FullSimLight is a lightweight, Geant4-based command line
simulation utility intended for studies of simulation performance. It
is part of the GeoModel toolkit ( which has been
stable for more than one year. The FullSimLight component
has recently undergone renewed development aimed at extending its
functionality. It has been endowed with a GUI for fast, transparent,
and foolproof configuration and with a plugin mechanism allowing users
and developers with diverse goals to extend and customize the
simulation. Geometry and event input can be easily specified on the
fly, allowing rapid evaluation of different geometry options and their
effect on simulation performance. User actions and sensitive detectors
can also be loaded through the new plugin mechanism, allowing for
customization of Geant4 processing and hit production. The geometry
explorer (gmex), in a parallel development, has been enhanced with
the capability of visualizing FullSimLight track and hit output.
FullSimLight, brought to you by the ATLAS collaboration, is an
experiment independent software tool.
