基于形式语法的建筑设计细胞衍生法研究

摘要

Computer-aided design tools which are available currently have been providing effective support for the later stages of the architectural design process. For the initial stage of architectural design, in which design concept is mature whereasthe structure and shape are not determined, a new kind of solution should be needed to support designer¢s way of thinking and inspire the creation of design. Thus, in this paper, a new method of architectural generation based on shape grammar is proposed to describe the animation of the complex 3D forms. It tells how to create an initial shape by limited rules, then automatically generate genetic shapes, and finally grow into a complex system by modifying the adaptable rule. Also, the developed shape grammar framework allows designers to actively participate in the generation process. Finally, the modeling of CFS wall prototype is taken as an example to verify the effectiveness and practicality of this method.%目前可用的计算机辅助设计工具，为设计开发过程后期阶段提供了相当有效地支持，但对于设计初始阶段，即设计思路成熟、但设计的结构和形状还未确定之时，需要一种新的CAD解决方案来支持设计者思维方式并激发创作灵感。因此，提出一种基于空间形式语法的建筑设计生成方法，描述复杂空间形体如何自动派生——通过限定的规则产生初始体块，在规则内生成与初始体块相似体块，再而改变局部可变规则生成多样复杂的系统，同时允许设计者积极参与整个生成过程。以CFS墙体原型建模为例，验证该参数化建模方法的有效性和可行性。
