分布式虚拟现实应用程序的用户与整个网络上的用户进行交互。同样,分布式对象可视化系统将动态数据存储在一个主机上,并在其他主机上实时渲染。由于两个系统中的数据都是动画的并且表现出无法预测的行为,因此提供有关远程对象的最新信息是昂贵的。相反,远程主机必须在连续的更新数据包之间应用外推,以呈现对象的真实动画行为。本文介绍并分析了``基于历史记录''协议,其中主机应用了一些最近的位置更新以跟踪远程对象的位置。基于历史记录的方法在提供可扩展的解决方案的同时,提供了远程对象的平滑,准确的可视化。
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.
