Keywords : High fidelity rendering, real-time,

Topics of the collaboration: The targetted objective is real time rendering and real-time golbal illumination computation for static and dynamic scenes. The first objective is real-time high fidelity rendering of dynamic scenes. Rendering complex scenes using a classical graphics pipeline (Z-buffering, Phong's shading model, multitexturing, etc.) can be efficiently performed with commodity graphics cards. However, real-time rendering of scenes, for which global illumination is computed, still is a challenge for many researchers. Indeed, global illumination followed by a rendering step (that we call high fidelity rendering) is a demanding process in terms of computing and memory resources. The approch proposed in this collaboration has to intensively exploit the performances of the new graphics cards to meet the real-time constraint. The second objective (which has not been tackled yet in this collaboation) is augmented reality. We aim at combining in real time synthetic and real images. To this end, we propose to: calibrate the real images, extract the light sources which lighted the real scenes, insert synthetic objects in the real scene for which we dispose only of their images captured by a camera, and finally light these synthetic objects with the extracted real light sources. The result will help a user, supplied with a head mounted display, to see a real scene augmented with synthetic objects lit homogeneously. |
1. Presentation of the foreign coordinator
Sumant Pattanaik is an associate professor at the School
of Computer Science, University
of Central Florida ,
Orlando. He has been Research Associate at the Cornell Program of Computer
Graphics, Cornell University
(1995-2001), got an INRIA postdoctoral position to join the SIAMES
project at IRISA/INRIA
Rennes (1993-1995) and was Senior Staff Scientist at the Graphics
Department of
NCST, Bombay (1985-1995).
He got his PhD in the Department
of Computer Science and Information Science of BITS, Pilani in
November 1993.
2. History of the collaboration

To my knowledge, there is no other collaborations between INRIA and the
University of Central Florida.
3. Impact :
Yes, with Professor Charles Hughes from the UCF
.
He is involved in virtual and augmented reality. I have invited him for
two weeks in our group.
4. Miscellaneous : toute autre information que vous jugerez utile d'ajouter.
This year has been very rich in
terms of publications: 3 journal papers, one has already appeared in the IEEE
TVCG journal and
another (accepted) will appear in the IEEE CG&A journal before the end of this year. The third paper has just been accepted for publication in the IEEE CG&A journal
|
In 2007 we have addressed the following topics : (1) real-time rendering of complex natural scenes with dynamic lighting and shadow casting, (2) Real-time rendering of globally illuminated natural scenes lit by the sun and the sky.
