摘要
对基于曲线的参数化技术作了研究与分析。提出了实现曲线参数化的六个基本要素,即曲线的分类;曲线尺寸的提取研究;曲线基本约束关系的归纳以及约束的语言文法表示;曲线、曲面的几何拓扑网状结构表示;约束的求解与几何推理;约束关系的满足方法。对其中的曲线尺寸作了探讨,并重点研究了曲线的约束关系满足方法。最后作了实例分析。
In this paper, the parametric design technology for curves is studied and analyzed. And six key points of curves parametric design are proposed that include the classification of curves, the extraction of curves dimension, the induction of basic constraint relations, the geometrical and topological structure representation of curves and surfaces, the geometric reasoning method for constraints, and the satisfaction way for constraints. The dimensions of curves are discussed. And also the satisfaction method of constraint relations among curves is researched. Finally, an example is analyzed.
