Interactivity

• Interactivity Framework (environment)
• IFK UI Vis Scripting

Geant4 interactivity

• Kernel global, geometry, persistency, track,
  tracking, run, processes, materials, particles,
  event, digitshits, readout, intercoms.
• Interactivity intercoms, interfaces,
  visualization, graphics_reps.
• Naruto clarify intercoms role
• Kernel software bus between categories (best
  solution ?).
• Interactivity command interpreter.
• What happens if we want to move to another
  scripting system (tcl, cint, python, java) ?

IFK multiplicity

• G4IFK intercoms, interfaces, visualization,
  graphics_reps, modeling
• come without data analysis tools of its own.
• OPACS, OpenScientist/G4Lab, WIRED,JAS, ROOT
• come with data analysis tools
• Explorer, GNOME,...
• LHCb_IFK, CMS_IFK, Atlas_IFK, ... man power
  will migrate to these IFKs

Experiment kernel
We must do an effort to have G4IFK working on
experiments data.

G4IFK Issues

• G4IFK (intercoms, interfaces, vis) reusable on
  experiments geometries and data ?
• When are we going to have
• GUI and Vis/Viewers intergration ?
• Easy GUI building / customization.
• GUI/Tree for DTREE.
• Picking over geometry and data.
• Data selection from scripting.
• Easy 3D navigation.
• Driving Geant4 from other scripting languages.
• Study heavy loaded graphic (thousands of volumes,
  hits,).
• Testing.
