摘要:
通过对鞋楦曲面的外形分析,采用网状分布的定位结点来表示鞋楦的外形特征.在 IBM PC/XT 个人计算机上,用双三次非均匀 B 样条反算的方法对网络化后的楦面进行一次性拟合,避免了曲面拼接,获得了光滑、连续的楦面模型.用回归分析法对传统展平方法进行了分析、总结,提出了一种新的展平算法,得到了实用、一致的楦面展平图.
Abstract:
The last is represented by the patchwork arrangement nodes in order to get its features through IBM PC/XT personal computer,the nodes are inter- polated by a parametric non-uniform bicubic B-spline function,so as to avoid the surface synthesis and obtain a continuous and smooth form model of the surface of last.Based on the analysis and summarizations of the traditional flattening methods,a new algorithm is developped by means of regression and a useful flattened form of the last is obtained.
