摘　　要：分布式虚拟现实具有虚拟现实的交互特性和网络的分布特性,满足了异地用户协同工作的需求。由于受到网络带宽、时延以及异构性等因素的限制,分布式虚拟现实系统中的3D图形文件要求尽可能小并具有跨平台的特性。本文介绍了基于X3D的虚拟场景中用户和场景交互的原理、方法以及实现过程,并给出了一个典型的应用实例。Distributed Virtual Reality （DVR） has the distinct interactive characteristics of virtual reality and the distribution characteristics of network, so it meets the needs of the collaborative work for long-distance users Due to the constraints such as network bandwidth, delay and heterogeneity, DVR system demands that 3D graphic files should be as small as possible and have the characteristics of cross-platform. This paper introduces the principles, methods and realization process of interactive techniques between users and virtual scenes based on X3D, and provides a typical application example.
