摘要
讨论了鞋楦CAD中的曲线数学建模方法,首先提出了一种尖点识别方法,对鞋楦来说,该方法比一般的轮廓尖点识别方法更加简单适用,然后提出了利用三次B样条对鞋楦进行曲线建模的新方法。通过计算机编程实现表明,提出的两种方法提高了计算效率并能使插值精度得到保证。
This paper discusses the method of curve modelling in shoe last CAD. A simple and applicable method of recognizing cusp and a new method of curve modelling using cubic B-spline are presented. The implementation in computer indicates by the new methods not only the efficiency of calculation can be improved but also the interpolation precision can be ensured.
