[Gate-users] Geometry Visualization

[Marc Chamberland]

That looks fine to me. I don’t know if you should see the world dimensions or not, frankly.

Build your whole detector, then try to visualize it with the command:

/gate/geometry/rebuild

Let’s see what that gives you.


Also, you could try running Gate with the Qt visualization:

http://wiki.opengatecollaboration.org/index.php/Users_Guide_V7.0:How_to_run_Gate#Running_GATE_in_Qt_mode

You would need to make sure Gate is compiled with the Qt option, though. Again, see the User’s Guide for more details.


Cheers,
Marc

Hello Marc,

Thank you for pointing me out to the visualization guide.

To test the visualization I did the following

In terminal window I execute:

Gate

Idle> /vis/open                           OGL
/vis/viewer/set/viewpointThetaPhi   60 60
/vis/drawVolume
/tracking/storeTrajectory           1
/vis/scene/add/trajectories
/vis/scene/endOfEventAction         accumulate



/gate/geometry/setMaterialDatabase ../GateMaterials.db

/gate/world/geometry/setXLength 4. m
/gate/world/geometry/setYLength 3. m
/gate/world/geometry/setZLength 4. m
/gate/world/setMaterial Air

/gate/world/daughters/name CTscanner
/gate/world/daughters/insert box
/gate/CTscanner/placement/setTranslation 0. 0. 150.5 mm
/gate/CTscanner/geometry/setXLength 50. mm
/gate/CTscanner/geometry/setYLength 50. mm
/gate/CTscanner/geometry/setZLength 1. mm
/gate/CTscanner/setMaterial Air
/gate/CTscanner/vis/forceWireframe
/gate/CTscanner/vis/setColor white


The result of the visualization is attached.

Is it normal? Shouldn't I see my world dimensions?

Cheers,

Andre

Hi Andre,

Please read the User’s Guide carefully:

http://wiki.opengatecollaboration.org/index.php/Users_Guide_V7.0:Visualization


For example:

"The best method is to let Geant4 choose the best OpenGL mode with /vis/open OGL"

And:

"(…) manual geometry update has to be used instead. This can be done using the following command at any moment in the GATE command prompt environment:

/gate/geometry/rebuild

Otherwise the complete geometry building is done when /gate/run/initialize command is given."


Cheers,
Marc
