摘要
随着三维建模技术的不断发展,传统建筑的三维快速建模成为数字化保护的新手段。结合考古资料,运用CityEngine对中国特色古城墙的构建开展规则三维图库的模拟。以楼兰古城墙为例,使用二维GIS矢量数据标准格式,对城墙要素(如城垣、城台、登城踏步、女墙、角楼等)进行独立且高效的三维绘制工作。这种方式弥补了CityEngine只能对城市建筑模型或道路模型单独建模,缺少对两者综合建模的不足,扩大CityEngine在三维建模领域的应用范围。创建了符合中国古城墙三维建模的规则模板,为今后开展古城墙的建模工作提供一种强有力且可行的建模渠道。
With the developing of 3D modeling technology,3D rapid modeling of traditional buildings has become a new means of digital protection.Combined with archaeological data,this paper uses City Engine to simulate the construction of the ancient city wall with Chinese characteristics.Taking the ancient city wall of Loulan as an example,using the standard format of 2D GIS vector data,the city wall elements(rampart,the platform on the city wall,crenellated parapet wall,step in to city wall,turret,etc.)are rendered in regular,independent and efficient 3D.This compensates for the lack of comprehensive modeling of the two models that City Engine can only model separately for building models or road models.It expands the scope of City Engine’s application in the field of 3D modeling.Finally,the rule template which is in line with the 3D modeling of the ancient Chinese city wall is created,and provides a powerful and feasible modeling channel for the future modeling of the ancient city wall.
