Research And Design Application Of She Ethnic Group Ribbon Pattern Based On Shape Grammar

She ethnic group ribbon is an important decorative accessory in the traditional She costume,and it has a strong representation in the She handicraft culture.The She ethnic group ribbon pattern is closely related to the history and culture,religious beliefs,aesthetic style and national emotions of the She people,and its pattern modeling contains fixed elements of figure elements and shape derivation laws.Based on the theory of shape grammar,the thesis investigates the shape elements present in the She ethnic group ribbon pattern,the logic of shape grammar generation and its application in the design of modern cultural and creative products.The shape elements in the She ethnic group ribbon pattern include the basic form elements,the initial shape and the basic figure elements.The basic form elements include floating point and floating length;the initial shapes include triangle,diamond,polygon,wand flower and mouse tooth pattern;the basic graphics elements include graphic elements,symbolic elements and text elements.The logic of generating the shape grammar of She ethnic group ribbon pattern includes four levels of order: constraint of shape,selection of figure element,derivation of figure and fit of carrier.Among them,the shape constraint refers to the formal restriction on the shape of the pattern produced by some unchangeable statute conditions in the process of She ethnic group ribbon weaving.This limitation consists of three main sources,one of which is the molding of the process,the second is the qualification of the form,and the third is the statute of meaning.The selection of motifs refers to the selection of images according to the semantic connotation of the motifs,the agreed paradigm of combining motifs and the paradigm of linguistic logic when the maker of She ethnic group ribbon is designing the motifs.The derivation of patterns is the process of combining and deriving the basic figure elements in the She ethnic group ribbon pattern according to certain rules to form complex application patterns,including symmetry,repetition,rotation and addition and deletion and other types of derivation,which are also important derivation rules of shape grammar.The suitability of the carrier is the process of applying suitability to its pattern elements in the design of the She ethnic group ribbon pattern,which is an important modelling method for the application of the design of the She ethnic group ribbon pattern.Based on the study of She ribbon shape grammar,the thesis tries to apply the She ethnic group ribbon pattern to the modern cultural and creative product design.On the basis of design research and analysis,the initial shape of the She ethnic group ribbon pattern is extracted,followed by the design translation and shape grammar derivation of the basic figure elements to form the basic figure elements with the characteristics of modern design language,and the design derivation and application in modern cultural and creative products.In order to provide design cases and theoretical references for the application of traditional ethnic graphics in modern cultural and creative product design.
