• Interactivity Framework (environment) :

– IFK = UI + Vis + Scripting

Interactivity

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) ?

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

We must do an effort to have G4IFK workingon experiments data.

• 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.
