【摘要】：随着旅游成为大众化的必需品和日益平民化，旅游业成为了第三产业一个十分重要的支柱。旅游业对地区发展的带动性，对城市就业的拉动能力，对城市文化和名片的宣传效应也日渐凸显。作为信息密集型行业，基于虚拟现实技术的虚拟旅游不仅可以提升整个行业的信息化程度和行业的服务能力及资源的优化配置，还可以促进对自然、人文旅游资源的保护。由于Flash播放器在目前互联网用户中的使用率高达90%以上，因此，一个基于Flash3D的在线虚拟旅游系统，不仅不需要安装插件，而且可以整合目前最常用的多媒体元素，通过互动漫游设计，给游客提供更逼真的感受，实现用户体验质的飞跃。本文提出并实现了一个高效的、扩展性强的、可移植性高的在线虚拟旅游系统。系统基于消息机制，通过XML文件来实现各个模块和参数的集成和按需配置。通过对制约在线虚拟旅游系统的瓶颈分析，提出并设计了一个对三维场景构建过程的各个步骤都进行优化设计的方案，包括对模型文件、材质文件以及构建步骤的优化设计。针对目前虚拟旅游系统中表现方式单一的问题，本文实现了对各种多种媒体方式的支持，包括三维对象、Flash、视频、音频和图片等。通过本文的热点系统，不仅实现三维系统中对Flash的支持，通过热点的响应，还能对三维模型按需进行加载和展示，提高游客与景区的互动。通过对目前虚拟旅游系统漫游方式的研究，系统提出了一种新的互动漫游控制方法。利用WayPoint方法和最短路径寻路算法，实现了游客在场景中任意两点之间沿最短路径漫游，并通过一系列的漫游过程的优化设计，使漫游达到接近真实的漫游效果。系统基于用户体验的理论，结合系统的需求，实现了虚拟旅游系统中地图，，菜单等通用功能基于Flash的设计和实现。本文在综合考虑我国旅游业信息化基础上，对目前虚拟旅游系统的瓶颈进行分析，提出并实现了一个基于Flash3D的性能经过显著优化的在线虚拟旅游系统，为我国虚拟旅游的大规模应用的提供了借鉴。
[Abstract]:Tourism has become a very important pillar of the tertiary industry. Tourism plays an important role in regional development, urban employment, city culture and business card. As an information-intensive industry, virtual tourism based on virtual reality technology can not only enhance the information level of the whole industry, the industry's service capacity and the optimal allocation of resources, but also promote the protection of natural and humanistic tourism resources. Since the Flash player is currently used by more than 90% of Internet users, an online virtual travel system based on Flash3D not only does not need to install plug-ins, but also integrates the most commonly used multimedia elements. Through interactive roaming design, to provide visitors with more realistic feelings, to achieve a qualitative leap in user experience. This paper proposes and implements an online virtual tourism system with high efficiency, expansibility and portability. Based on message mechanism, the system realizes the integration and on-demand configuration of various modules and parameters through XML files. Through the bottleneck analysis of the online virtual tourism system, a scheme is proposed and designed to optimize the design of each step of the 3D scene construction process, including the optimization design of the model file, material file and construction steps. Aiming at the problem of single representation in virtual tourism system, this paper realizes the support of various media methods, including 3D object flash, video, audio and picture, etc. Through the hot spot system in this paper, not only the support for Flash in the 3D system is realized, but also the 3D model can be loaded and displayed on demand through the response of the hot spot, and the interaction between tourists and scenic spots can be improved. A new interactive roaming control method is proposed by studying the roaming mode of virtual tourism system. The WayPoint method and the shortest path finding algorithm are used to realize the tourists roaming along the shortest path between any two points in the scene. Through the optimization design of a series of roaming processes, the roaming can reach the real roaming effect. Based on the theory of user experience and the requirements of the system, the general functions of map and menu in the virtual tourism system are designed and implemented based on Flash. Based on the analysis of the bottleneck of the present virtual tourism system, this paper proposes and implements an online virtual tourism system based on Flash3D, the performance of which has been significantly optimized. It provides a reference for the large-scale application of virtual tourism in China.
