Description
WIRED 4 is a experiment independent event display plugin module
for JAS 3 (Java Analysis Studio) generic analysis framework.
Both WIRED and JAS are written in Java.
WIRED, which uses HepRep (HEP Representables for Event Display) as its input
format, supports viewing of events using either conventional 3D projections
as well as specialized projections such as a fish-eye or a rho-Z projection.
Projections allow the user to scale, rotate, position or change parameters
on the plot as he wishes. All interactions are handled as separate edits
which can be undone and/or redone, so the user can try out things and
get back to a previous situation. All edits are scriptable by any of
the scripting languages supported by JAS, such as pnuts, jython or java.
Hits and tracks can be picked to display physics information and
cuts can be made on physics parameters to allow the user to filter
the number of objects drawn into the plot. Multiple event display plots
can be laid out on pages combined with histograms and other plots,
available from JAS itself or from other plugin modules.
Configuration information on the state of all plots can be saved and restored
allowing the user to save his session, share it with others or later continue
where he left off.
This version of WIRED is written to be easily extensible by the user/developer.
Projections, representations, interaction handlers and edits are all services
and new ones can be added by writing additional plugins.
Both JAS 3 and WIRED 4 are built on top of the FreeHEP Java Libraries,
which support a multitude of vector graphics output formats, such as
PostScript, PDF, SVG, SWF and EMF, allowing document quality output of
event display plots and histograms.
