The Research Of Personalized Dynimacal 3D Digital Garment Human Body Build Technology

With the high demand of clothing's fit well and personalization, the requirement of developing the 3D virtual try on system is more and more intense, "Virtual try on" is an emerging concept in the country, and it's also a new thing in other countries.There are many difficulties to be solved. At present, human bodies of the "Virtual try on" in the country are static and not personalized three-dimensional (3D) digital human bodies basically so that it can not meet the customer's demand better. How are customers allowed to experience with various actions whether the new clothes fit or not dynamically, and to appreciate the efforts of clothes under different light occasion, and then to choose the satisfied clothes? Based on this application required, this paper proposes a new method to implement the dynamic deformation of 3D personalized human body fast in order to provide a dynamic displaying platform for customers.This article compared variety implement method based on the research of dynamic deformation method of 3D personalized digital human body, and proposed a new method to quickly implement 3D digital human body dynamical deformation base on the deformation by example:Firstly, initialize process the 3D digital human body and rebuild the 3D digital human body which outputted by eMTM system to get the hands of 3D digital human body lay natural and locate the center of joint; Then, process the initialized personalized 3D digital human body data through geometric transformation and find out the data points involved in dynamical deformation to make a coordinate transformation, obtained a series of data file after transforming, thereby get a series of varieties pose of 3D digital human body; And then, combine the human body's seven parts'data which stored with blocks in the VRML file of obtained example into a common node, and make this node include a whole human body data information; Then get the geometry stored in the data files through the program, At last implement the key frame deformation between this series of geometry by the morph technology to realize the 3D digital human body dynamical deformation, and overcome the shortness of deformation by example that high-cost and time-consuming. Thus it provides a new implementation approach for the realization of 3D dynamic deformation of the digital human body and the dynamic display of "virtual try on".
