Event Dsiplay [message #8076] Sun, 15 March 2009 18:59 Go to next message
Anonymous Poster From: *pool.einsundeins.de
Hi,

I am looking for some way to do an event visualization. I remember that there has been something implemented in PANDAROOT. Can anybody give me a hint on how to run an example? I tried, but the macro run/run_sim_vis.C, but that crashed with the following output. Does anybody have an idea?

Thanks, Christian

Hello Christian,

Depending on what you want to see, you should have a look at the eventdisplay.
A sample is macro/mvd/Tracking/eventDisplay.C.
Be sure to switch on the storage of trajectories in the simulation if you want to see the MC tracks.

For the geometry visualisation I recommond to set the vis level in the gui to 10. Seeing an event works by selecting the eventmanager object and increasing the event number in the info tab.

Kind regards, Ralf.
