The Medmesh color involves the teams Geometrica, Asclépios, Caiman and Odyssée from INRIA Sophia Antipolis and the Neurophysiology and Neuropsychology Laboratory of the hospital La Timone in Marseille. The goal is to test the mesh generator developped in Geometrica on real meshing problems provided by the other teams of the Color. See for examples figure 4 .

Figure 4. A mesh of a head generated from a few 3D images. The head volume is structured by four surfaces: the skin, the skull, the brain and the ventricule. Each region is meshed with a density related to the wavelength of electromagnetic waves in the correspondant material.


Participants : Pierre Alliez, Luca Castelli Aleardi, Olivier Devillers, Abdelkrim Mebarki.

We are a member of Geocomp an initiative from the national «Action Concertée Incitative Masses de Données». The project involves

— the «Laboratoire d'Informatique de l'Ecole Polytechnique (LIX), CNRS, Ecole Polytechnique»,

— the «Laboratoire Bordelais de Recherche en Informatique (LaBRI), CNRS, Université Bordeaux I»,

— the «Service de Physique Théorique, CEA Saclay» and the Geometrica team.

The project investigates compression schemes and compact data structures devoted specifically to geometrical objects.

INRIA Cooperative Research Initiative (ARC) Arcadia

Participants : Sylvain Pion, Daniel Russel, Monique Teillaud, Elias Tsigaridas.

The main objective of this ARC is to contribute to the unfolding of a geometric computing dedicated to quadrics having solid mathematical foundations and to validate theoretical advances by robust and efficient implementations.

Arcadia is a collaboration between Geometrica and Vegas at INRIA Lorraine. A foreign group is also involved, from the National University of Athens.
