BIB-VERSION:: CS-TR-v2.0 ID:: STAN//CS-TR-94-1505 ENTRY:: March 04, 1994 ORGANIZATION:: Stanford University, Department of Computer Science TITLE:: Using a Position History-Based Protocol for Distributed Object Visualization TYPE:: Technical Report AUTHOR:: Singhal, Sandeep K. AUTHOR:: Cheriton, David R. DATE:: February 1994 PAGES:: 26 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. NOTES:: [Adminitrivia V1/Prg/19940304] END:: STAN//CS-TR-94-1505
