基于虚拟现实技术的南京鼓楼建筑情景复原

为了复原南京鼓楼最初的建筑形制动态情景变化,提出一种基于虚拟现实技术,并结合Cinema 4D三维建模软件的情景化数字复原流程。首先,对南京鼓楼的周边环境、建筑构件、室内陈设等进行研究,在现有测绘资料的基础上,进行艺术化的情景再现设计,并利用三维建模技术,通过模型复原真实的建筑形制。然后,结合虚拟现实技术,实现明鼓楼建筑与观赏者的情景交互设计。南京鼓楼初建于明洪武年间,后因历史变迁,其建筑规模、等级、做法均发生较大变化,导致明初鼓楼在每一个复建阶段的建筑定位仍然含糊不清。最终,通过虚拟现实技术,使南京鼓楼建筑形制能够以可视化的形式得以保存。在虚拟过程中,提出了简化且真实的古建建模交互策略,让用户通过沉浸式体验,直观地感受古建复原、修缮的过程。

Restoration of Nanjing Drum Tower Building Scene Based on Virtual Reality Technology

The work aims to propose a scene-based digital restoration process based on based on virtual reality technology and com-bined with Cinema 4D 3D modeling software, in order to restore the dynanic scene changes of the original building shape of Nan-jing Drum Tower. First of all, through the study on the surrounding environment, building components, indoor fumishings and so on of Nanjing Drum Tower, based on the existing surveying and mapping data, the artistic scene reproduction design was carmried ou,and the three-dimensional modeling tchnology was used to restore the real building shape. Then, the virtual reality technology was used to realize the scene interaction design between the Drum Tower of the Ming Dynasty and the audience. Nanjing Drum Tower was first built in Hongwu Period of the Ming Dynasty, and its scale, grade and practice had changed greatly with the historial chang-es, so that the architectural orientation of Nanjing Drum Tower in the early Ming Dynasty in each reconstruction stage was still un- clear. Finally, through the vitual reality technology, the building shape of Nanjing Drum Tower could be preserved in the form of vi-sualization. A simplified and real interactive strategy of ancient building modeling is proposed in the virtual process, so that uscrs can directly experience the process of ancient building restoration and repair through immersive experience.
