Research And Application On Web 3D Technology Based Java3D In The Of Data Visualization

Virtual reality technology is one of the hotest world's computer science research in the world. With the popularity of Internet applications and the influence continues to expand, the demand for the Internet, driven by commercial interests, from a variety of mature technologies related to birth of Web 3D. Web 3D is a web-based virtual reality interconnect technology for Web-three-dimensional graphics implementation. As an important representative of virtual reality technology that overcomes the shortcomings such as technology-based HTML pages to be limited to two-dimensional space, immersion is not strong.Web 3D is birthed with a good three-dimensional nature, flexible interaction and the simplicity of the hardware resource requirements etc which have been widely used.In this paper, Web 3D technology in data visualization applications for furniture using in-depth studies to illustrate the solution of making Web 3D visualization of knowledge and learning.We create an effective tool for the virtual context methods, and on this basis, the relevant system has some innovation nature of improvements. The main thesis is as follows:1) We hava an overview of the history of Web 3D technologies and research status. We summarized the Web 3D production process, Web 3D key technologies of the concept of virtual reality system, virtual reality systems and the analysis and comparison of the characteristics of the system architecture of the Web 3D in detail.2) We compare the main Web 3D visualization techniques in the world.Firstly, we hava a systematic comparison of the VRML/X3D, viewpoint, Cult3D, Java3 visualization technology such as the advantages and disadvantages. Then under the furniture data visualization background, we select Java3D technology as system structures.3) For the the need for roaming virtual reality scene,we described how to use Java3D and computer graphics used in combination, and its application to this system. Theoretically solved the roaming navigation, region of interest here, point of view three-dimensional smooth mobile browsing and other key technologies, you can select the region of interest here, free control of lighting, as well as choose a different material means the performance of three-dimensional model on display. It proved that the use of Java3D well make this system to achieve the desired objectives.4) We design and build a specific three-dimensional furniture e-commerce roaming system with the latest Web technologies closely on the market exclusively for the current show has opened up a two-dimensional e-commerce application. This system supports OpenGL and Direct3D in the bottom two versions. With a cross-platform and high-performance graphics rendering capabilities, the data terminal capable of supporting X3D, VRML, OBJ and other 3D file formats; and have the function of walking in, rotation, paning, regional amplification, switching point of view a variety of smooth interaction. We made the experiments on different platforms to test these different kinds of functions, thereby supporting the proposed in this paper that Java3D-based B / S structure, three-dimensional furniture, roaming the feasibility of virtual reality.5) In this paper, three-dimensional video-based furniture modeling adjacent frames were exploratory study. And we made some forecasts about Web 3D technology in data visualization in furniture, and the prospects for the future development of e-business prospects and.
