Project-Team Presentation

GRAVIR joint project-team with CNRS, INPG and UJF.

The research at iMAGIS is driven by the simulation of complex phenomena in computer graphics. Users of virtual prototypes, such as scientists, engineers and architects, require interactive environments where they can create realistic models and run efficient simulations. Using current graphics systems, these competing requirements cannot be mutually satisfied. Therefore, our research focuses on finding acceptable compromises using innovative approaches. To this end we are both investigating fundamental problems and applying this new technology to practical systems. Fundamental issues include the development of efficient algorithms and the creation of geometric or physical models. Among our application domains are site evaluation, training simulators, medical simulation, scientific visualization, illumination simulation, urbanism, video games.

iMAGIS is a project of the INRIA and a member of the GRAVIR-IMAG laboratory, common project between the CNRS, the Institut National Polytechnique de Grenoble (INPG), the INRIA and the University Joseph Fourier (UJF).

Research themes

• Natural scene simulation (visualization of avalanches and of vegetation, simulation of bark, of brooks, of plant growing from photosynthesis...).
• Alternative representations (texture generation, volumic texture, hair models, animation textures, non photorealistic rendering...).
• Animation and modelization of deformable objects (models based on finite elements or on implicit surfaces techniques, collision detection and response, facial animation, surgery simulation...).
• Plateform for animation and virtual reality (TMR european project PAVR).
• Interactivity, augmented reality (manipulation and sharing of virtual objects, image-sound integration...).
• Complex environment visualization (scientific data, multiresolution techniques, complex scene representation...).
• Realistic rendering, illumination simulation (use of complex reflectance models, global illumination, hierarchical radiosity techniques, dynamic environments...).
• Algorithms for visibility, efficient data structures for complex scenes rendering (take into account of coherence, dynamic cases...).

International and industrial relations

• In the scope of the PRIAMM funding, we collaborate with the Infogrames society on the animation of an interactive vegetation for video games.
• As part of a " Thématiques Prioritaires 2000 " from the Rhône-Alpes region, we participate in a collaboration with the APACHE team (ID-IMAG laboratory) and the Yxendis society. The goal is the parallel physical simulation of textile on a PC cluster.
• The ARGOS project is a collaboration with the ERGA team (Grenoble University) and the french scholl of Athens. Its goal is the reconstitution and the interactive visualization of the greek city Argos from the geometric to the high-empire epoch.
• SIMULGEN is a european projet " Open Long Term Research " on radiosity simulation. The partners are the Girone University (Spain), the Max-Plank Institut fur Informatik at Saarbrucken (Germany) and LightWork Design (Great Britain).
• The Training and Mobility for Researchers european project PAVR Platform for Animation and Virtual Reality regroups eleven universitary teams (3 french, 2 swiss, 1 spanich, 2 british, 2 autrian and 1 belgium) which work in Computer Graphics and Animation. The goal is to identify and to solve the common problems that deal with virtual reality and animation.
