Optimized Representations for the Acceleration of Display- and Collision Queries

A rapidly growing computer graphics community has contributed to dramatic increase in complexity with respect to geometry as well as physical phenomena.

Abstract

A rapidly growing computer graphics community has contributed to dramatic increase in complexity with respect to geometry as well as physical phenomena. Simulating, approximating and visualizing geometry consisting of tens of millions of polygons simultaneously tested for collision or visibility is becoming increasingly common. Further, recent technological innovations from graphics card vendors have given impetus to achieving these results at very high frame rates. Despite tremendous developments in graphics hardware, capturing the complete surrounding environment poses a significant challenge. Given the added time constraint for real-time or interactive rates, simplified representations and suitable approximationsof physical effects are of key importance. This talk will focus on simplified representations and computations to achieve real-time performance for complex tasks and concentrates on a variety of topics including simplification, visibility, soft shadows and voxelization.

Biography

Elmar Eisemann studied mathematics at the University of Cologne and received his Vordiplom in 2001. The same year, he entered the École Normale Supérieure in Paris and completed the remainder of his education in France. He obtained a Licence/Maitrise/Magistere from Paris XI (2001-2003) and received a Master in Computer Science from the Grenoble Universities in 2004. He then prepared a PhD at INRIA Rhône-Alpes and obtained his doctoral degree in 2008. He collaborated with several international institutions and pursued a part of his studies abroad. He worked with Prof. Frédo Durand (6 months at MIT, 2003), Prof. John C. Hart (3 months at the University of Illinois, 2006), Prof. David Salesin (3 months at Adobe Systems Inc., Seattle, 2007) and Dr. Sylvain Paris (3 months at Adobe Systems Inc., Boston, 2008). Currently, Elmar Eisemann is the head of the newly-established research group ECLEXIS. He is a member of the Saarland University and the Max-Planck Institute for Informatics working as a senior researcher within the Cluster of Excellence on Multimodal Computing and Interaction (MMCI).
