Discussion on Key Technologies of Virtual Reality Model of Network Teaching

With the development of virtual reality technology and popularization of school network, combining Java with the functions of VRML,a new method is found to design multimedia courseware for descriptive geometry and mechanical drawing.Technology of VRMLJava provided a new solution to problem of teaching model.In this paper research is conducted on how to make use of Java Applet through the EAI of VRML to realize the subtle interactive control of the node objects at virtual scene.Theory and realizing process is presented.At the same time, the key technology is discussed on how to make use of functions of VRML such as generating animation and realizing realtime mutual technology to realize of constructing virtual reality model of network teaching.
