Part I: system kernel and formulas

Purpose – This ongoing research revolute the conventional clothing design process by garment constructions in truly three dimensions rather than in two dimensions by ways of pattern design. The aim of the research is to develop a computer‐assisted clothing design tool in complete three dimensions. It would provide the garment designers the capabilities of 3D basal garment creation, restyling, and static fitting analysis when wearing on a digital mannequin. The kernel of the design environment and the mathematical formulas used in garment creation are described, results and implementations will be presented later in part II of this paper.
