Data

Initial goal: take a simple tt fully simulated event look at it with the various graphics packages

evaluate performances

BUT…. The 3 packages requires DIFFERENT data format

GraXML .xml

WIRED .heprep.xml

Atlantis .*lafa*, .*lafb*, .*LAFb*

Converter xml -> heprep.xml not available

Possible to convert to Atlantis format (but to old one)

Data pool found in:

/afs/cern.ch/atlas/project/Atlantis/loomis/events/

Several events (3 directories for GraXML, WIRED and Atlantis format)

Only one event available in the 3 formats (with different names..)

Event_Y27346.151.2.xml (GraXML) Event_Y27346.151.2.heprep.xml (WIRED)

Atlantis_lafa_60 (Atlantis)

GraXML Test setup

Setup instructions Follow http://atlas.web.cern.ch/Atlas/GROUPS/GRAPHICS/Texts/Documentation/GraXML/#How to Start Instructions:$ sh$ cd [swinstallpath]$ . ./setup.sh$ ./GraXML.sh Examples/EndcapEvent.xml

References:http://atlas.web.cern.ch/Atlas/GROUPS/GRAPHICS/

Texts/Documentation/GraXML for sw, and atlas xml events

Clearly done for a 3-D representation of objects or for VERY simple events and detector description

Not suitable for complex events (program does not even succeed to read them)

Slow with used setup (expecially TRT)

Enough user friendly (info on WEB quite clear)

Nice windows setup

Inner detector + muon implemented

Some points to be improved...

Window stays in the corner andcannot be controlled!

Too slow to apply a selection!

Option which should be a default!

TreeView

What is for?Tracks info superimposed

Colours randomly chosen

Sometimes all display comesout with the same tone!

User cannot associate colours with elements without changing and recompiling corresponding class

Some other small problems…:

Did not succeed to print out a jpg file of the display (comes out only a gray figure)

Also: one cannot choose where to put the output file

Event or elements cannot be de-selected immediately after selection (you need to click once elsewhere)

Picking elements does not always work properly

Each new file requires to re-open the program

events

Can do everything provided you know how to do it !

Files of instructions on how to get started not enough

On-line help useful when you have already some hints

At the moment is the most complete program but needs tutorial from expert (unless you enjoy riddles)

3 hours of “phone-tutorial” given by H. Drevermann

“Philosophy” behind clearly driven by physics (this experience should not be lost!)

Nice features:

•Pre-defined window sets

•Not space-consuming menu (displays take most of the screen)

•Appealing graphics style (colours, lines, marks...)

•Tracks info colour linked with tracks colour

•Possibility of two-letters command strings

To be improved:

•Picking sometimes is not trivial

•Default -z view too busy

Filter on Pt and d0 applied

Tracks with high d0and at distance to the event z-vertex

Wired InstallationVersion 2.2(27 Apr 01)tested on PC/Win2000 Ver. 2 rapidly evolving

April 27th 2001 - Version 2.2 released, including a tutorial April 4th 2001 - Version 2.1 released, compatible with JAS 2.2.3 March 30th 2001 - Version 2.1 delayed until the JAS 2. 2.3 release. March 9th 2001 - Version 2.0.1 released, with bug fixes and new features

January 26th 2001 - Version 2.0 released.

Installation instructions Follow http://wired.cern.ch Instructions to run Wired as a plug-in module inside JAS (Java Analysis Studio). You need:– jdk1.3.0_02 from http://java.sun.com/j2se/1.3/– JAS2.2.3 from http://www-sldnt.slac.stanford.edu/jas/downloads.htm– http://wireddoc.web.cern.ch/wireddoc/releases/2.2/wired-jas-plugin.jar

Wired Test setup

Wired as a JAS extension: Run JAS, in Menu Job/Load Plugin enter Class

hep.wired.WiredPlugin

(for Wired 2.0.1 or previous enter Class: hep.wired.graphics2d.App instead)

evts

/afs/cern.ch/atlas/project/Atlantis/loomis/events/wired for events

Great improvement with the latest version. Many functionalities now available (i.e : picking, Z-vertex finding, filter for tracks and hits, hits grouping, V-plots etc..).

Definitely user-friendly (and good PDF manual to start with)

Goes in the same direction of Atlantis for what concern functionalities ( on the other end, Atlantis is going to appear in a Java version, using a significant portion of the Wired FreeHep library.....)

Nice features:

•Objects once selected appear coloured in all windows (all the rest turn grey)

To be improved:

•Control menu takes too much space (displays are sacrificed)

•Windows to be adjusted

•Default graphics style not optimised (colours, lines, marks)

•Not all views yet implemented

•Automatic Z-vertex calculation not implemented

•Selected tracks sometimes covered by grey ones

Full event

Preliminary conclusions

Although publicly available information is sometimes not enough, developers very friendly and willing to help

Maybe to soon to make a final “physics-oriented” evaluation: packages are in continuous development, more or less only inner detector is present

However regular monitoring and Feed-back between graphics developers and users (physics groups) useful.

Two efforts (Atlantis in Java and WIRED) going on in parallel. Need coordination
