Design and Implementation of Web-based Networked VE System

【Abstract】Virtual reality (VR) is a rapidly developing technology that has wide spectrum industrial and commercial applications. Networked virtual environments (VEs) are of growing interests to modern manufacturing industry; a dominating use of networked virtual manufacturing environments (VMEs) is on-line visualisation and collaborative control of 3D information. This has to be supported by real-time data transfer. To meet a broad range of common requirements for Internet-based VE communications, particularly for virtual manufacturing and collaborative design and control, this paper presents a networked virtual environment system that is designed to support networked virtual design and manufacturing. The system is implemented with the manufacturing message specification (MMS) standards so as to achieve a range of integrated manufacturing services into networked VEs over the Internet. 【Key words】Virtual reality(VR); Networked virtual environment; Virtual manufacturing device (VMD); Manufacturing message specification (MMS)
