The construction of virtual space in experiment of machinery bases based on VRML

With the development of the network tutoring, the tutoring in experiment is becoming the important part of network tutoring and the building in experimental resources. In order to realize the network tutoring in experiment of machinery bases, it is necessary to simulate of experimental apparatus and dynamically simulate of the experiment process. Virtual Reality Modeling Language can create an interactive 3-D virtual world in Internet. In this paper, the technique of VRML and Java language in network tutoring in experiment of machinery bases is explored, and by using example, modeling in experimental apparatus of machinery bases courses and key technical issues in experiment dynamic simulation are also discussed. By using 3-D modeling software, for example, Pro/e and CAXA can create static models of experimental apparatus. By using the technique of VRML and Java language can realize experiment dynamic simulation. The realization of network tutoring in experiment of machinery bases exploits a new means of tutoring in experiment of machinery bases.
