The Research Of Engineering Mechanics Practice Net Application Based On Virtual Reality

In the area of teaching, Virtual Reality(VR) as another new teaching mediacame after multi-media technology.This paper studies VR from its definition, its characteristics (multi-Sensation, Presence, Interactive, Autonomy), its basic composition and its classifications, The usages and research wok about VR all over the world are also researched. It points out that the applications of VR to Engineering Mechanics net teaching are full of feasibility and necessity. In order to acquire this aim, the experiment of Engineering Mechanics is virtual, 3DS MAX software is used to make models, which are saved as VRML type files next. Then these models are controlled by programs edited in VRML, and they are set interactive actions. The completed scene could solve the question that students in their own houses could not freely enter the "laboratory" to operate the experiment devices in the INTERNET world. This paper gives some PROTO node types about VRML too, which could be easily applied to Engineering Mechanics net teaching. So according to the CAI basic teaching theories and CAI design laws, Engineering Mechanics software is edited by three soft wares, which are Dreamweaver MX, Flash MX and Fireworks MX. The virtual experiment is embedded in the network, so what to have done is extensively beneficial to net teaching.
