Virtual Community Based On The Vrml Multi-user Environment And Constructed

Virtual community is an open, distributed and integrated communicating environment. It concerns many domains of computer application technology such as virtual reality, multimedia, network communication CSCW etc. VRML is a criterion describing virtual environment scene. This thesis researches VRML and its programming characters, creates architecture of VRML multi-user environment. Then we realize 3D chat room based on VRML multi-user environment and research some aspects including virtual environment creation, communication between VRML virtual reality and exterior environment, avatar in VRML multi-user environment, interaction and awareness, share behavior, integration of VRML multi-user interface and 2D multi-user interface, audio video communication technology, creation communication protocol and datagram adapted to VRML multi-user environment, creation CSCW architecture, creation of avoidance conflict-avoid mechanism and safety mechanism, realizing method of network communication etc. At last, it makes some prospects of the developing of this system.
