Parametric and regeneration design of Badayun patterns

为提升传统纹样创新设计效率,提出了一种参数化解构和再生设计方法。以八达晕纹样为例,在解读其艺术价值和形态结构的基础上,将其划分为填充、装饰、骨架3类元素,分别拆解为基本图元;各图元参数量化后,构建形态拟合公式,利用Rhino软件建立基础纹样模型;此基础上,通过调整不同参数,生成不同形制的纹样。并进一步,对生成纹样内部区域进行自动赋色。结果表明,基于八达晕纹样的参数化图案设计模型可衍化出不同风格效果的近似纹样,拓展纹样生成的丰富性;相较于传统设计方法,该方法实现由线稿、结构、赋色的一体化设计,为当代服饰纹样再生方法提供参考。

Objective Traditional patterns possess rich cultural connotations and unique aesthetic characteristics.This study aims to reinterpret and recreate the morphological composition of traditional patterns,injecting them with a sense of contemporaneity and innovation.By doing so,it seeks to infuse contemporary designs with distinctive artistic charm and provide consumers with diverse choices and cultural experiences.Currently,researchers primarily focus on the cultural connotations and formal composition of patterns,resorting to manual drawing for their reinterpretation,while lacking applications for rapid digital generation.To enhance the efficiency of innovative design for traditional patterns,a parametric deconstruction and regeneration method is proposed,enabling the rapid generation of pattern forms and color variations.Method This study focused on the Badayun patterns,analyzing its artistic value and morphological structure.The patterns were divided into three categories,i.e.,filling,decoration,and skeleton,which were further deconstructed into basic graphical elements.By quantifying the parameters of each element,a morphological fitting formula was constructed.Modeling was then carried out using Rhino software and its Grasshopper plugin to establish a foundational pattern model.The model included the establishment of pattern deconstruction,primitive library,parameter library,rule library,and parametric expression and recombination,which eventually formed patterns with different shapes and parameters.Furthermore,color extraction and clustering algorithms were employed to extract and cluster colors from different scenarios,resulting in diverse color schemes.Additionally,automatic coloring was applied to the interior regions of the generated patterns.Results By combining traditional patterns and parametric modeling techniques,this study presented a parameterized deconstruction and regeneration method based on the Badayun pattern.The method successfully achieved the parameterized regeneration of traditional patterns with different forms and color styles.Using the floral element of the Badayun patterns as an example,the element was deconstructed parametrically to generate locally varying graphical effects under different parameters.Furthermore,an improved binary K-means adaptive clustering algorithm was employed to extract color factors from samples,yielding color analysis charts of typical Badayun patterns from different periods.It included the main colors of the Badayun patterns in the Song,Ming,and Qing dynasties,the RGB values of the corresponding main colors in different periods,and the color proportions of different colors in the overall pattern.Based on the generated line drawings of patterns in different forms,an automatic transfer coloring algorithm is utilized to derive various coloring effects for the same pattern.The welldesigned Badayun patterns could be applied in multiple fields and transformed into product textures through a parametric platform,facilitating aesthetic dissemination and transforming functional utility in various products.It formed a new way of transforming the qualitative expression of pattern regeneration design into quantitative expression,which could quickly generate a large number of traditional pattern design schemes and effectively improve the design efficiency.Conclusion This paper proposes a parametric model-based design method for Badayun patterns,which can generate different styles of patterns according to different parameter settings.The method uses computer technology to achieve an integrated design of line drawing,structure,and color assignment,which can quickly and flexibly adjust and control the form and style of the patterns,compared to the traditional design method.The method improves the design efficiency and creativity.Through case analyses,the paper demonstrates the application value of the method in garment pattern regeneration design and graphic design in the digital era.The parametric modelbased design method for decorated lattice patterns provides an effective technical means for the regeneration and innovation of traditional patterns,and a new entry point for graphic design in the digital era.
