摘 要
 随着虚拟现实技术的发展，通过计算机网络向人们展示的数字博物馆的优势也逐渐地体现出来，解决了传统博物馆文物难以保存和管理的问题。本文就此介绍了数字博物馆的基本理论、建设目标和研究内容，并分析了数字博物馆的核心功能模块，并基于虚拟现实技术，实现了博物馆馆藏文物的数字化、网络化和个性化展示过程。在3Ds MAX平台支持下，对数字博物馆展厅的平面布局、外部空间造型、内部空间构成、装饰材料及色彩等进行设计并建模，构建各种三维物体插入已构建完毕的展厅中；在此基础上，设置与视点相适应的照相机，再在带Cortvrml插件的浏览器中查看，实现场景的虚拟漫游。虚拟现实技术在构造虚拟场景中体现出较强的实时性、仿真性、交互性和灵活性。通过鼠标控制在数字博物馆中的自由漫游和自动全景漫游，展示了数字博物馆跨越时空的建设成果，以及虚拟现实技术在建筑设计导览领域的应用前景。

 Abstract
 With the development of virtual reality technology, through the computer network to demonstrate, the advantage of digital museum has gradually shown up, and the digital museum solves the preservation and management problems of heritages existed in the traditional museum. This paper introduces the Digital Museum's basic theory, construction goals and research contents, and analyzes the digital museum's core function, and based on virtual reality technology, it achieved digital networking and personalized display process of the museum heritage collection. Firstly, design and model for digital museum gallery site layout, the external space modeling, internal spatial composition, color and material etc. on 3Ds MAX platform, secondly, construct various three-dimensional objects for inserting into the previous finished construction of the gallery site, in the way, the construction of the gallery is completed. Finally after setting compatible with the viewpoint of the cameras, the browser with Cortvrml plug-in can view the scene as a whole and implement the virtual roaming. In the entire process, virtual reality technology reflects the strong real-time, simulation, interaction and flexibility. The Digital Museum of free roaming and automatic Panoramic roaming through controlling mouse show that the achievements of digital museum transcend time and space constraints and the virtual reality technology has a wide prospects in the architectural field.
