摘   要
 
 隨著虛擬現(xiàn)實(shí)技術(shù)、網(wǎng)絡(luò)技術(shù)的發(fā)展，基于網(wǎng)絡(luò)的虛擬系統(tǒng)開(kāi)發(fā)和研究成為研究的熱點(diǎn)，己經(jīng)受到商家越來(lái)越多的關(guān)注。虛擬汽車展示系統(tǒng)應(yīng)用于汽車展示，銷售中具有“節(jié)省大量經(jīng)費(fèi)”、“突破了時(shí)間和空間的局限”、“避免選車者選購(gòu)的麻煩”等優(yōu)點(diǎn)。目前的虛擬汽車展示系統(tǒng)的真實(shí)感、交互性和效果等方面與現(xiàn)實(shí)需要相差甚遠(yuǎn)，不能滿足商家和消費(fèi)者的需求，而Web3D技術(shù)的產(chǎn)生使這些問(wèn)題得到了解決。Web 3D是一種新興的網(wǎng)絡(luò)三維技術(shù)，利用這種技術(shù)制作出的網(wǎng)絡(luò)虛擬汽車展示系統(tǒng)具有良好的交互性和沉浸感，所以已經(jīng)被越來(lái)越多的商家和消費(fèi)者所關(guān)注。本論文著眼于Web 3D技術(shù)在汽車展示系統(tǒng)中的應(yīng)用。首先介紹了與Web 3D技術(shù)緊密相關(guān)的虛擬現(xiàn)實(shí)技術(shù)，包括其基本概念和分類。而后探討了虛擬展示系統(tǒng)的相關(guān)內(nèi)容，包括概念、類型及應(yīng)用于實(shí)踐的理論依據(jù)。然后介紹了幾種Web 3D技術(shù)，并比較各自的特點(diǎn)，總結(jié)了用Web 3D技術(shù)開(kāi)發(fā)網(wǎng)絡(luò)虛擬展示系統(tǒng)的大眾化方式：即將虛擬對(duì)象的建模與交互的設(shè)計(jì)分開(kāi)進(jìn)行，先在專業(yè)的建模軟件中構(gòu)建三維模型，再導(dǎo)出到專門的交互軟件（如Cult 3D Designer）中設(shè)置交互。并以《汽車展示系統(tǒng)》開(kāi)發(fā)為例，介紹了利用Web 3D技術(shù)開(kāi)發(fā)汽車展示系統(tǒng)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
