Guide lines
Logical and consistent use of ‘metaphors’ for particle properties
Same representation in 2D- and 3D-graphics
PART 1 :
GRAPHICAL REPRESENTATION OF “INVISIBLE” OBJECTS
Object library for use in future graphics / animations
Appealing appearance - (even) for non-physicists

Example: Many ways to represent a proton
....without or with gluons
how to represent electrons, neutrinos?Strong vs weak, electromagnetic charge?Spin 1/2 vs Spin 1 ?
....quarks visible or not
....without or with sea quarks

OTHER TOPICS (priority to be defined)
Matter-Antimatter asymmetry in Bd decay
Energy becomes mass - particles and antiparticles at CERN
Extra dimensions and black holes
Dark Matter - how we know it is there, how to find it at CERN
Supersymmetry: what is - and why we think we need it
Particle detectors - how they work, how they are used(Si strips, pixels, tracking; calorimeters; RPC, drift tube, CSC, alignment/calibration)
Gauge symmetries and heavy bosons (old and new), Z’Compositeness (preons)Technicolor (composite Higgs, techni-particles)4th Generation

ANIMATION GROUP : Work flow
PHASE 1 - DEVELOPMENT: Conceptualization (brainstorming), script
PHASE 2 - PRE-PRODUCTION : Story board, animatic (rough animated version), design chart
PHASE 3 - PRODUCTION: Modeling, materials, shaders, textures; layouts, animations, lighting
PHASE 4 - POST-PRODUCTION: Final rendering, compositing (layers), editing, sound, credits
