Design And Implementation Of Virtual Campus Roaming System Of Pingtan Occupation Technical Secondary School

Accompanied by the rapid development of computer network technology, network technology has become an important research direction in all subjects, but how can virtual reality(Virtual Reality, VR) technology on the WEB has become the technology one of the important branch.Virtual Reality Modeling Language(Virtual Reality Modeling Language, VRML) is a description interactive 3D objects, as well as the file format of the objective world, is mainly used for Internet, intranet, and local client systems, but also the combination of the three-dimensional graphics and multimedia universal conversion format. VRML language broad range of applications, including all aspects of engineering, scientific visualization, multimedia presentations, entertainment, education, Web pages, and shared virtual world.This system is mainly based virtual campus roaming interactive systems in the VRML scene modeling, interactive, and roaming technology, comprehensive analysis of the modeling language to build a virtual scene of VRML. Made in this article are as follows:1. the use of the technology of virtual reality technology as well as VRML and JavaScript scripts, determined based on the VRML browser plug-in technology solutions, refine the method attribute level to build complex scenes;2. the prototype of the system requirements analysis and system functional design, adopt coding stage depending on the circumstances, the modeling of the campus buildings using three-dimensional tools and VRML combination of VRML and JavaScript combination of technical means for development of tools; way, then the model integration and optimization; playground, trees, mailboxes, fire hydrants and car model in order to add realism in the virtual campus.3. four functional modules based on the VRML virtual campus roaming system: Import map and enjoy the campus, roaming the campus and help modules for modeling and rendering; achieve VRML sensor, interpolator, and JavaScript and other technologies in the scene. entity to control the behavior.4. the use of black box testing and white box test VRML-based virtual campus roaming system, the final system evaluation...
