3. G.Barrand, LAL-Orsay Interactivity Framework (environment) : – IFK = UI + Vis + Scripting Interactivity

4. G.Barrand, LAL-Orsay Kernel : global, geometry, persistency, track, tracking, run, processes, materials, particles, event, digits+hits, 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) ? Geant4 interactivity

6. G.Barrand, LAL-Orsay 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

9. G.Barrand, LAL-Orsay 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.
