[Gate-users] G4OpenGLXViewer problem

Wed Aug 28 23:43:13 CEST 2013

Hi again,

I have the same problem and the proposed solution also did not quite work for me.

Instead, it's probably better to use the Qt viewer. If you've installed Gate and Geant with Qt, then you can simply launch Gate this way:

>Gate --qt

The Qt viewer allows you to set up a GUI with commands. Here are the standard commands that I use everytime I launch Gate with Qt:

# draws the window with the box
/vis/open OGL 600x600-0+0
# draws the scene tree
/vis/drawVolume

#
# Viewer menu :
/gui/addMenu viewer Viewer
/gui/addButton viewer "Rebuild geometry" "/gate/geometry/rebuild"
/gui/addButton viewer "Set style surface" "/vis/viewer/set/style surface"
/gui/addButton viewer "Set style wireframe" "/vis/viewer/set/style wire"
/gui/addButton viewer "Refresh viewer" "/vis/viewer/refresh"
/gui/addButton viewer "Update viewer (interaction or end-of-file)" "/vis/viewer/update"
/gui/addButton viewer "Flush viewer (= refresh + update)" "/vis/viewer/flush"
/gui/addButton viewer "Update scene" "/vis/scene/notifyHandlers"
#
/gui/addMenu zoom Zoom
/gui/addButton zoom "10%" "/vis/viewer/zoomTo 0.1"
/gui/addButton zoom "50%" "/vis/viewer/zoomTo 0.5"
/gui/addButton zoom "100%" "/vis/viewer/zoomTo 1.0"
/gui/addButton zoom "150%" "/vis/viewer/zoomTo 1.5"
/gui/addButton zoom "200%" "/vis/viewer/zoomTo 2.0"
/gui/addButton zoom "500%" "/vis/viewer/zoomTo 5.0"

#
#	W O R L D
#
/gate/world/geometry/setXLength 150. cm
/gate/world/geometry/setYLength 150. cm
/gate/world/geometry/setZLength 150. cm

/gate/geometry/setMaterialDatabase /Applications/gate_v6.2/GateMaterials.db

/vis/scene/add/axes 

I would suggest you make a macro file out of those commands and execute it everytime you launch Gate with Qt.

Be aware that if you run your simulation with the Qt viewer open, the GUI will become unresponsive because of the single-threaded nature of the application.

Hope this helps!

Marc
