| 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) |
|---|
