geomD0.C File Reference

Detailed Description

Script drawing a detector geometry (here D0).

by default the geometry is drawn using the GL viewer Using the TBrowser, you can select other components if the file containing the geometry is not found in the local directory, it is automatically read from the ROOT web site.

  • run with .x geomD0.C top level detectors are transparent
  • or .x geomD0.C(1) top level detectors are visible
