Research of virtual reality in industrial design manufacture and performance testing

Virtual reality (VR) is a new method of visual operating and interacting of complex data can be realized by computers, in which one would have an immersed sense to observe and operate objects in three dimensions timely and unboundedly. VR is a new developing technique and a complex simulation tool for industry, it builds a simulated environment in which researchers can do many things such as driving, operating, designing and performance test in a unaffected way. Performance test plays an important role in vehicle design. Most of interactive processing in virtual vehicle manufacturing is perfect, but many deep interactive functions are under emphasis such as performance test after manufacturing, variation and recording of performance parameters. Research of VRML combining with JavaScript is presented in this paper, and vehicle designing and manufacturing, testing system are built based on it, in which we can real-time and dynamic control the car through keyboard and mouse, and get the real-time performance parameters.
