Section: New Results

Applications covered by this year's results

The above sections presented our research in terms of fundamental tools, models and algorithms. A complementary point of view is to describe it in terms of application domains. The following sections describe our contribution to each of these domains, with references to the tools we relied on if they were already presented above.

Interactive modeling systems

Participants : Grégoire Aujay, Marie-Paule Cani, Paul Kry, Adeline Pihuit, Jamie Wither.

Several of the tools we are developing are devoted to a new generation of interactive modeling systems:

Synthesis of natural scenes

Participants : Antoine Bouthors, Eric Bruneton, Marie-Paule Cani, Mathieu Coquerelle, Philippe Decaudin, Cédric Manzoni, Xing Mei, Fabrice Neyret, Qizhi Yu.

Many of the diverse fundamental tools we are developing (see Sections 6.2.4 , 6.2.5 , 6.3.3 , 6.3.4 and 6.3.5 ) are contributing to the long term, general goal of modeling and animating natural scenes. They can be combined to allow the large scale specification, efficient rendering and animation of landscapes (rivers and cloudy skies, etc). The synthesis of complete natural sceneries is one of the aims of the NatSim project (see Section  8.2.2 ).

Medical applications

Participants : Michael Adam, Marie-Paule Cani, Florent Falipou, François Faure, Sahar Hassan, Frank Hetroy, Matthieu Nesme, Olivier Palombi, Adeline Pihuit.

Some of our work on geometric modeling and physically-based animation has been successfully applied to the medical domain:

Our tools for efficient physically-based simulation, and in particular our new contributions to collision detection and response (see Section  6.2.1 ), is being used in a new European medical project called Odysseus (see Section  8.1.2 ).

Furthermore, Mathieu Nesme's PhD research (see Section  6.2.2 ), which is co-advised by Yohan Payam of laboratory TIMC, concentrates on the development of improved models for human tissue simulation for surgical simulations.

Animation of virtual creatures

Participants : Marie-Paule Cani, Christine Depraz, François Faure, Franck Hétroy, Lionel Reveret.

Several of our new models and algorithms contribute to the animation of virtual creatures. This includes our work on motion capture from video (Section  6.2.6 ); the physically-based animation tools (Sections  6.2.1 and  6.2.2 ).

A first work towards the perceptive evaluation of animation has been achieved in collaboration with the Department of Psychology of the U. of Geneva for facial animation. A study has been made to evaluate what different parts of the brain are activated when a picture of an expressive face is showed to a subject, with gaze pointing towards the subject or not. It has been necessary to adapt a 3D model to standard photographs of expressive faces, so that the eye orientation on the photographs could be accurately controlled in a realistic manner.
