Detector visualization with Panoramix

Panoramix

Purpose of PanoramixPanoramix provides Interactive Data Visualization in LHCb

Provides a set of basic menus and commandIt allows to explore the detector tree and visualize itIt allows to explore and visualize the eventsOnline and Offline views, including MC truth information

It can be controlled and customized in different ways allowing complex views

OnX menu, Callbacks, Pythons scripts

It depends on all of the LHCb components projectsGAUDI, LHCB, LBCOM, REC, PHYS, STRIPPING [,ONLINE]

2Simulation Tutorial - Feb. 2012

In this tutorial

highlight only the

functionality related

to detector geometry

Panoramix

Running PanoramixYou can run a local installation of Panoramix on your own machine (this will be faster)

Look at the Introduction to Panoramix tutorial for instructions on how to install the application locally

To run using an already existing installation

3Simulation Tutorial - Feb. 2012

SetupProject Panoramix v20r2python $myPanoramix --BareConfig 1 –f none -v MyOwnOptions.py

Start with bare configuration for GUI only

No event file, only detector geometry

User options file

from Configurables import LHCbAppLHCbApp().DDDBtag = "MC11-20111102"LHCbApp().CondDBtag = "sim-20111111-vc-md100"LHCbApp().Simulation = True

To see possible arguments

python $myPanoramix –h
