|
|---|
| 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.
