The real-time display of huge geometry and imagery databases involves view-dependent approximations, typically through the use of precomputed hierarchies that are selectively refined at runtime. This talk focuses on the problem of terrain visualization, in which planetary databases involving billions of elevation and color values are displayed in PC graphics hardware at high frame rates. We show how innovative data structures, new out-of-core storage organization based on space-filling curves, and optimization using graphics processors can be used to solve this problem. New aerial surveillance methods produce massive video streams that must be displayed in real time. We discuss methods by which these massive video streams can be visualized.
