基于Julia集的潮汕抽纱装饰纹样分形设计

Fractal Design of Chaoshan Drawing Decorative Pattern Based on Julia Set

分形普遍存在于自然环境的微观之中,在农业上常用于土壤特征与农作物结构等的分析。分形图案因其生于自然的特点,在解释自然结构的同时具有艺术性,与传统植物纹样搭配相适应。农作物作为潮汕抽纱纹样的主要题材,文章提出基于Julia集的潮汕抽纱植物装饰纹样分形设计模型,试图更好地实现潮汕抽纱数字化,提供符合当下审美的分形纹样设计,缓解自20世纪90年代工业化冲击后,抽纱从业人员凋零,缺乏从事其纹样设计人员的现状。通过对葡萄、麦穗、花卉等纹样进行归类与分形维度的计算,总结潮汕抽纱植物纹样的分形特征,应用分形艺术软件UF6完成分形纹样设计,与传统潮汕抽纱植物纹样遵循类别、形制进行组合。最后,针对青年群体进行模型输出结果的问卷调研,从民族性、创新性、艺术性、喜爱度验证分形引入潮汕抽纱的可行性,并邀请非遗工作者从生产角度做出评价。结果表明:潮汕抽纱可通过分形设计扩充新的纹样素材,青年群体希望潮汕抽纱能以局部装饰的形式融入日常应用的产品中。在生产上,根据应用于织品、印刷等不同需求,对分形纹样的复杂程度作出考量或简化,为刺绣织品图案的创新设计提供参考,展现分形通过农业所表现的艺术性。

Fractals exist in the micro of natural environment and are often used in agriculture to analyze soil characteristics and crop structure.Because of its natural characteristics,fractal patterns are artistic while explaining natural structures,and are compatible with traditional plant patterns.Crop is the main subject of Chaoshan drawing pattern.This paper proposes a fractal design model of Chaoshan drawing plant decorative pattern based on Julia set,in an attempt to better realize the digitizing of Chaoshan drawing,provide fractal pattern design that is in line with the current aesthetic,and alleviate the situation that after the impact of industrialization in the 1990s,drawing practitioners have been declining and lacking of pattern designers.By classifying grape,wheat,flower and other patterns and calculating fractal dimension,the fractal characteristics of Chaoshan drawn-plant patterns were summarized,and fractal art software UF6 was applied to complete fractal pattern design,which was combined with traditional Chaoshan drawn-plant patterns according to category and shape.Finally,a questionnaire survey was conducted on the output results of the model for young people to verify the feasibility of introducing fractal into Chaoshan drawing from the perspectives of nationality,innovation,artistry and fondness,and intangible cultural heritage workers were invited to make evaluations from the perspective of production.The results show that Chaoshan drawing can be expanded into new pattern materials through fractal design,and young people hope that Chaoshan drawing can be integrated into daily products in the form of local decoration.In terms of production,the complexity of fractal patterns is considered or simplified according to the different needs of textiles and printing,so as to provide a reference for the innovative design of embroidery fabric patterns and show the artistry of fractal through agriculture.
