随着虚拟现实技术、网络技术的发展，基于网络的虚拟系统开发和研究成为研究的热点，己经受到商家越来越多的关注。虚拟汽车展示系统应用于汽车展示，销售中具有“节省大量经费”、“突破了时间和空间的局限”、“避免选车者选购的麻烦”等优点。目前的虚拟汽车展示系统的真实感、交互性和效果等方面与现实需要相差甚远，不能满足商家和消费者的需求，而Web3D技术的产生使这些问题得到了解决。Web 3D是一种新兴的网络三维技术，利用这种技术制作出的网络虚拟汽车展示系统具有良好的交互性和沉浸感，所以已经被越来越多的商家和消费者所关注。本论文着眼于Web 3D技术在汽车展示系统中的应用。首先介绍了与Web 3D技术紧密相关的虚拟现实技术，包括其基本概念和分类。而后探讨了虚拟展示系统的相关内容，包括概念、类型及应用于实践的理论依据。然后介绍了几种Web 3D技术，并比较各自的特点，总结了用Web 3D技术开发网络虚拟展示系统的大众化方式：即将虚拟对象的建模与交互的设计分开进行，先在专业的建模软件中构建三维模型，再导出到专门的交互软件（如Cult 3D Designer）中设置交互。并以《汽车展示系统》开发为例，介绍了利用Web 3D技术开发汽车展示系统的流程

Car display system based on Web3D
ABSTRACT
With virtual reality technology, network technology, network-based virtual system development and research become the hot, businesses have been more and more attention. Virtual display system used in automotive vehicle display, sales have "substantial savings", "break through the limitations of time and space", "those who buy cars to avoid the trouble of the election," and so on. The current vehicle display system of virtual realism, interaction and effects with the real needs of very different and can not meet the needs of businesses and consumers, while the production of Web3D technologies so that these problems have been resolved. Web 3D is a new network of three-dimensional technology that uses this technology to produce a network of virtual car display system has a good sense of interactivity and immersion, it has been more and more businesses and consumers attention. This paper focuses on Web 3D technology in the automotive display system. First introduced with the Web 3D technology is closely related to virtual reality technology, including its basic concepts and classification. Then the virtual display system of the related content, including concept, types and apply the theoretical basis of practice. Then describes several Web 3D technology, and compare their characteristics, summarizes the technical development with the Web 3D virtual display system for popular way: about a virtual object modeling and interactive design separate from the first professional modeling software to construct three-dimensional model, then export to specialized interactive software (such as the Cult 3D Designer) set interaction. And to "Auto Show System" as an example, the use of Web 3D technology development process of automotive display system
