A Study On The Generation Method Of Virtual Reality Three-dimensional Scene Based On Java3D

With the rapid development of information technology and network technique, Three-dimensional virtual reality of human communication technology into new areas. Virtual reality is by a computer system create a people were there, can be obtained and the environment of the interactive experience of the virtual world. Highly comprehensive, electronic computers, communications, artificial intelligence and computer sciences, math, heat,, the mechanics and acoustic, mechanics, optics and physiology, science, also with aesthetic psychology and sociology, waiting for the social sciences. It is the development of productive forces and economic development huge and more modern science and technology development in the height of the application domains and reflect. In modern society, virtual reality more and more extensive scope of application. Through a virtual reality technical applications and users can create a favourable environment for interactivity man-machine, the user can enter the environment and can be comprehensive in real-time the scene. Especially in a network, the rapid development of e-business in the field of a three-dimensional has a vital role, tradition, two images, animation, unable to satisfy our customers in the real shopping experience in the cultivated that all perspectives, touch or fitting, "feeling". That is why the virtual reality technology applications will significantly enhance the feasibility of electronic commerce. In addition, in scientific research, construction, education and other areas of high quality and three-dimensional images of becoming more and more extensive, more and more people will benefit, they can more easily to the relevant work, more easily with other people in the relevant communication.。The subject's task was rapidly three dimensions can generate the scene graph and to put it down, the user can once again on the scene graph, and any alterations.In the preface of the thesis introduced the background of the discussion.Based the development and application of virtual reality,benetrated the benefit of 3D virtual reality to people living and science studing. Secondly, combine evolution of the VRML technology,descussed the developing state and problem which exist of three dimension technology.Because the VRML has no capability to access to native operating system and read or write files,at the end of the thesis,bring forward the solution of the problem.In the second part of the thesis,where discussed the technologis which related the question for discussion problem task,including Java,Java3D, Object-Oriented Programming, Object serialized file format and so on.The collectivity designing of the thesis is located in the third part, in this section further systematic expatiated on the subject of the design framework and implement programme and on the subject of solutions. Paper is the fourth part of the detailed design, the panel and its class in two ways to introduce the project design. The fifth part is running, the overall interfaces, three view, the scene graph, menus function on four aspects in detail the programs are running after a result. so, reach conclusions. part six.The core thinking of of the thesis is that use Three Viewer used in engineering cartography to build 3D Scene Chart and user Object-Oriented method to sculpt three dimension object.finally,save the scene chart as Object serialized file format.After lying out the solution of the key technology of the discussion,the forth part or the thesis is particular design.Include class design,arithmetic realize and so on.
