Research Of Constructing Three Dimension Mannequin Theories And Abecedarian Of Simulating Garment Virtual Try-on

Currently, along with the universality of the network and the development of virtual reality, the technique of domestic and international garment CAD is gradually maturing, and has becomed to commercialize. Because of the garments that put on the complicated three dimension human bodies are stereoscopic, this makes the technique of Two Dimension Garment CAD and its related technology trend to be stereoscopic, intelligent, integrated. Among of them, Three Dimension Garment CAD,Virtual Try-On and Digital Garment Tailor are important subjects which are concerned and investigated in domestic and international academic circles in recent years.Three dimension Garment Virtual Try-On System is an important part of the Three Dimension Garment CAD, and it is the development direction in the current garment CAD field. The effects of Try-On system will be seen before the garment being created through Three Dimension Garment Virtual Try-On system, this point not only helps garment designer to conceive better, but also lets customer make the idealest choice conveniently and fastly according to the effects of Try-On system.Then, it not only effectively decreases the enterprise's running cost, but also consumedly increases the sale quantity of the clothing product.Based on the related theories of Three Dimension Garment CAD technique, this thesis is aimed to realize three dimension human body modeling, and to analysis three dimension garment curved face and the effects of try-on detailedly,using the technical support of fabric and clothing, computer graphics etc, and also making use of the research of three dimension the human body, garment model, and mathematics, digital image manipulation technique etc.To re-construct three dimension human body, the related information about mannequin surface must be mined first. The common methods of obtaining mannequin surface information is briefly introduced in the thesis at first. Because of the facility restraint, the data uses in this paper referred to reports and papers of other researchers. In details, to read out vertex information of human body from a 3DS-formatted file that is extracted from the design model by the application of professional 3D human body modeling software.Then, according to the applied characteristics of the garment CAD, a new triangular subdivision method is applied in human body curved face modeling realization. Put simply, it requires to implementing effective triangular subdivisions of mass data point on the human body model and reconstructing human body by the help of minor triangle chip approximation.
