摘要I摘要近年来，随着网络技术的飞速发展与普及，商品展示设计进入了全新的电子商务领域。目前大多数电子商务系统中对产品的展示都是基于二维的单方面平面展示，不能全面展示商品如结构、功能等方面的内在信息，用户只能从视觉上来感受，缺乏三维的实时交互功能，这无疑是影响网上产品展示效果的因素之一。以三维的虚拟空间和实时交互为特征的虚拟现实技术在这方面得天独厚的优越性以及它与Internet技术的无缝结合，可以提供更逼真的、具有交互性的三维可视化环境，从而实现消费者与产品之间的零距离接触。为了实现商品的三维实时交互展示，使浏览者具有身临其境的感受，课题对基于网络的交互式产品虚拟展示技术进行了深入研究。本文在研究目前商品展示现状的基础上，分析了传统展示与虚拟展示的优势和劣势，将传统展示设计理念与电子商务相结合，提出了基于Virtools平台下的交互式产品虚拟展示方法，并以减速器为例阐述了产品交互式虚拟展示设计的制作流程以及各个环节的实现方法。该平台为企业用户提供了交互设计的功能，为顾客用户提供了交互展示的功能，并对构建这样一个交互式虚拟产品展示系统开发平台所需要的关键技术进行研究，其中包括对产品组件信息的管理、交互操作功能的设计、交互式虚拟拆装、减速器运动仿真和个性化定制等功能的设计，然后对这些功能在Virtools平台上的具体应用实现进行了详细的介绍。最终利用计算机网络、虚拟现实、人机交互、网络数据库等技术建立一个基于网络的应用于B2C电子商务的虚拟展示系统，营造一种新型的产品展示方式。该系统弥补了传统商业展示受时间空间限制、交互性差等缺点，对缩短产品设计周期，降低产品寿命周期成本，提高产品质量有着显著的意义。关键词:虚拟展示；交互式；三维可视化；Virtools江苏科技大学工学硕士学位论文IIAbstractIIIAbstractInrecentyears,withtherapiddevelopmentandpopularizationofnetworktechnology,thedesignofproductexhibitionhasenteredanewareaofelectroniccommerce(E-commerce).Atpresent,mostvirtualexhibitionisbasedontwo-dimensionalinE-Commercesystems,whichcannotfullyshowcommoditysuchasstructure,function,andsotheintrinsicinformation,theuserscantouchthecommodityonlyfromthevisualexperience,lackofthree-dimensionalreal-timeinteractivefunction,whichisthefactorsaffecttheeffectivenessofonlineproductsundoubtedly.Withtheadvantagesofthree-dimensionalvirtualspaceandreal-timeinteractive,aswellasitsseamlessintegrationwiththeInternettechnology,makestheintroductionofvirtualrealitytechnologyintoE-commercecanprovideamorerealistic,withinteractive3Dvisualizationenvironment,forachievingzerodistancebetweencontactsandproducts.Inordertoachievereal-timeinteractivethree-dimensionalproductexhibition,sothattheviewerhastheimmersiveexperience,thesubjectdeeplystudiedtheinteractivevirtualexhibitionbasedonweb.ThisarticleanalyzedtheadvantageandshortcomingofVirtualReality，withthecombinationoftraditionaldesignideaswithE-Commerce,andputforwardamethodofinteractiveproductexhibition,thensetreducerforexampletoillustratehowthevirtualexhibitionofproductdesign,aswellasallaspectsoftheproductionprocessareimplemented.Thisplatformofferedinteractivedesignfunctionfortheenterpriseusersandinteractiveexhibitionfunctionforthecustomers,andresearchedkeytechnologiesofconstructinginteractivevirtualproductexhibitionsystem,includingthemanagementofcomponentinformation,thedesignationofinteractivefunction,theinteractiveVirtualAssembly,thesimulationofreducerrunningandpersonalcustomizationfunction.ThenmakepracticalapplicationontheVirtoolsplatform.Finallyestablishedthevirtualexhibitionsystemwhichbasedonwebbyusingthetechnologyofcomputernetworks,virtualreality,human-computerinteraction,databasetechnologythatcanapplyinB2Csystem,creatinganewtypeofproductexhibitionmode.Thissystemismadeupfortime-spaceconstraints,poorinteractionshortcomings.Thesystemhasasignificantmeaningonshorteningproductdesigncycles,reducingproductlifeandcyclecosts,improvingthequalityofproducts.Keywords:virtualdisplay;interactive;three-dimensionalvisualization;Virtools江苏科技大学工学硕士学位论文IV目录V目录摘要......................................................................................................................................IAbstract..................................................................................................................................III第1章绪论...........................................................................................................................11.1课题研究背景..........................................................................................................11.2虚拟现实技术概述..................................................................................................11.2.1虚拟现实技术特征.........................................................................................21.2.2虚拟现实技术的分类.....................................................................................21.2.3虚拟现实技术应用.........................................................................................31.3虚拟展示技术的国内外研究现状..........................................................................61.3.1国外研究现状.................................................................................................61.3.2国内研究现状.................................................................................................71.3.3现有系统存在的问题.....................................................................................81.4论文研究内容及体系结构......................................................................................81.4.1研究内容.........................................................................................................81.4.2体系结构.........................................................................................................9第2章虚拟展示系统技术研究..........................................................................................102.1主流虚拟现实技术比较和选择.............................................................................102.1.1主流虚拟现实技术介绍................................................................................102.1.2主流虚拟现实技术的选择................................
