清式角科斗栱的形态分析与展示综述
摘 要：斗栱作为古木建筑的重要构件历经了多个朝代的演变，到清朝时斗栱的形制由《工程做法》详细规定，角科斗栱的形态比柱头科和平身科更复杂，因此需要经过参数化建模对其构造进行拆分组合，并且利用三维可视化设计分析清式角科斗栱的形态，能够给人以直观清晰的感知，利于古木建筑的教学以及修复保护工作。

The Analysis and Display of Corner Corbel-Brackets in Qing Style
Wu Yue (170409128)
Abstract: Dougong, as an important component of ancient timber architectures, went through the evolution in the different dynasties and to the Qing dynasty, the structure of dougong had been prescribed in detail. Comparing with the column corbel-brackets (dougong) and intermediate corbel-brackets (dougong), the structure of corner corbel-brackets (dougong) are more complicated, so we need to take apart and combine the elements by parametric modeling. Whatrsquo;s more, using the 3D visualization design to analyze the construction of dougong can give people with clear and intuitive perception, which is beneficial to the educational work and protection work of ancient timber architectures.
Keywords: Dougong in Qing style; Corner Corbel-Brackets; 3D visualization design; Parametric modeling
梁思成先生在《清式营造则例》中注解：“多数曲木与斗形木块结合在一起，用以支撑伸出的檐者，谓之斗栱。”我国西周时期出土的青铜器证明柱子上已经使用了栌斗；汉代是斗栱形式开始丰富的时代，斗栱形象成为等级的标志，结构上以一斗二升和一斗三升为主；人字栱的出现成为南北朝时期突出的特点；唐宋时期斗栱的出跳形式被确定下来并增加了昂的使用，重栱造和偷心造是主要标志；元代则出现了假昂；明清时期斗栱装饰化，结构作用退化[4]。
