This 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.

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/
