Parametric Design Technology of Traditional Patterns Based on Shape Grammar

目的将现代参数化生成技术融入传统纹样设计方法,以此弥补传统的纹样设计方法对设计结果可控性低、产出效率低的不足,从而探索传统纹样创新设计的新途径。方法运用模件系统理论和图谱量化法提取传统纹样的文化基因图案,采用Grasshopper参数化工具重构纹样,并将形状文法推演规则转译为参数化语法表达的形状文法推演规则,运用系统的文法规则控制感性随意的纹样参数衍生流程,实现基于形状文法导向的参数化纹样设计方法。结果以黄梅挑花八角莲纹为例,编写形状文法控制的纹样衍生参数化程序,生成多种八角莲纹衍生图案,并应用于不同的文创载体。结论参数化设计逻辑下的形状文法可以更高效地挖掘传统文化纹样的创新设计价值,以形状文法为导向的参数化技术可灵活并科学地对传统纹样进行再设计,为数字化时代下非物质文化遗产的保护和传承提供参考。

The work aims to integrate modern parametric generation technology into traditional pattern design methods,so as to make up for the shortcomings of traditional pattern design methods in terms of low controllability of design results and low output efficiency,and thus explore new ways for innovative design of traditional patterns.The cultural genetic patterns of traditional patterns were extracted with the modular system theory and the graph quantification method.The patterns were reconstructed with the Grasshopper parameterization tool.The shape grammar derivation rules were translated into the shape grammar derivation rules expressed by the parameterization grammar.The systematic grammar rules were used to control the perceptually arbitrary pattern parameter derivation process,so as to realize the parametric pattern design method based on shape grammar orientation.With Huangmei picking flower octagonal lotus pattern as an example,the shape grammar-controlled pattern derivation parametric program was written to generate a variety of octagonal lotus pattern derivation patterns and applied to different cultural and creative carriers.In conclusion,the shape grammar under parametric design logic can explore the innovative design value of traditional cultural patterns more efficiently,and the parametric technology oriented by shape grammar can be used to redesign traditional patterns flexibly and scientifically,providing a reference for the protection and inheritance of intangible cultural heritage in the digital era.
