Such data sets commonly result from computer simulations of complex physical phenomena (e.g., computational physics, climate modeling, ocean modeling) or from high-resolution imaging ( e.g., satellite imaging, medical imaging). The technology currently being used to represent massive data sets is inappropriate for interactive and efficient data analysis and visualization. It is impossible for a user of a visualization system to ``navigate'' through a data set consisting of several million (or billion) data points and analyze the data set entirely. In this talk, I will present various ideas that seem to be promising in the context of overcoming some of the problems associated with the visualization of very large data sets. I will point out the necessity to bring together ideas from approximation theory and geometric modeling (splines), computational geometry (tesselations), optimization (simulated annealing), and other related fields. I will point out avenues for representing massive data sets using hierarchical approaches that facilitate visualization and analysis. Bernd Hamann -- Biographical Sketch Bernd Hamann is an Associate Professor of Computer Science and Co-Director of the Center for Image Processing and Integrated Computing (CIPIC) at the University of California, Davis. From 1991 to 1995 he was a faculty member at the NSF Engineering Research Center for Computational Field Simulation, Mississippi State University, where he contributed to the development of computer-aided design (CAD), scientific visualization, and grid generation systems. His primary research interests are visualization, computer-aided geometric design (CAGD), and computer graphics. He is the author of over 50 refereed publications and has presented his research at leading conferences in the U.S. and in Europe. Hamann received a B.S. in computer science, a B.S. in mathematics, and an M.S. in computer science from the Technical University of Braunschweig, Germany. He received his Ph.D. in computer science from Arizona State University in 1991 (advisor: Gregory M. Nielson). Hamann received a 1992 Research Initiation Award and a 1996 CAREER Award, both awarded by the National Science Foundation. In 1995, he received a Hearin-Hess Distinguished Professorship in Engineering while working at the NSF Engineering Research Center for Computational Field Simulation. Please, take note of this coming event, and pass on the information to colleagues who may be interested. We are looking forward to seeing you at MERL.
