The ICA laboratory develops, under the direction of Annie Luciani, physical objects models and various phenomenons :
Deformable materials models / complex rigid structure / collective phenomenons / granular materials / liquid materials
Elastic, plastic etc. (Phd student Matthieu Evrard)
Danced movements models

Working on the basis of a dynamic phenomena typology relevant to the eye, ICA Laboratory develops physically-based object models in its Image Workshop under the supervision of A. Luciani. A few examples :
Rigid objects, articulated rigid objects
Vehicles, puppets, clockworks (cf. Jimenez, Chanclou, Nouiri, Marquet)
Deformable and variable topology objects
Volumic and lineic solids, fabrics, skins, ... (cf. Jimenez, Godard, Berger)
Fluids, pastes, granular materials, ... (cf. Manzotti, Rifai, Juneidi)
Natural, chaotic and collective phenomena
Natural, heterogeneous, and plastic surfaces, smoke, wind, sand (cf. Vapillon, Plasson, Chanclou)
Crowds and collective behavior... (cf. Seminel, Tixier)
(One of the key aspects of this method is the concept of model design : all the studied models are based on the same formalism)
An important part of work done at the Image Workshop is studying the interaction between shape and motion models for complex dynamic phenomena such as important deformations and evolutive or chaotic phenomena (turbulences, avalanches, ...) A visualization method called the "Engraved Screen" ("écran d'épingle") was developed (cf. Habibi), based on the "phyxel" notion (physical element) : the visualization surface matches with a physical surface, which can be reshaped under the action of a particle object. Its generates forms by implicit dynamic volumes whose profile and density depend on the dynamics of particle objects, sources of movement.
January 1997 — Visualization of smoke with the "Engraved Screen" method.
June 1997 — Unique model of sands-pastes-foams-fluids.
June 1998 — Physically-based model of a crowd going through a lock chamber & Image and sound model of a manipulable puppet.
