隨著虛擬現實技術、網絡技術的發展，基于網絡的虛擬系統開發和研究成為研究的熱點，己經受到商家越來越多的關注。虛擬汽車展示系統應用于汽車展示，銷售中具有“節省大量經費”、“突破了時間和空間的局限”、“避免選車者選購的麻煩”等優點。目前的虛擬汽車展示系統的真實感、交互性和效果等方面與現實需要相差甚遠，不能滿足商家和消費者的需求，而Web3D技術的產生使這些問題得到了解決。Web 3D是一種新興的網絡三維技術，利用這種技術制作出的網絡虛擬汽車展示系統具有良好的交互性和沉浸感，所以已經被越來越多的商家和消費者所關注。本論文著眼于Web 3D技術在汽車展示系統中的應用。首先介紹了與Web 3D技術緊密相關的虛擬現實技術，包括其基本概念和分類。而后探討了虛擬展示系統的相關內容，包括概念、類型及應用于實踐的理論依據。然后介紹了幾種Web 3D技術，并比較各自的特點，總結了用Web 3D技術開發網絡虛擬展示系統的大眾化方式：即將虛擬對象的建模與交互的設計分開進行，先在專業的建模軟件中構建三維模型，再導出到專門的交互軟件（如Cult 3D Designer）中設置交互。并以《汽車展示系統》開發為例，介紹了利用Web 3D技術開發汽車展示系統的流程

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
