Study On 3D Fashion Simulation Of Garment Based On Texture Mapping

Third dimensional garment design system is one of significant field of garment CAD study with utilizing the mathematics, computer science and other discipline comprehensively. In the last few years, along with popularization of high definition colored graph equipments, the third dimensional design technology has obtained the promotion in each domain, and received people's attention increasingly due to its extremely rapid development. For example, it has been widely applied in cartoon making, city planning, molecular structure research, film & television advertisement, medicine, meteorology, geology, archaeology and so on . This is because during the computer-aided design, the designers always hope to see their preliminary design actually, as well as a lifelike picture. In the past, the consumption on manpower and material resources is huge using artificial protract or manufacture model to examine design effect. Moreover, along with the plan modifying, repeat plot and had repeatedly to draw a chart or repeatedly to manufacture the model to be done. If computer graphical display technology is selected, it is easy todemonstrate the third dimensional picture concerning the product by the screen, even observe its shell from different points of view. If the inappropriate places is occured, the interactive revision could be implemented on the shell directly by the screen. This kind of technology can reduce the manpower and the material resources greatly which shorten the design period and enhance the quality.Given the study on 3D fashion simulation of garment based on texture mapping is the following research of "the intelligent garment structural design system based on the fashion" which is the sub-project of Shanghai Education Committee's key discipline items of basic construction "the research on garment design and information digitization", this article receives the idea of garment fashion intelligence design system, in turn design demonstration module of three dimensional garment fashion on the base of idea. Therefore, it created the three dimensional controllable model, and created the corresponding three dimensional garment design according to the two-dimensional garment design ichnography based on the garment fashion intelligence design system and make the further study in algorithm and realization on the three dimensional garment design texture mapping which caused the user is allowed to see demonstration made by themselves any time, and make the design operation more easier to practice.The main ideas of this article included as following:Analyzed the condition on 3D garment CAD both in domestic and overseas, combined the situation of our country in which using 3D garment CAD, the necessity of developing three dimensional garment design possed our country independent intellectual property rights is proposed. According to the existing characteristics of garment fashion intelligence design, it proposed technical way on three dimensional garment fashion effect research, and give a short brief on the environment of software and hardware both for the reader to understand the full paper well.Chosen a standard module which is close to the two-dimensional module in garment fashion design intelligence system, combined the practical three dimensional data points gotten by the former through surveying this standard module, in person close standard person, treated the data in different laminations carefully, and used three transects interpolations in MATLAB to add certain amounts of three dimensional data,which ensure the smoothness in OpenGL protracting with Bezier curved surface. Because it is easy to get all data produced on the three dimensional model, the three dimensional model in this article is parameter-controllable.On the basis of three dimensional model, this article created threedimensional virtual capsid with changeable interspace volume model, regarding two-dimensional garment fashion ichnography as three dimensional garment fashion orthograph drawing. The paper utilized the method of three B transect to confirm and work out contour of three dimensional garment fashion, and achieved the sculpt point of curved surface on three dimensional garment fashion, especially made the certain, suitable account and deal with towards the data of collapsible, sleeve hole, and skirt-width in the MATLAB for the solid foundation for drawing three dimensional garment fashion.After obtaining three dimensional garment fashion sculpt point, resting on the idea of small curved surface piece connection, it constructs plan model of the three dimensional garment fashion curved surface, and realizes the three dimensional garment fashion curved surface of Bezier curved surface plan using the evaluation procedure in the OpenGL which means the three dimensional garment fashion demonstration is basically completed.In order to consummate the demonstration of three dimensional garment fashion, this article focus on the texture mapping technology of computer graphics which is applied to the demonstration of three dimensional garment fashion, and makes the analysis to illumination, the material quality and so on, and supply several demonstration drawings after textures mapping. The fact proved that, applying texture mapping technology to the garment fashion strengthens the garment's sense of stereoscopic and artistic.It summarizes the way to achieve three dimensional fashion demonstration based on the texture mapping, effect demonstration research realization way, analyzes the deficiencies, proposes the imagines and expectations for the further research in the future along with the current direction of in the domestic and overseas, and offers valuable references referring to further improvement & development on the three dimensional module of intelligence fashion design system.Concerning construct of three dimensional controllable model, the sculpt-point pick-up of three dimensional garment fashion curved surface, the texture mapping of three dimensional garment fashion and so on, this article is the important theory with these regards, whose technology and methods has greater reference value in the aspects of spinning and garment three dimension.
