Trimmed NURBS surface applications in computerized 3D fashion design for garment industry

Purpose: The purpose of this paper is to introduce an approach to generating a basic bodice based on human body structure. The trimmed non-uniform rational B-spline (NURBS) method is applied to develop computer-aided tailoring and styling capabilities in 3D fashion design. Design/methodology/approach: Based on the body structure of the scanned subject, a parameterized method to intuitively generate adaptable bodices is proposed. NURBS surfaces are applied to provide an interactive styling design based on the preset bodice. To mimic dress shearing for any specific requirement, trimmed curves are applied to the NURBS-based clothes. A simple periodic function is introduced to develop a wave-like style garment. Findings: Newly-styled apparel designed in the third dimension is much more intuitive than conceptual drawings on paper. In order to create wearable garments using the computer-aided apparel design tools, the expertise of pattern makers is necessary. Originality/value: Interactive free form surface creation and its associated techniques, by means of trimmed NURBS, are applied to computer-assisted garment design in three dimensions. The technique provides the designers with a more freely expressive means of creativity.
