Front-projection display environments suffer from a fundamental problem: users and other objects in the environment can easily and inadvertently block projectors, creating shadows on the displayed image. We introduce a technique that detects and corrects transient shadows in a multi-projector display. Our approach is to minimize the difference between(More)
Front-projection displays are a cost-effective and increasingly popular method for large format visualization and immersive rendering of virtual models. New approaches to projector tiling, automatic calibration, and color balancing have made multiprojector display systems feasible without undue infrastructure changes and maintenance. As a result,(More)

Museum curators will gladly maneuver items to any position you ask, but visualization is always limited to the window. Such is the current state of digital libraries. Digital libraries house media of ever-increasing complexity, from models of statues to virtual(More)
