VP1 Screenshots

ATLAS events!

You can find the latest public ATLAS event displays here. Among them you can find many official event displays created with VP1; for example this 4 muons Higg's candidate event or this 2 muons plus 2 electrons one.

First Beam Images!

• Find images from the first beam on September 10th 2008 here!
• Find images and movies of a particularly nice beam halo event (run87863/evt1450) here

VP1 upon startup

• No plugins are loaded by default upon startup. This must be done through the menu's, but some (hopefully) friendly text and quick-start buttons makes this easy for common use-cases:
  
  
  
  

Geometry Channel

• Automatic and direct view of the Atlas geometry as defined in GeoModel. A few phi-sectors have been hidden to allow easy examination of the inner detectors:
  
  
  
  
• Holding down one of ctrl/shift and z buttons while clicking one volumes allows one to navigate through the geometry, e.g. expanding volumes to show their daughters. A browser on the left allows one to see the entire GeoModel tree as it exists in memory (volumes not currently displayed in the 3D view are grayed out):
  
  
  
  
• Depending on the chosen settings, various information useful for debugging of the geometry-description is printed out upon selection of volumes:
  
  
  
  

Track Channel

• Global tracking view. Muon chambers geometry adapt automatically to event data.
  
  
  
  
• View of the inner detector, with projection of TRT drift-circles:
  
  
  
  
• Clicking on a muon chamber (or data within), automatically causes the view to reorient itself to view the chamber "head on". Note how the PRD's gets coloured by the tracks that uses them.
  
  
  
  
• Change one checkbox in the geometry controller, and we show all tubes, with the data projected at the end:
  
  
  
  
• Or click another checkbox and get the chambers shown in a more idealistic view:
  
  
  
  
• Not only tracks, but also segments can be shown:
