The Research And Implementation Of Crane Simulation System Of Based On VRML

With the developing of Internet technology , graph technology and VR technology,application of computer is entering into a new phase.Network technology has been an important technology in computer field. Customers not only observe result of information dealed with from exterior but also want to take part in the environment of information dealed with in order to get real experience, which need information dealed with system set up on a information spaces of some dimensions, and VR technology flat is an mostly pivotal technology that supports information spaces of some dimensions.As a modeling language,VRML is regarded as the second generation of web language aiming at constructing interactive 3D multi-media on Internet.It can be used to describe attributes and behaviors of 3D objects,create virtual world, integrate texts, pictures, sounds, MPEG and so on. It can also be embedded with codes programmed by Java, JavaScript languages and makes the design of VR become more efficient.This paper has carried on the summary of Virtual Reality, VRML and the correlated technology. Based on comparing and analyzing the constructing model methods of Crane's Three Dimensional scene and proposes certain technical questions and methods in the modeling process for the synthesis and reasonable application of Solid Works , 3Dsmax and the editor VRML ,and then realizes Hoist Crane System based on PC machine.This paper compares all sorts of interactive way and utilizing several methods to realize its interactive function,Basing on VRML'S own interactive function and the Script node, with VBScript, JavaScript programming language and the Java language that has realized the scene interactive,and also designs each kind of module of operated control panel.Has studied the concrete realization methods of VRML and Java technology in the virtual scene and also realizes some parts of parameterized designs. Using Java language and VRML'S EAI programming connection, programmed with Java Applet that has realized the external controlfunction.Has studied virtual walkthrough technique, and has designed the corresponding modules. Has considering the questions of network transmission, and proposes the realization of the object geometry shape modeling methods with the use of the optimized code under the premise that does not affect the model precision, as well as how to optimizes and exaggerates the VRML documents, and has produced the concrete solutions.
