文化遗产数字化展示与互动技术研究与进展

以计算机图形学、虚拟现实（VR)、增强现实(AR)、计算机动画等技术为支撑的数字文化遗产技术，为数字化记录、保存、展示和利用文化遗产提供了丰富的手段。结合笔者所在课题组近20 a在数字文化遗产方面的工作，对文化遗产数字化展示与互动技术的国内外发展现状进行了综述，对其中的关键技术，包括数字化建模、数字化呈现和人机互动进行了深入讨论，并介绍了笔者在京杭大运河虚拟漫游系统和清明上河图动画与互动系统实现中的经验。最后，讨论了面临的挑战和发展趋势。

State of the art on the digital presentation and interaction of culture heritage

Digital Heritage is supported by the integration of computer graphics, VR, AR, computer animation and other techniques. There are rich methods for digitalized recording, storage, presentation and exploration of culture heritage. Based on the research and development work of the authors in the past 20 years in the field of digital heritage, the state of art on digital presentation and interaction of culture heritage at home and abroad is reviewed. Key techniques,in particular,on digital modeling, digital presentation and human-computer interaction are discussed. In addition, we present the experience in developing the interactive navigation system for Beijing-Hangzhou Grand Canal and animated Qingming Festival Drawing. Finally, We highlight the challenge and future trends in the field.
