计算机辅助服装设计的几何模型研究

Study of Geometric Model of CAD for Apparel

本文介绍用三次B样条函数建立服装衣片几何模型的方法,使衣片轮廓线及辅助信息统一地用三次B样条表示,并研究用于服装纸样设计(包括开省、省道转换、裥缝处理等)、推档、排料等的数学方法。计算机实现证明,该方法完全能满足服装设计的要求。

This paper presents a geometric model of apparel parts using 3 B-Spline, so the out- line and information of parts can be expressed in 3 B-Spline. It also discusses the realiza- tion of pattern design (including dart, dart-changing, pleat processing, etc.), grading, marking in garment design. Experiments indicate that the 3 B-Spline can meet the needs. The paper offers an effective mathematical method for building the CAD system for appa- rel cutting.
