National projects

ANR Masse de données et simulation KAMELEON

Participants : Lionel Reveret, Laurent Favreau, Franck Hetroy, Marie-Paule Cani.

Current techniques for animating the skin surface of a virtual creature from the motion of its skeleton do not take into account complex phenomena such as the rolling of the internal tissue over the bones. In order to tackle this problem, a research project has been initiated between EVASION and the National Museum of Natural History in Paris. For the study of locomotion, the Museum has access to Xray video of live animals, making possible to visualize the motion of the internal skeleton during locomotion. Using standard stereovision techniques, the 3D surface of the animal will be extracted in order to be correlated into an innovative machine learning framework with the internal Xray data of the skeleton. As a result of this learning phase, more realistic 3D motion of the skin will be achieved, controlled by standard 3D skeleton motion. This project is sponsored by an ANR grant for the next three years. It gathers 4 participants: EVASION project, National Museum of Natural History, Université de Rennes et Université Paris 5.

ANR Masse de données et simulation NATSIM

Participants : Fabrice Neyret, Antoine Bouthors, Qizhi Yu, Marie-Paule Cani, Eric Bruneton, Jamie Wither, Cedric Manzoni.

This project aims at developping new techniques and hybrid representations to model, visualize, animate and transmit natural scenes. It involves EVASION, IRIT and LABRI. Evasion took action in two workpackages: edition tools in order to "sketch" high level user specification concerning the landscape, and animation of complex realtime scenes (such as rivers, clouds, trees).

ANR Chênes et roseaux

Participant : Lionel Reveret.

The aim of the project CHENE-ROSEAU is to develop and test experimental and theoretical methodologies for the analysis and simulation of the motion of plants induced by wind. The knowledge of motion of plants under wind is important for several reasons. First, in terms of plant damage, excessive motion can lead to lodging in crops, where the deformation becomes permanent or to wind throw in isolated or grouped trees. Second, motion of lesser amplitude is known to influence plant growth (thigmomorphogenesis), particle spreading, liquid retention on leaves or light spreading inside a canopy. More recently applications in computer graphics for video games or movies have appeared, where the simulation of realistic plant motion is still a major difficulty. Partners for this project are the Laboratoire d'Hydrodynamique-LadHyX (Ecole polytechnique), UMR 547 PIAF (Physiologie Intégrée de l'Arbre Fruitier et Forestier) (INRA), UR Ephyse (Ecologie fonctionnelle et Physique de l'Environnement) (INRA) and Projet EVASION (INRIA Rhône-Alpes).
