计算机系毕业设计网上虚拟校园摘 要虚拟校园是基于地理信息技术、虚拟现实技术和计算机网络技术等高新技术，将校园地理信息和其他校园信息相结合，以虚拟现实场景界面实现校园景观及信息的浏览查询，并可上载到计算机网络和提供远程用户访问。虚拟校园提供了校园景观及设施最直观的表现形式，方便了用户对校园信息的访问，促进了大学的建设和远程教学的发展。建立简单易行的现实感强的虚拟校园漫游便成为对大学校园虚拟化的目标。而VRML和3D MAX等相关软件也为虚拟校园提供了技术上的支持。本文的研究目的是设计并开发一个虚拟校园漫游系统，作者通过阅读大量国内外相关文献资料，深入地研究了虚拟现实技术和现有构造三维场景的语言，在此基础上，确定了基于VRML及浏览器插件技术的虚拟现实系统架构方案。首先，以虚拟场景构造的流程为线索，采用3Dstudio Max和VRMLPad实现虚拟场景对象的建模；针对建筑物建模的复杂度和真实感问题，提出了建筑物二次建模方法；其次，探讨了虚拟校园场景的交互。在此基础上实现了视点控制和动画交互。第三，在系统设计开发的末尾阶段，讨论对虚拟校园漫游系统的优化方法。通过碰撞检测、层次细节技术、纹理映射等技术方法优化系统。除此之外，还探讨了系统的整体构架、系统的开发流程、模型纹理贴图以及纹理贴图对场景外观的巨大作用。最后综合以上研究工作，设计并实现了一个基于VRML技术的虚拟校园系统。关键词：虚拟校园、虚拟现实（VR）、漫游、建模、纹理贴图、交互设计随着我国互联网的迅猛扩展, 多数大学的校园网已经建成。建设者原本设想的校园网是单纯的科技资讯传播工具, 而建成的校园网却是与国际互联网相联结的、空前强大的传播媒体, 是一个对学生有着强大吸引力的、对现存的政治体制、社会结构、文化传统、教育模式提出尖锐挑战的虚拟校园。在现实与初衷相悖的窘境中, 如何整合网上网下的教育资源, 如何应对网络对学生的政治信念、价值观念、伦理道德等非智力素质的负面影响, 如何依法对校园网实施科学的管理等等,都成为大学急需解决的问题。一、坚守培养现代全人的教育理念,对校园网络媒体的发展采取积极的政策现代教育应是全人教育。校园网是否有助于实现全人教育的理念, 这是首先要确定的。校园网有利于学术与科研信息的传播因而有利于开发学生的智力, 这是没有疑义的,分歧主要集中在它对学生的非智力因素的影响方面。自孔夫子、柏拉图、亚里士多德以降,古今中外的伟大教育家无不主张全人教育, 但现代“全人”与往昔“全人”是有区别的, 区别不仅在于德智体美的具体内涵多有不同, 更在于现代人要有鲜明、自觉的现代意识。今天的世界, 经济一体化、政治民主化、文化融合化已呈不可阻挡之趋势, 大学培养的“全人”的现代意识至少应包括观察问题的全球观念, 对多元文化的包容与借鉴意识, 自由、平等、民主、参与的社会意识, 团结、协调、互补、共进的团队意则是催化剂。互联网、校园网既然是一个虚拟的社会、虚拟的校园, 如同现实中的社会与校园一样,它对学生的影响就不会是完全积极的、向上的。我们不美化互联网,也决不赞同认为网上社会比现实社会更糟,更不宜于人才培养的观点[1]。有人认为互联网有利于西方文化的渗透, 其主要依据是网上信息为西方发达国家所垄断。他们认为这种状况会无形中助长青少年的西化倾向, 造成民族观念、爱国主义观念的淡漠。我们承认网上文化环境对人有潜移默化的影响, 但是, 网上信息来自西方的多, 来自发展中国家的少, 恰是现实世界中西方的科学与文化在全球范围内占主导地位的反映。我们只能承认和面对这个现实。更重要的是, 大学生、研究生已经有了足够牢固的民族文化根基, 网上之西化社会, 不足以动摇学生的爱国心与民族自尊心。想一想清末以来留学生在推动中国社会进步的斗争中所表现的高度爱国热情, 就可以知道, 那些担心西方的网上“霸权”、“文化侵略”可能使青年人的思想殖民地化的人, 其实是对民族文化缺乏自信。有人认为互联网的虚拟特征导致逃避现实的数字化人的出现, 使青年变成有人格与人际交往障碍、不能与现实世界中的现实人沟通的“视频白痴”。这种担心夸大了网上活动在青年日常生活中的时间比重和网络的吸引力。据北京师范大学“心理在线”网上调查,回答“网络有使人欲罢不能的感觉”、“在不上网的时候经常想着网上的事情”的人约为19%; 离开网络会感到恐惧和不快的人占26% [2 ]。对多数学生来说, 网络主要是了解国际时事、搜集学术与科研信息的工具。
