本文讨论将视频显示整合到虚拟环境中的方法。它侧重于由分布式多用户模拟器创建的虚拟世界。静止图像或视频流代表这些三维世界中的空间。本文介绍了化身进入和离开视频区域的处理技术。在媒体融合技术中,当一个对象从一个区域移动到另一个区域时,用于表示该对象的媒体相应地发生变化。在第二种技术-对象跟踪中,当对象从一个区域移动到另一个区域时,其在第二区域中的动作由第一区域中的跟踪对象来表示。金字塔面板提供了一种处理视点变化的方法,因此二维图像和视频剪辑可以成功地模拟三维空间。论文最后提出了扩展我们的技术的方法,并列出了未来可能的研究。Cr
This paper discusses ways to incorporate video displays into virtual environments. It focuses on the virtual worlds created by a distributed multi-user simulator. Still images or video streams represent spaces within these three-dimensional worlds. The paper introduces techniques to deal with avatar movement into and out of video regions. In one technique—media melding—when an object moves from one region to another, the media used to represent that object correspondingly change. In a second technique—object tracing—when an object moves from one region to another, its actions in the second region are represented by a trace object in the first region. Pyramidic panels provide a means of dealing with viewpoint changes so that two-dimensional images and video clips can successfully simulate threedimensional spaces. The paper concludes by suggesting ways to extend our techniques and by listing possible future studies. CR
