Research On The Individual And Dynamic Virtual Human Modeling System For Electronic Made To Measure

With the increasingly development of computer software and hardware, many industries are used to trying a new way to manufacture their products. Combined with computer application can simplify the complicated work. The research of how to use computer technology in the clothing industry is getting more and more focus. eMTM (Electronic Made to Measure) is a brand new mode of clothing production in the 21st century, it is a more advanced conception to MTM (Made to Measure). eMTM utilizes 3D body scanning technology, computer technology and network technology to combine body measure, figure analysis, style choice, clothing design, clothing exhibit, order, production together. Besides, it has realized a convenient and highly effective digitized chain of the clothing production.It is very favorable to exhibit the impression of the dressing by a dynamic virtual human model, so the dynamic virtual human modeling is an important part of the eMTM system. This paper describes an individual and dynamic virtual human modeling system for eMTM. The system analyses the data which generated from a body scan system and reconstructs the data by adopting the draft specification of the Humanoid Animation Working Group(H-Anim) which defines a humanoid model structure which can be viewed using any VRMIL2 comliant browser. We use forward kinematics to make the humanoid model animate, and avatars based on the H-Anim specifications are generally composed of a set of body surfaces, which do not ensure satisfying continuity between connected body parts. This paper proposes a generic method for performing real-time body deformations.Besides the virtual human modeling, this paper proposes the method of reconstruction the human surface date which keeps the virtual human model's individual. In order to exhibit the virtual human model dynamically, we takes the advantage of the H-Anim standard and Java3D, and stores the virtual human model's data with the treelike structure. This paper do the research of how to store the virtual human model's surface data with different level, by this way it can solve the discontinuity between connected body parts when the virtual human model is moving.
