Visualising geometry
Edit your input file (test.in)
Add one line before ‘/run/beamOn 10’
/control/execute ../../examples/visVRML2FILE.in
It will produce a VRML file with the geometry (g4_00.wrl) and a VRML file with the geometry and tracks (g4_01.wrl)
To visualise these files, download visualiser (there are many, many VRML visualisers in the web..)
