Abstract : Users of distributed virtual reality applications interact with users located across the network. Similarly, distributed object visualization systems store dynamic data at one host and render it in real-time at other hosts. Because data in both systems is animated and exhibits unpredictable behavior, providing up-to-date information about remote objects is expensive. Remote hosts must instead apply extrapolation between successive update packets to render the object's true animated behavior. This paper describes and analyzes a position history-based protocol in which hosts apply several recent position updates to track the position of remote objects. The history-based approach offers smooth, accurate visualizations of remote objects while providing a scalable solution.
