本文旨在介绍使用虚拟现实（VR）和视频技术相结合的概念，以便为视频会议提供共享环境，并解决一些重要但不同的问题，这些问题已经与这两种类型的系统确定。本文首先简要回顾了这两种技术。在此之后，提出了一个名为Vivid的原型系统，该系统将实时视频流分发和纹理化到多用户3d图形虚拟世界中的一般对象上（包括用户实施例的面部）。然后，本文讨论了如何通过视频连接和服务质量的空间控制来扩展该系统以支持更多的参与者。
This paper aims to introduce the concept of using a combination of virtual reality (VR) and video technologies in order to provide a shared environment for video conferencing and to address some important but different problems that have been pinpointed with both types of system. The paper begins by briefly reviewing these two technologies. Following this, a prototype system called Vivid is presented which performs the distribution and texturing of real time video streams onto general objects within a multi-user 3-D graphical virtual world (including onto the faces of user embodiments). The paper then discusses how this system will be extended to support larger numbers of participants through the spatial control of video connectivity and Quality of Service.
