Hello I am a first year college physics student and I want to setup the display of a simplified detector/particle tracking system. The script I describe below ran into a snag and as I am in the initial stages of learning the ROOT package, I could use some help.
My intent is to display a cylindrical geometry and a few random particle tracks, however the attached script is not rendering my cylinder, only the particle tracks. (see attached script => pbr_4trk.C (3.1 KB) , and output => pbr_4trk-output.txt (2.5 KB) , and geometry file => CylGeo.root (7.5 KB) )
Specifically the Event Manager is issuing this message:
‘’’ EVEMNG … streaming scene [Geometry scene]
sending json, len = 634
NOT sending binary, len = 0 ‘’’
and even in the Event Visualization Environment I am unable to toggle the view on.
I am certain there are more efficient ways of approaching this, please feel free to recommend a completely different approach. Since I am at the very ground level (I read the Basic-Course slides, perused the Class Reference Docs, etc.) any specific suggestions, or brief general pointers to put me on the right track are appreciated.
Additional point: as you can see, I am saving my geometry to file, but I can see that the object is already present in the ROOT browser. What would be a way of referencing it directly without having to go through the saving and rereading step?
Thank you for you time!
