<LI>A new command, <TT>/vis/scene/endOfRunAction</TT>, has been implemented.
|
|
The default behaviour is "refresh". In the case when
|
|
<TT>endOfEventAction</TT> is "accumulate", it causes systems requiring
|
|
post-processing, such as DAWN, or file-based systems, such as DAWNFILE
|
|
and HepRep, to show the view (equivalent to <TT>/vis/viewer/update</TT>)
|
|
at the end of run and screen-based systems, such as OpenGL, to clear the
|
|
tracks. hits, etc., at the start of the next run. Usually this is the
|
|
desired behaviour.<BR>
|
|
The user will find that it is no longer needed to issue
|
|
<TT>/vis/viewer/update</TT> (or <TT>/vis/viewer/flush</TT>) at the end
|
|
of a run. To revert to the old behaviour, one should issue the command
|
|
<TT>/vis/scene/endOfRunAction accumulate</TT>.</LI>
|
|
<LI>The OPACS graphics driver has been removed since that graphics
|
|
system has been superseded by
|
|
<A TARGET="ext" HREF="http://www.lal.in2p3.fr/OpenScientist">OpenScientist</A>.</LI>
|
|
<LI>A new HepRep driver has been added, producing files suitable for viewing
|
|
with the <A TARGET="ext" HREF="http://wired.freehep.org">WIRED event display</A> (or
|
|
other HepRep clients).<BR>
|
|
The previous HepRep driver that produced HepRep version 1 files
|
|
from <TT>/vis/open HepRepFile</TT> is still supported.
|
|
But a new driver producing HepRep version 2 files is now available
|
|
from <TT>/vis/open HepRepXML</TT>.<BR>
|
|
The newer HepRep format allows the WIRED event display to give you greater
|
|
control over visibility of various event and detector components.
|
|
It will also set the stage for many improvements to come in later versions
|
|
of WIRED (such as the ability to edit and save attribute changes from the
|
|
event display client and have these changes apply to subsequent Geant4
|
|
images that one reads, and the ability to adjust visibility based on cuts
|
|
on attributes such as energy and momentum).<BR>
|
|
<TT>/vis/open HepRepXML</TT> provides the following other additional
|
|
benefits over <TT>/vis/open HepRepFile</TT>:
|
|
<UL>
|
|
<LI>More compact files (by better hierarchical handling of repeated
|
|
attributes).</LI>
|
|
<LI>Ability to save individual events directly to gzipped files.</LI>
|
|
<LI>Ability to save multiple events to a single zip file.</LI>
