【摘要】 Internet的迅猛发展给房地产业提出了新的要求和挑战。本文在对房地产行业销售管理制度现状分析的基础上提出了基于CRM策略的房地产销售，制作了逼真的虚拟现实场景，并在场景中加入了分形算法生成的三维分形树，最后将场景和动态网页数据库集成，构建了数据库查询功能和交互虚拟现实场景结合的系统。 第一章介绍了先进的信息和管理技术正逐步融入房地产业。首先分析了虚拟现实技术的概况、在国内外的发展现状及其在房地产中的应用；然后介绍了房地产CRM的概念，指出了电子商务模式下CRM的特点、CRM的运作流程和几大模块的内容，最后分析了房地产行业销售管理的现状和不足，阐述了本文研究的意义和内容。 第二章首先对几种流行的虚拟现实技术进行了介绍，并从中选择了VRML技术路线来建立虚拟场景。在需求分析后明确了虚拟场景要达到的效果，然后详细介绍了虚拟场景建模的三个主要流程：数据采集、3DSMAX形体建模、VRML文件导出并优化，分析了建模过程中遇到的问题，并讨论了一些方法和技巧。介绍了场景漫游的方法。最后介绍了全景漫游技术及制作过程。 第三章在可行性研究的基础上提出了基于CRM策略房地产销售的四个目标，即吸引客户、识别客户、网上购房、网上定制，并分别介绍了具体实现的方法和过程；例举了构建系统数据库时应考虑的几大因素，并根据功能要求建立了数据库，最后讨论了数据的完整性。 第四章阐述了植物形态结构分形模拟的主要方法，指出其中的难点；接着提出了基于VRML的递归分形算法；然后论述VRML和Java结合的途径和具体步骤，并通过递归分形算法生成了若干种具有交互性的三维分形植物的实例，应用到了虚拟场景中去。 第五章介绍了系统的体系结构及开发运行环境，进行了Web数据库的连接和VRML、Applet与ASP集成；接着分析了系统的整体框架，介绍了系统的登录和注册的页面，然后介绍了系统软件的六个功能模块，并给出了具体实现。 第六章对本文的工作进行总结，展望了本课题的今后研究方向。更多还原

【Abstract】 The rapid progress of Internet brings forward new demands and challenges to the industry of real estate. Based on the analysis of the current distribution and management system of the industry of real estate, the dissertation presents a new distribution method of real estate based on CRM strategy. Vivid virtual scene is built and 3D fractal trees made by fractal algorithm are joined to the virtual scene. At last the virtual scene is integrated with dynamic web database, and the system that combined with the function of database inquiry and interactive virtual scene is established.In chapter 1: The advanced information and management techniques are applying to the industry of real estate. The general situation and the development status of the technique of virtual reality are introduced. And the application in the industry of real estate is analyzed. Then the conception of real estate CRM is introduced. The operation mode and content of CRM in electric commerce are studied. Status in quo and deficiency of distribution management in the industry of real estate are analyzed. In the end the significance and content of this dissertation are illuminated.In chapter 2: After several prevalent virtual scene modeling techniques are contrasted, the technique of VRML is adopted. The effect that the virtual scene should achieve is confirmed after the requirement analysis. The three main flows of virtual scene modeling are discussed in detail and the problems met during the process of scene modeling are analyzed. Some techniques and skills are illuminated. And the method how to roam in the virtual scene is expatiated. In the end, the process of the technique of panorama is discussed.In chapter 3: On the base of feasibility study, the four objects of Real Estate Shopping System based on CRM strategy are brought out, that are attract client, distinguish from client, purchase house online and customize online. And the detailed function and process of the objects are introduced. Factors that should be taken into account when establishing the database are listed and the database is established according to the demands. At last, the integrality of the data is discussed.In chapter 4: The main methods of fractal simulation of the configuration of plants are analyzed and the difficulties in them are pointed out. Then a simplified algorithm of L-System based on VRML is put forward. The detailed methods by which VRML interact with Java arediscussed. By using the simplified algorithm of L-System, examples of interactive 3D fractal trees are generated and applied in the virtual scene.In chapter 5: The architecture and the environment of exploitation of the system are introduced. The web database is connected. VRML, Applet and ASP are integrated. The framework of the system is analyzed. The login and register pages are introduced. Six function modules of the system are introduced and realized.In chapter 6: The work of the dissertation is summarized and the future research is put forward.更多还原
