Parametric Design Technology of Traditional Patterns Based on Shape Grammar

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.
