The Innovation Design of Traditional Chinese Auspicious Patterns Based on Shape Grammar

The artistic expression of traditional Chinese auspicious patterns in modern design is unique and charming, and it is intersecting more and more with modern design, and there is a lack of scientific methods to analyse traditional Chinese patterns from the perspective of Western composition. The objective of this study is to explore the translation path of traditional Chinese auspicious pattern design and realize its protection and reuse. The literature analysis method is mainly used to analyse the theme and cultural connotation of the pattern, the pattern and colour are extracted by using the mapping software, the pattern and colour factor library are constructed, and the shape grammar is used to evolve the pattern design. As a result, a new pattern design scheme is generated by using the law of formal beauty, and the feasibility and effectiveness of shape grammar in the innovative design of traditional patterns are demonstrated.
