Grants supporting the CYBER research project
The CYBER-I project was supported by the ``ACI Jeunes Chercheurs'' of the Department of the Research (2001-2003). The continuation of this project is CYBER-II which is supported by the ``Massive Data'' program of the Ministry of the Research (2003-2006). In this second step, we will improve the realism by augmenting the number of cameras (approximatively 20), by using a grid of PC and by visualizing the augmented scenes at very high resolutions, using a multi-projector setup.
Research Ministry grant: SHOW
SHOW is a collaborative research action funded under the French Ministry of Research ``Massive Data'' program, a program for projects for processing, managing and visualizing very large datasets.
SHOW joins together four INRIA projects: Reves of INRIA Sophia, ISA of LORIA and Iparla of UR-Futurs (in Bordeaux). We are working on very large datasets, and we extract their structure for edition and interactive display.
The ARTIS project is working on very large datasets that represent an architectural model, including walls, windows, doors, furnitures, and small objects. The model is unstructured, as often happens in industrial applications, usually as the consequence of applying an automatic translator on the 3D data.
We are working on the automatic generation of a spatial and semantic structure out of this unstructured dataset, using geometrical tools and techniques from Computer Vision. The goal is to separate and identify in the database the walls, furniture and other objects. The other research projects will be using the generated structure for simulation, parameterization and visualization of the architectural dataset.
Region Rhône-Alpes investigation grant: DEREVE
The Region Rhone-Alpes is funding the Dereve research project. The project has been going on for three years in its first phase (Dereve, 1999-2002) and is now in its second phase (Dereve II, 2003-2006). The Dereve research project is grouping together the ARTIS and EVASION research teams of the GRAVIR research laboratory, the LIRIS research laboratory in Lyon and the ICA research laboratory in Grenoble. The goals of the Dereve project are to render large and animated virtual environments in real time, using either photorealistic rendering or non-photorealistic rendering.
In the Dereve project, we are also working in collaboration with the ARIA research laboratory of the Lyon school of Architecture, who is producing a 3D model of the ``Ideal City'' by the famous Lyon architect, Tony Garnier. Since the city was never built, the architects are seeing fit to have a non-photorealistic rendering of the city, to underline its virtual status.
INRIA investigation grant: MIRO
ARTIS is participating to the ARC MIRO in collaboration with IPARLA (INRIA Futurs) and associate partners: Roberto Scopigno (Istituto CNUCE, Pisa, Italia), Robert Vergnieux (AUSONIA, Institut de recherche sur l'antiquité et le moyen Age, Bordeaux), Bernard N'kaoua (Cognitive Science Group, Bordeaux 2) and Digisens SA (Annecy, France).
In this project, we are interested in using NPR for the interactive and legible rendering of complex 3D scenes. The complexity is related to the massive amount of data and to the intrinsic nature of information (images, texts, illustrations...). Many examples in scientific visualization prove that photorealism does not always offer meaningful images. For example in medical books, the representation of organs is more frequently based on sketches and annotations than on photographs.
State of the art rendering techniques do not offer suited tools for perceptually effective, legible rendering of complex data. Researchers in the ARTIS and IPARLA projects are working on these topics, in the context of archeology, museography, medical simulation, all applications that require specialized visualizations. To address the legibility question we rely (i) on the skills and experience of the IPARLA and ARTIS teams; (ii) on the knowledge of specific users: archeologists, museum curators, industrial users at Digisens (the startup specialized in CTscan reconstruction and dental chirurgy); (iii) on the skills of the Bordeaux lab of cognitive psychology who helps us to define the type of validation needed for our methods.
INRIA investigation grant: GEOREP
ARTIS is participating to the ARC GEOREP. Following his work on heightfield rendering, Lionel Baboud is working with Bruno Levy to replace complex geometric objects with small geometric patches encoded as heightfield textures.
