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 : Adrien Bernhardt, Marie-Paule Cani, Adeline Pihuit, Jamie Wither.

Several of the tools we are developing are devoted to a new generation of interactive modeling systems, following the general methodology based on sculpting and sketching metaphors described in the book  [25] :

We are currently working at ways to combine both techniques, in other to inspire from sketching for initial shape design, and from sculpting techniques for further deformation.

Synthesis of natural scenes

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

Many of the diverse fundamental tools we are developing (see Sections  6.3.3 , 6.3.6 , 6.3.7 ) 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 : Guillaume Bousquet, Marie-Paule Cani, Florent Falipou, François Faure, Sahar Hassan, Franck Hétroy, Lenka Jeřábková, 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 ), as well as Matthieu Nesme's Ph.D. (see Section  6.2.2 are being used in a new European medical project called Passport for Liver Surgery (see Section  8.1.1 ).
