摘要
对与自由曲线有关的几何约束种类进行比较全面地研究,讨论了自由曲线应用到参数化设计系统中后几何约束的求解问题,提出可以用基于图的自由度分析方法对几何约束问题进行分解,介绍了简单凝聚模式下有关自由曲线几何约束的凝聚计算问题。
In this paper we carried out a more overall study on the types of geometric constraints related to free form curve and discussed how to solve geometric constraints when applying the free form curve to parametric design. Graph based analysis of free degree was proposed to he used to decompose the geometric constraints ; and the clustering computation of correlated geometric constraints of free form curve in the mode of basic clustering was introduced as well.
