Abstract
Recently, there has been a dramatically growth in the study of the Web technology. One of the most noticeable topics is the creation of virtual reality in the networked space (cyberspace). A standard called Virtual Reality Modeling Language (VRML) has been proposed. However, VRML 1.0 only defines the geometry part, it still needs a more comprehensive definition for the interaction behavior in the virtual world. In this thesis, we proposed a networked VR model which is composed of three main modules, namely, network module (for the network), virtual environment module (for visualization 3D virtual objects) and behavior module (for the interaction). Some basic functions of these modules are described. And relationship among them are also discussed. Furthermore, we implemented a networked chess game to demonstrate the feasibility of our proposed model. In our chess game example, all objects are 3D, and all changes of the scene caused by players' interactions are displayed to all interested participants. In other words, all participants share the same virtual world through computer networks.
