中国古建筑的L系统建模新方法

中国古建筑的数字化保护问题日益成为计算机和建筑学科的研究重点,但其结构巧妙、类型丰富,且建模工程耗时等,给研究工作带来很多挑战。针对上述问题,提出了一种快速的数字建模方法,通过深入分析并抽取建筑特征,建立了古建筑L系统构件模型库及构件特征库,利用虚拟装配过程控制创建真实、精确的虚拟古建筑3D模型。结果表明,这种方法具有建模精确、生成快速等优点,可对中国古代建筑遗产进行有效的数字保护。

New model method for ancient Chinese architecture with L system

The preserving of the digital heritage for Chinese ancient architecture is the important part of architecture, and is becoming the research focus of computer researchers and architects. However, many challenges still exist in conducting pagoda modeling: the ancient Chinese architecture is of a great variety in structures and shapes, and the modeling task is time-consuming. To address these challenges, developed and applied a rapid digital modeling system in ancient Chinese pagoda. To implement the pagoda modeling system, this paper built a component model library of pagoda by L system and a corresponding component feature library in advance by deeply studying the Chinese architecture. The virtual assembly process ensured the coherent architecture styles of ancient pagodas. Because of the advantages (accurate modeling and rapid generating) of this mo-deling system, it can be applied to the preserving of the digital heritage in China ancient architecture.
