Research And Realization Of Collaboration Based On Virtual Reality

In the instrument and apparatus computer aided designing system, some collaborative systems still mainly based on the text and two-dimensional figure, misunderstand was happen in information interchange and can't change the sport parameter alternately, so there is greater limitation. The thesis named collaborative system based on VR and Web can overcome above-mentioned drawbacks, the quality of information interchange in the collaborative and distributed project has been improved greatly. The thesis analyzes at present about collaborative designing and virtual reality research results at first, on the basis of analyzing problem in collaborative design, the new solution is put forward. Through integrated JAVA3D with open standard and technology, such as JAVA, etc., collaborative design system based on WEB and virtual reality is researched and realized. In order to enable independently HUST-CAID (Harbin University of Science and Technology-Computer Aided Industry Design) System to support collaboration design, Analyzing to HUST-CAID system, provides an interface. Through interface that this thesis provides, we can easy to turn HUST-CAID system data structure into the data structure of JAVA3D. This interface offered very good foundation for collaborative designing under virtual reality. The thesis puts forward a new solution to collaborative design; regard WEB as a unified customer terminal; develop one server terminal which deal with message that customer sends. In the graphical collaborative display, what this system puts forward is a kind of new method expressing the information of models on the basis of XML, and adopts a kind of progressive display technology. Single resolution ratio net used in progressive display is more flexible compare with many resolution ratio nets. This solution don't need fussy pretreatment, can defining own display models based on the detail to which different users pay close attention. The framework obtains achievement through practice step by step in electrician instrument and apparatus system HUST-CAID that develops independently. HUST-CAID system is satisfied with extending to the network respect.
