| The VR technology(Virtual Reality,VR for short)which emerged in 1990s,is a new type of comprehensive information technology.It can bring about a virtual environment throughout computer technology.This type of environment could be perceived by human through the sense of sight,audition and touch.Userscould directly observe the environment,and interact with the environment.It could offer a realistic feeling.During 20 years’exploration and research,VR technology has been put in use in many fields,like virtual reality drive exercise for aircraft,ship and vehicle,virtual reality architecture,virtual reality game,virtual reality film art etc.Along with the development of computer technology, it is possible to carry out VR on PC.Put VR technology in Electrical Equipment of Hydroelectric Power Station, It can provide a 3D visual environment which is interactive, and so, the Electrical Equipment of Hydroelectric Power Station could be displayed much well, and users could have more convenient way to observe and evaluate.VR technology are analyzed and summarized in this paper.The basic structure of virtual Electrical Equipment of Hydroelectric Power Station display system is analyzed.The characteristic of virtual Electrical Equipment of Hydroelectric Power Station display system is summarized .Virtual Electrical Equipment of Hydroelectric Power Station display system is compared to the traditional method of product display,both the merits and defects are summarized.A relevant design flaw of virtual Electrical Equipment of Hydroelectric Power Station system is established.The main research work and the relevant achievement are as follow:First of all,this article introduces the Electrical Equipment of Hydroelectric Power Station,analyzes the virtual application in native and foreign country,common implementation technology,compares four technologies:JAVA3D, CULT3D, QuickTime and VRML.At last we choose VRML,Java and the background database method of combining to design the system.This method can give us more interaction, more immersion, more imagination, and it is more suitable to transfer on Web.Considering the requirement and the characteristics of VRML, this thesis gives technology route of implementation, expatiates the main research contents: geometry modeling,texture research,environment tlight,change viewpoint,apperceive action, switch sculpt.All these confirm the technology of the research and the implementation of the system.Then the thesis analyzes the work principles and basic characteristic of VRML,expatiates work pattern of VRML and conception pattern of VRML browser in detail.In the meanwhile the thesis discusses the key technology,besides it,the thesis mainly analyses three sides of the VRML explorer,the concept of the panorama,the route and event system,the light technology of VRML.After all,the thesis summarizes the syntax characteristics and function characteristics of VRML and Java Extensions,it gives the academic base of the development of the system.This paper is the use of computer virtual reality technology to achieve electrical equipment of Xinjiang tagake hydropower station virtual modeling, interactive and browser. The thesis analysis research content first,base on it,give the whole design of the system,and introduces the structure of virtual Electrical Equipment of Hydroelectric Power Station.The thesis gives the structure design paragraph of every parts,and introduces the develop tools simply.Besides, this thesis has given the method how to reduce romance of the system VRML file and optimize VRML file.At last, the work of the dissertation is summarized and the future research is put forward.The thesis has been offered the conclusion of this text at last, and the research direction that maybe continued in the future. |
