| As the representative of Chinese clothing culture,wedding dress has profound cultural heritage and emotional sustenance.From the development of the Zhou Dynasty to the Ming and Qing Dynasties,the modern "traditional wedding dress" slowly faded out of people’s attention after being impacted by the Western Cultural Thought of the Western Movement.The diversification of the cultural elements of wedding dresses has become an indispensable part of wedding clothing.At present,women’s Chinese wedding dresses on the market are mainly divided into two categories of traditional and improved design.The traditional Chinese wedding dress is mainly dominated by gown skirts and cheongsam.The gown skirts are mainly divided into three types: dragon and phoenix gown,Xiuhe clothing and Malay gown.With the rapid development of clothing production technology,traditional Chinese clothing culture and clothing digitization and customization technology The combination is bound to push the Chinese wedding dress to a new climax.However,at present,Chinese wedding dresses have problems in the actual production process,high costs,and cumbersome steps,and often use standard specifications as the basis for Chinese-style wedding dresses.These factors have greatly reduced the fitness of clothing,and cannot meet people’s requirements for Chinese wedding dresses to wear comfort and fit,while limiting the rapid development of the Chinese wedding dress market.This paper mainly conducts relevant research on the following problems in the generation of Chinese wedding dress models.First,in the academic research on Chinese wedding dresses,most of them are research on their marriage customs,etiquette,pattern morals and design applications.There are few research on their structure and model generation,and the methods of parameterized board have not been used.Second,the fitting of the curve segment of the clothing prototype is the difficulty of establishing a parameterization and familiar model.The integrity and continuity of each structure line of the clothing are important to parameter diagrams.It is difficult to achieve the requirements,and it is difficult to establish a correlation between graphics and structure lines.In view of the above problems,this paper focuses on how to realize the Chinese-style wedding model,and the main research contents and innovative work are as follows:(1)In this paper,the prototype method is used to generate the Chinese-style wedding model.Because the Japanese cultural female prototype accords with the basic characteristics of Chinese female body,meets the basic requirements before the change of various models,and is easy to construct the parameterized model,the eighth generation Japanese cultural prototype is selected as the Chinese wedding prototype.In the process of parametric generation of template,the fitting of curve segment is the difficulty of model establishment.In recent years,many scholars have put forward different ideas for curve fitting in clothing structure line,but most of them need to involve programming language or secondary development of software.at the same time,the fitting method of the curve is difficult to be accurately defined.In view of the above problems,this paper creates a curve fitting method based on multi-arc principle to fit the main curves in the Chinese wedding template.This curve fitting method can generate the curve part of the parameterized template more accurately and conveniently.Then through the corresponding constraints to determine the relationship between lines and arcs in the clothing template,so as to build a parameterized clothing template.(2)This paper takes the coat skirt in the Chinese wedding dress as the research object,and takes the dragon and Phoenix coat as the typical style to carry on the parametric design.First of all,by looking for the common ground of the Chinese style wedding dress structure of the coat skirt,and then combining the parameterized function of Auto CAD,taking the dragon and Phoenix jacket as an example,the parameterized model is constructed.Each part of the garment piece in the coat and the part related to the whole Chinese style wedding dress template are adjusted at the same time,and the functional parts of the lower skirt are divided into two parts:the waist and the skirt.The main constraint is that the waist length of the skirt is equal to the corresponding length of the sewing part of the skirt body,which meets the requirement of changing the original figure by modifying some parameters of a template,and then realizes the template generation from one style to multiple styles.(3)This paper proposes a method of using PYQT toolkit to realize the automatic connection of Chinese-style wedding parts and dynamically display Chinese-style wedding clothes.First of all,the parameterized dynamic block based on the cultural woman prototype is created based on the block editor of Auto CAD2018,and then the parameterized dynamic block prototype is designed according to the structural characteristics of the Chinese style wedding dress,in which the component module endows the template prototype with the parameterized function of the dynamic block,and the complex style can be further designed on the dynamic block template.At the same time,the Chinese style wedding structure resource library is established by using the tool palette group,and the dynamic blocks of the established components are added to the corresponding named tool palettes in turn,which is convenient to be used at any time when drawing.Finally,the corresponding program is written by using the PYQT toolkit to configure and present the clothing parts modules with a graphical interface according to their respective clothing characteristics. |
