Research Based on the Communication of VRML Virtual Scenes and Java

The Virtual Reality Modeling Language (VRML) is a standard to describe virtual scenes.VRML 2.0 standard is highly focused on as published.As a matter of fact,most applications perform perfectly in the construction of static scenes and the use of its own events and routes,but what has not been paid enough attention to is further interactive functions on how to achieve required datas, and how to set explicit parameters.This paper researches the way that VRML and java combine and analyses their communication protocal,by which,we have realized how to get coordinates of prescribed points and information about appointed site,as well as how to control virtual scenes interactively. Based on the communication of VRML and java,we can establish an interactive 3D multimedia world in Internet,and we have constructed the virtual reality system of our university.
