Virtual reality simulation mechanism on WWW

This paper addresses a fundamental, easy but powerful mechanism of Virtual Reality Simulation system on World Wide Web. The basic idea is to use Virtual Reality Modeling Language (VRML) to build the virtual world, and design a specific simulator to complete the common simulation work and drive the VR animation. According to the achievable mathematics and animation function, two types of this VR Simulation system are founded. The first one is to use VRMLScript or JavaScript to code the specific simulator. This mechanism really can be realized, however, the mathematical operations and the simulation model scale are limited. The other is to apply Java for coding the simulator, then use HTML to combine the VR scene and the simulator in the same WebPage, which can harmonize the VR animation running according to the simulation logic. Because Java is fully mathematics functioned and the Java code modules are entirely reusable, this VR simulation system, which is mainly recommended, can be easily realized on desktop PC and meet the basic interactive requirements of VR Technology without any extra hardware. A VR M/M/1/k Queuing simulation system is given to explain the mechanism. Finally, the overall Integrated Development Environment for this VR simulation system is also discussed.
