摘要

随着三维数字技术的发展,三维虚拟技术逐渐向古建筑领域迈进。但目前对于古建筑建模学术研究较少,研究的大多古建筑的虚拟技术,都以三维建模软件为主。由于三维建模软件的局限性、建设模型数据量大,在大区域的三维虚拟化的应用中,无法体现地形,模型精度不高,位置精度有一定偏差。采用基于CityEngine的面向规则的三维虚拟技术,以阆中古城为对象,对地形处理、地形整平、古建筑结构分析、几何形状分析、空间位置分析、平移和旋转算法设计、附属设施的空间动态布局算法设计、规则编码等进行研究,实现了阆中古城的三维虚拟平台。通过实验证明了该技术的优越性,对今后古建筑的三维虚拟化建设提供了一种技术方法。
        With the development of 3D digital technology, 3D virtual technology is gradually moving to the ancient buildings, but there is little academic research on ancient building modeling at present. The virtual technology of most ancient buildings studied is mainly based on 3D modeling software. Due to the limitations of the 3D modeling software, the large amount of data of the construction model, the application of 3D virtualization in large areas can not reflect the terrain, the accuracy of the model is not high, and the positional accuracy has some deviations. We adopted the rule-oriented 3D virtual technology based on CityEngine. Taking LangZhong ancient city as the object, we studied the terrain handling, terrain leveling, ancient building structure analysis, geometry analysis, space analysis, translation and rotation algorithm design, ancillary facilities space dynamic layout algorithm design, rules of coding, etc. 3D virtual platform of LangZhong ancient city was achieved. The advantages of this technology are proved by the experiment. The technology provides a technical method for 3D virtualization construction of ancient buildings in the future.
