Design and realization of the interactive virtual laboratory based on VRML

On the base of Solidworks and Virtual Reality Modeling Language (VRML) technologies, the virtual laboratory and experiment devices are built up, which simulate the realistic laboratory environment. Moreover, some interactive modes are analyzed and discussed to implement these virtual scenes. Three dimensional cruising, two dimensional navigation functions are achieved. In order to realize the system, the research focuses on designs of three dimensional scene modeling and interactive function. By analyzing VRML principle and its optimization technology, a real-time downloading method based on net management is presented to solve speed problem facing in a large scale virtual scene in a networked environment. The whole system has high trueness shows that the VRML technology is valuable in experimental education.
