Initiative in Innovative Computing @ Harvard Seminar Series Wednesday, April 4, 2007; 4:00pm 60 Oxford Street, Room 330 Kai Li, Department of Computer Science, Princeton University Seminar Title: Princeton Scalable Display Wall Project Abstract In the last two decades, compute power, storage density, and network bandwidth have improved by more than three orders of magnitude. In the same time period, however, display resolution has merely doubled. The increased processor and storage capacities have enabled the computational sciences, but have simultaneously unleashed a data avalanche on the scientific community. As a result, scientific research is limited by data analysis and visualization capabilities. In order to improve visualization capabilities, we started Princeton Scalable Display Wall project in 1998 to investigate issues in building and using a large-format, scalable display system. Since then, we have built several display walls and software systems. Our latest display wall built in our lab uses 24 projectors to drive about 20 million pixels onto an 18’ by 8’ screen. The system uses an automatic alignment mechanism to achieve sub-pixel geometric alignment accuracy and is capable of running various 2D and 3D visualization applications. Our recent focus is to work with computational science researchers closely and help them use display walls in their data explorations. This talk gives an overview of the project, presents our current visualization activities, reports our lessons and experiences in building and using scalable display wall systems. ***Parking is available in the 52 Oxford Street Garage.
