Using a Position History-Based Protocol for Distributed Object Visualization,
Sandeep K. Singhal, David R. Cheriton · 1994
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. 1 Introduction In distributed object visualization systems, a host must accurately display dynamic data located at other hosts on a network. For example, each participant in a virtual reality environment moves about ...
