Paper Abstract

In this paper we illustrate an application that displays high-resolution images on Multi-Projector Tiled High Resolution Display Wall. Our goal is to enable the users to view high-resolution image data, such as photos from satellites and microscopes. Panoramas can also be played circularly. Users pan across the image, scale the image, and play panoramas interactively. Our prototype is implemented over a local area network with a PC cluster and a monitor. Image data are initially stored in the monitor PC. The critical issues emphasized in this paper are: using dynamically-selected multi-resolution texture hierarchy to overcome the limit of texture size, using binary-tree transferring structure to reduce the latency from O(N) to O(log2 N)(N is the number of Displayer PCs), and using parallel Macro-Micro clocks for system synchronization to eliminate accumulated displacement while achieving a high frame-rate.
