Abstract

A technique of simulating the dressing process complying with the plan of garment's design, the mechanical properties of the material, each consumer's body, and multi-postures without a sample-making process is important as one of the elements in advanced-apparel CAD systems as well as a service for consumers. In computer graphics, it is difficult to clarify the interaction of the garment and the human body, if the shape of the human body is constructed in either a wire-frame model or a surface model. We tried to model the shape of the human body with primitives called meta-balls or density balls. One of the characters of meta-balls system is an operation called fusion. In Previous analysis one was not free to select fusion or nonfusion among meta-balls in constructing such model. In this paper, however, a method has been devised by which fusion or nonfusion may be freely selected, it is then possible to construct a human body model simulating the dressing process. Following that, the density distribution inherent in metaballs are utilized for calculating the contact drag of the garment and human body at various arbitrary contact positions. It is therefore possible to develop a basic mechanical algorithm which can simulate the dressing process, the shape of the garment changes along with the shape of the model.
