Les séminaires de l'UR sont des séminaires scientifiques, dont la vocation est d'être la vitrine scientifique de l'UR. Ils doivent impérativement concerner tous les personnels chercheurs de l'UR et pas seulement un seul projet de recherche. Les séminaires ont lieu dans le grand amphi de l'INRIA, a priori une fois par mois. Pour proposer un séminaire, envoyez un courriel à l'animateur.
Jeudi 04 novembre 2004 à 14h00 dans le grand amphi : Leveraging GPUs for Advanced Visualization, par Chuck Hansen (University of Utah & INRIA).
In recent years, scalable architectures and algorithms have led to unprecedented growth in computational data. The effectiveness of using such advanced hardware that produces large amounts of high-resolution data will hinge upon the ability of human experts to interact with their data and extract useful information. Many visualization techniques use the old, but efficient, method of Phong shading for both surface rendering and direct volume rendering. Many of these applications could benefit from more sophisticated shading models that capture subtle light effects and characteristics. This coupling of advanced computer graphics and visualization methods has the potential to produce better insight than previous methods. In this talk, I will present an overview of such advances: the use of multidimensional transfer functions and the incorporation of advanced shading techniques.
Charles (Chuck) Hansen is an associate professor of computer science in the School of Computing and an associate director of the Scientific Computing and Imaging Institute at the University of Utah. He received a BS in computer science from Memphis State University in 1981 and a PhD in computer science from the University of Utah in 1987. From 1997 to 1999, he was a research associate professor in CS at Utah. From 1989 to 1997, he was a Technical Staff Member in the Advanced Computing Laboratory (ACL) located at Los Alamos National Laboratory, where he formed and directed the visualization efforts in the ACL. He was a Bourse de Chateaubriand PostDoc Fellow at INRIA, Rocquencourt France, in 1987 and 1988. His research has made contributions to the fields of scientific visualization, computer graphics, parallel computation and computer vision.
