【摘要】：虚拟校园很好的整合了虚拟现实、计算机网络、信息系统,以及图形图像相关技术、计算机多媒体技术等相关领域的高新技术。这些高新技术能融合每一个建筑单体的组件以及相应属性的特征,为远程用户提供了模拟相应视听感官刺激的十分强大而且具有真实感的校园场景,从而很好的提供了一个直观的综合了解校园的基本状况的平台。本文借助虚拟相应的建模语言VRML,实现虚拟校园的漫游系统建立。本论文系统的研究了在建设虚拟校园时可能会碰到的种种问题,并在计算机对应的环境下面,利用VRML与3DS MAX互相集合的方式,来很好的表现出一个人机可以交流的漫游系统。本系统从设计流程到渤海大学校园漫游系统的设计结构进行的简要的阐述与说明,从技术层面分析了载入显示模块与表面颜色的交互实现过程,虚拟实体几何变换的交互实现,其中包括虚拟实体的平移、缩放、旋转的操作的交互实现,通过鼠标、键盘的操作完成交互的实现控制,碰撞检测的交互实现,最后从整体效果观察了渤海大学校园虚拟现实交互系统的自动漫游功能。本系统具有交互性、直观性、实时性、便捷性的特点,并且具有直观的感受和良好的视觉效果。用户通过本系统,可以从不同角度、不同视点浏览校园的建筑、风景效果,还可以在浏览过程中对指定场景景观进行简单的便捷的交互。
[Abstract]:Virtual campus is a good integration of virtual reality, computer network, information systems, graphics and image related technology, computer multimedia technology and other related fields of high-tech. These high and new technologies can integrate the components of each building unit and the characteristics of the corresponding attributes to provide remote users with a very powerful and realistic campus scene that simulates the corresponding audiovisual sensory stimulation. Thus providing a good intuitive comprehensive understanding of the basic conditions of the campus platform. In this paper, the virtual campus roaming system is established with the help of VRML-based virtual modeling language. This paper systematically studies all kinds of problems that may be encountered in the construction of virtual campus, and under the corresponding computer environment, using VRML and 3DS Max to set each other, to show a man-machine can exchange a good roaming system. From the design process to the design structure of the campus roaming system of Bohai University, the paper analyzes the interactive realization process of loading display module and surface color, and the interactive realization of virtual entity geometric transformation from the technical level. It includes the interactive realization of the translation, scaling and rotation of the virtual entity, the interactive control of the interaction through the operation of the mouse and keyboard, and the interactive realization of the collision detection. Finally, the automatic roaming function of the virtual reality interactive system on the campus of Bohai University is observed from the overall effect. The system has interactive, intuitive, real-time, convenient characteristics, and has intuitive feelings and good visual effects. Through this system, users can browse the architectural and landscape effects of the campus from different angles and different viewpoints, and can also easily interact with the designated scene landscape in the course of browsing.
