1 | First steps : |
---|
2 | ----------- |
---|
3 | Click in 'Geant4/init' to initialize Geant4 |
---|
4 | for this example. This execute the script : |
---|
5 | <package>/<version>/scripts/Geant4/init.g4m |
---|
6 | |
---|
7 | Note that any action in the GUI triggers interpreted |
---|
8 | scripts (Python, Geant4 intercoms,...) |
---|
9 | |
---|
10 | Click in 'Geant4/Detector' to visualize some geometry. |
---|
11 | |
---|
12 | Click in 'Geant4/Geant4/Run...' to map the Run dialog box. |
---|
13 | |
---|
14 | Click in Apply to start a run. |
---|
15 | |
---|
16 | After each event, control is given to the GUI. |
---|
17 | Someone can play with the Inventor viewer controls |
---|
18 | to manipulate the scene. |
---|
19 | |
---|
20 | Click in 'Geant4/Geant4/Next evt' to return to Geant4 |
---|
21 | to produce a new event. |
---|
22 | |
---|
23 | By default, the command prompt is set to Geant4 |
---|
24 | commands. Try for example : |
---|
25 | G4> /gun/direction 1 0 0 |
---|
26 | to change the "gun" direction. |
---|
27 | |
---|
28 | Geometry viewing : |
---|
29 | ---------------- |
---|
30 | Click in 'Tree/PVs' to display the geometry |
---|
31 | hierachy in the tree widget (the one at the |
---|
32 | left of the viewer). |
---|
33 | |
---|
34 | Choose an item in the tree to visualize it. |
---|
35 | |
---|
36 | Using trajectories timed mode : |
---|
37 | ----------------------------- |
---|
38 | To change time slicing of the trajectories : |
---|
39 | |
---|
40 | Python> node = region_findSoG4Trajectories() |
---|
41 | Python> node.set('timeInterval 0.05') |
---|
42 | Python> node.set('timeSteps 200') |
---|
43 | Python> node.set('timeStart 0') |
---|
44 | |
---|
45 | To have some traceback : |
---|
46 | |
---|
47 | Python> node.set('verbose TRUE') |
---|
48 | |
---|
49 | To see current values : |
---|
50 | |
---|
51 | Python> iv_dumpNode(node) |
---|
