计算机辅助服装纸样设计的算法原理与实现

本文对服装的工艺特征进行分析,提出了适合于服装设计的基本算法——放样变换。该算法很好地解决了服装设计中对图形的各种变形处理要求。本文还给出一个基于上述算法的服装CAD系统的实现方法。     

A NEW SYSTEM FOR COMPUTER AIDED PATTERN DESIGN——CAPDS

This paper proposes a new computer aided pattern design system(CAPDS)in which a uniformmathematical expression is used to construct different objects. In the geometric model, 3 B-splineis adopted as a line model. The new system with uniform mathematical expression has the distin-guishing features: curve smoothness and fidelity, convenience to process graphic data in thedatabase and etc.. This paper presents the data structure, the program structure and also the implementation.
