【摘要】：虚拟博物馆采用了计算机图形技术、多媒体技术、人机交互技术、网络技术、立体显示技术及仿真等技术(也可总称为虚拟现实技术VirtualReality)来呈现传统文化遗产。虚拟现实技术(VirtualReality)(简称VR),又称“灵境技术”,“虚拟环境”、“赛伯空间”等,它是以计算机技术为主,利用计算机特殊的输入、输出设备来营造一个“看起来像真的、听起来像真的、摸起来像真的、嗅起来像真的、尝起来像真的”多感官的三维虚拟世界。将虚拟现实技术应用到虚拟博物馆的建立当中,为实现历史文化遗产的保留与发扬光大提供了保障,能使体验者在游览虚拟博物馆并与之交互从而产生新的碰撞与冲击,使之有着新的感受与体验。然而,三维建模技术和交互技术的应用在虚拟博物馆的展示中起着非常重要的作用,是整个虚拟博物馆建立的基础。目前,世界各大博物馆基都相继的利用文字、图片、视频以及交互媒介举办各种各样的虚拟展览,这为我们的三维建模技术和交互技术的研究提供了一个很好的平台。本论文从论述虚拟现实技术系统为出发点,将虚拟现实应用到虚拟博物馆中,并阐述了整个虚拟博物馆建立的过程及理论依据,该虚拟博物馆通过计算机三维建模技术将已经不复存在的一些有特色的石库门及其他一些优秀的历史建筑进行建模再现,使体验者能够虚拟的经历整个石库门里弄建筑的演变,了解整个建筑的装饰特点,并且通过进行材质的选择及其他一些家具的位置的摆放等进行趣味互动,使整个文化遗产得到更好的更广泛的传播。本论文研究的主要内容和研究成果包括: (1)虚拟博物馆艺术相关理论的分析及设计要点:在艺术理论研究方面,从建筑的美学出发,研究石库门虚拟博物馆的布局、门头及门窗等设计原理,再进行石库门虚拟博物馆的整体设计。同时,在博物馆内部展品方面,项目组查阅了大量的图书史料,将很多已经很难找到的历史文物呈现在虚拟博物馆中。 (2)虚拟博物馆建模技术理论支持及解决技术难题:三维模型的建立及模型整合方面,利用LOD技术进行面片的处理,以减少计算机运算量从而加快整个系统的运算速度,从而达到系统的实时效果。模型贴图制作方面,利用史料、拍照收集及平面软件进行贴图的绘制等方式进行贴图的制作,从而达到真实性与便捷性。 (3)虚拟博物馆交互研究及实现:利用Quest3D虚拟平台进行虚拟博物馆交互的建立工作,研究虚拟博物馆建筑构件及内部展品导入到虚拟平台中的方式及设计方法,从而实现交互平台运行的实时性及流畅性。 (4)石库门虚拟博物馆实施后期反馈信息研究:利用眼动仪信息采集工具,对石库门虚拟博物馆建立后实施情况进行信息的收集与反馈,找出整个虚拟博物馆设计的优点及不足之处,为后续工作提供理论依据。
[Abstract]:Virtual museum uses computer graphics technology, multimedia technology, human-computer interaction technology, network technology. Techniques such as stereoscopic display and simulation (also generally referred to as Virtual reality) are used to present traditional cultural heritage. Virtual reality. Also known as "spirit technology", "virtual environment", "cyberspace" and so on, it is based on computer technology, the use of computer special input, output equipment to create a "look real, sounds like real." 3D virtual world that feels like real, smells like real, tastes like real "multi-sensory virtual world." apply virtual reality technology to the establishment of virtual museum. In order to achieve the preservation and development of the historical and cultural heritage, it can make the visitors visit the virtual museum and interact with it to produce a new collision and impact, and make it have a new feeling and experience. The application of 3D modeling and interactive technology plays a very important role in the display of virtual museum, which is the foundation of the whole virtual museum. At present, all the major museums in the world use text one after another. Pictures, videos and interactive media hold a variety of virtual exhibitions, which provide a good platform for our 3D modeling technology and interactive technology research. From the point of view of virtual reality technology system, this paper applies virtual reality to virtual museum, and expounds the process and theoretical basis of the establishment of the whole virtual museum. The virtual museum through the computer three-dimensional modeling technology will no longer exist some of the unique Shikumen and some other excellent historical buildings to model and reproduce. So that the experience can experience the evolution of the whole Shikumenliong architecture, understand the decorative characteristics of the whole building, and through the selection of materials and other furniture placement and other interesting interaction. The main contents and results of this thesis are as follows: 1) Analysis and design essentials of the related theories of virtual museum art: in the aspect of art theory research, the design principles of the layout, door head and door and window of Shikumen virtual museum are studied from the view of architectural aesthetics. At the same time, in the museum's internal exhibits, the project team consulted a large number of books and historical materials, and presented a lot of historical relics in the virtual museum which are already very difficult to find. 2) Virtual museum modeling technology theory support and solve technical problems: 3D model establishment and model integration, the use of LOD technology for face processing. In order to reduce the amount of computer operation so as to speed up the operation of the whole system, so as to achieve the real-time effect of the system. In order to achieve authenticity and convenience, photography collection and graphic software mapping are used to make the map. Research and implementation of virtual museum interaction: using Quest3D virtual platform to establish virtual museum interaction. This paper studies the way and design method of importing the architectural components and internal exhibits of virtual museum into the virtual platform so as to realize the real-time and fluency of the interactive platform. Research on feedback Information of Shikumen Virtual Museum: collecting and feedback on the implementation of Shikumen Virtual Museum after the establishment of Shikumen Virtual Museum by using the information collection tool of eye movement instrument. Find out the advantages and disadvantages of the whole virtual museum design, and provide the theoretical basis for the follow-up work.
