摘　　要： 网上商店其实就是一种商品信息的浏览,网上购物系统就是提供这种信息服务的“商场”。近年来,网络虚拟技术的发展为商家与客户进行信息交流开辟了一条新途径,特别是虚拟现实技术的发展,为网上最终实现网上虚拟商店的“真实化”提供了可能。 本文在广泛调研和查阅大量文献的基础上,总结了近年来国内外基于VRML//X3D的应用研究,分析了当前网上虚拟商店存在的主要不足以及今后的发展方向和趋势。提出建构基于VRML//X3D的网上三维虚拟商店系统,并以网上虚拟三维家具商店系统为例开发了原型系统。网上虚拟三维家具商店系统主要包括客户信息注册、家具信息搜索、三维店面、三维家具场景布置、购物车、后台管理和系统帮助等模块。三维家具商店系统的实现:采用3DS max6.0建构三维店面和商品模型,导出VRML//X3D场景文件;采用VRMLPad2.1编辑VRML//X3D文件,给场景添加贴图,利用VRML//X3D自身的交互功能节点实现系统的家具展示、家具材质变换、室内家具摆设、导航和利用Script节点编程实现三维店面菜单等交互功能;采用SOL Server2000作为服务器数据库系统;采用ASP技术实现三维店面与数据库的关联和实现三维店面家具的动态与交互更新。 论文展开了虚拟现实技术及其在电子商务应用的研究。研究主要是用VRML//X3D虚拟现实技术结合当前的网上购物系统技术平台,详细介绍了系统的设计架构,研究了VRML//X3D的造型、贴图、场景交互技术;探讨了VRML//X3D访问数据库技术。简述了实现场景环境、场景、商品模型的创建,视点切换,三维商品的主动展示、动态更新、交互更新以及数据库访问等关键技术,并给出了范例。 论文的创新点是:提出并实现VRML//X3D与数据库进行信息交换的机制、三维商品的动态更新和交互更新,使用户从注 The online store is actually one kind of merchandise' s information browsing, and the online shopping system is just 'the market' that provides this kind of information. In recent years, the development of the network virtual technology opens a new avenue for the information exchange between merchants and customers, especially the virtual reality technology development, as it provides the possibility to make the online virtual store 'to be real' .With the widespread investigation and study massive literature, this thesis summarized domestic and foreign the VRML//X3D applied research in recent years, and analyzed main shortcomings and the future developing direction and tendency of the current online virtual store. The thesis put forward a online 3D virtual store system based on the VRML//X3D, and has developed the prototype system, and the online virtual 3D furniture store system is taken as the example. The on-line virtual 3D furniture store system mainly includes customer's information registration, furniture information search, 3D shop, 3D furniture scene arrangement, shopping car, backstage management and system help module and so on. The realization of the 3D furniture store system: Used 3DS max6. 0 sofeware construct the 3D shop and the merchandise' s models, export the VRML//X3D scene documents;Used VRMLPad2.1 to edit the VRML//X3D documents, add texture to the scene' s models, realize the systems the furniture display, the furniture material switch, the indoor furniture display, navigation by the interactive functional nodes of VRML//X3D own and realize the 3D shop menu by Script node programming function and so on;Used SQL Server2000 as the database server system;Used the ASP technology realize the relationship between the 3D shop and database, and realize the active and interactive refreshing of the 3D shop' s furniture.This thesis made research on virtual reality technology and its application in the electronic commerce. The thesis ' researches are mainly on the VRML//X3D virtual reality tech
