Gabriele CosmoThis G4 Graphics Driver creates a HepRep File suitable for viewing by the WIRED Event Display client. It requires no external packages. The HepRep graphics format is further described at http://heprep.freehep.org Two different drivers area available for either HepRep1 or HepRep2. Driver: HepRepFile ------------------ The version of HepRep produced by this driver is HepRep Version 1. Each call to /vis/viewer/update rewrites the file G4HepRep.xml. View the file using the WIRED Event Display, available from: http://www.slac.stanford.edu/BFROOT/www/Computing/Graphics/Wired/ WIRED can read xml files in zipped format as well as unzipped, so you can save space by applying gzip to the xml file. This will reduce the file to about five percent of its original size. Joseph Perl 9 November 2001 Driver: HepRepXML ----------------- The version of HepRep produced by this driver is HepRep Version 2. To set the base part of the filename (filename = basefilename-seqno.heprep): /vis/scene/create basefilename To route the HepRep XML output to stdout (or stderr) use: /vis/scene/create stdout To select the driver /vis/open HepRepXML Any call to draw part of an event will open the file and start writing. Each file, apart from stdin/stderr, is closed by: /vis/viewer/flush (WARNING: files will not contain geometry if not flushed. G4 exit will only close file) Multiple events can be written by: /vis/scene/endOfSceneAction accumulate View the file using the WIRED Event Display, available from: http://www.slac.stanford.edu/BFROOT/www/Computing/Graphics/Wired/ or in future http://wired.freehep.org 9 Dec 2002 Mark Donszelmann
