREPFILE_DIR $HOME/tmp/ |
|---|
| 30 | setenv G4HEPREPFILE_NAME lesson2_00 <= any name you choose. |
|---|
| 31 | setenv G4HEPREPFILE_OVERWRITE 1 <= to reuse the file for "next event" |
|---|
| 32 | G4HEPREPFILE_VIEWER isn't an official Geant4 environment variable but is employed |
|---|
| 33 | here to control the vissssualization viewers. |
|---|
| 34 | The name of the HepRepFile is ${G4HEPREPFILE_NAME}.heprep which will be |
|---|
| 35 | stored in ${G4HEPREPFILE_DIR}. |
|---|
| 36 | |
|---|
| 37 | ExN03.py script don't use VRML or Wired if their *_VIEWER isn't set. |
|---|
| 38 | But other env variables are also used in the script to look for the |
|---|
| 39 | file and to activate the viewer, you have to set all of the above variables |
|---|
| 40 | in the shell where you activate ExN03.py script. |
|---|
| 41 | |
|---|
| 42 | |
|---|
| 43 | NOTICE) VRML viewer blocks the window (modal), so that you have to exit it to |
|---|
| 44 | display another run. |
|---|
| 45 | |
|---|
| 46 | ********* ExN03.py script *********** |

| 48 | This example id derived from examples/novice/N03. |
|---|
| 49 | You can |
|---|
| 50 | - choose the materials of absorber and gap |
|---|
| 51 | - set the thickness of the absorber and gap |
|---|
| 52 | - set the lateral (in YZ plane) size of the sandwitch cal. |
|---|
| 53 | - choose an incedent particle |
|---|
| 54 | - set its energy |
|---|
| 55 | - set the number of events to run |
|---|
| 56 | - toggle on/off of the electromagnetic processes |
|---|
| 57 | - set cut length |
|---|
| 58 | - set magnetic field |
|---|
| 59 | - typein any Geant4 command (except related with the above functions) and execute it |
|---|
| 60 | |
|---|
| 61 | How to run it? |
|---|
| 62 | %python ExN03.py |
|---|
| 63 | |
|---|
| 64 | You can visualize with OpenGL stored mode or VRML or Wired3 |
|---|
| 65 | You can choose either of the active viewers by pushing the |
|---|
| 66 | radio buttons. |
|---|
| 67 | ========================= |
|---|
| 68 | NOTICE) |

| 72 | another viewer. |
|---|
| 73 | |
|---|
| 74 | Wired has the "next"/"previous" event button. So to see the next |
|---|
| 75 | event, first run and then "next" event. Wired doesn't block G4 |
|---|
| 76 | and you can have Wired and OGLSX both open. |
