采用VRML虚拟现实技术构建的公路运输勤务虚拟场景，本身不具有通信功能。该文扩展了VRML的scr ipt节点的功能，能够支持网络通信，使得公路运输勤务虚拟场景能够通过网络接收数据并能实时进行场景的重建。应用实例说明了该方案的可行性。-VRML virtual reality technology used to build the road transport logistical virtual scene itself does not have communication capabilities. This paper extends the VRML' s scr ipt node' s function, to support network communications, making road transport, logistical support virtual scene through the network and can receive data in real-time reconstruction of the scene. Application examples illustrate the feasibility of the program.
