Study On Display Of Virtual 3D Fashion Pattern And Wrinkle Effect

GCAD(Garment Computer Aided Design)technology has developed almost thirty years.Fashion Production has been more effective and product quality has made great progress with the help of this high-tech tool. Computer application, which has been more and more popular, is widely used in the tradtional fashion design industry with the push of GCAD.It is believed that the frontier of GCAD research is in 3D GCAD field. It provided a human model based on 3D environment, so It was totally different from 2D GCAD. In 3D environment, garment design was no longer 2D shape made of paper, but was real clothes which can be put on VR human body.This technology also provided a multifunctional and powerful system.The precision of fashion products and productive efficience can be greatly improved.My research was based on Intelligent Style-based Garment Pattern Structure Design System, which was one of national key projects.It was designed for non-professionals or amateur designers to finish the design work through simple human-mechine operation. My thesis presented the structure of main system, realizes the VR human body and fashion pattern, analysed the generating algorithim, designed friendly humanmachine interface, and implemented the wrinkle effect of specific pattern at last.The main research work of my thesis contains as follows: The development and status of fashion CAD in the world were summarized at first.then the paper pointed out that it was not mature enough in the development of fashion design CAD. After analyzing the requirements of garment market in china, we got the conclusion that it is necessary to develop the system for intelligent fashion design.Then the basic principle of intelligent design fashion system in 2D environment was analyzed.That is, dividing the pattern into several main parts(like collar,clothes piece,sleeve,skirt and so on)Because of the benefit, the garment design process can be turned into combination process of main parts.Meanwhile, we also discussed the generating principle of 3D data from 2D garment shape,provided software and hardware developing envrionment of our sub-system. All the steps made us discussing data transfer from 2D to 3D and further development of 3D module very effecient.After analyzing the Intelligent Fashion Design System and considering the basic human-machine design principle,We developed a friendly 3D fashion display window with VC++ and OpenGL technology.Data integration and usage were assured because data processing was did by Matlab,data save was did by Access,data usage just related to VC programme.As above,Our main work was the design of 3D sub system for Intellgient Fashion Design System.There were main steps of the work.First,GUI had to be designed.Second,Human body,which had to be under our control eazily had to make by combining surfaces.Third, 3D surfaces had to be darwn in order to simulate fashion pattem.Fouth,some special environment parameters had to be added to our fashion to make it looks real.Finalry,efficient algorithim of wrinkle effect simulation was disussed at the end of the paper. In conclusion, the paper put forward a series of plans to realize the displayof 3D fashion pattern and wrinkle effect based on Intelligent Fashion Design System under concrete engineering background.It was valuable both in the theory and application and can provided instruction to the development of fashion CAD in the modern textile engineering field.
