提出了一种新的基于包络曲线模板的曲线造型方法。作为包络模板的理论基础,通过对给定数据点的重复插补生成一族插补曲线族。在此基础上,引入了一族单参数插补圆柱曲面族,给出了包络条件及其包络曲面,并以包络条件的基准线作为曲线造型的原型。通过分析包络基准线的几何性质,推导出相邻两段曲线在公共点处的连续条件。在技术层面,构造包络曲线模板,利用包络模板扫描数据点,可以得到期望的G2或C2复合曲线。
This paper proposes a novel curve modeling method based on an envelope curve template. As the theoretical basis for the envelope template, a family of interpolating curves is generated by repeated interpolation of the given data points. On this basis, a family of one-parameter interpolating cylindrical surfaces is introduced, and then the envelope condition and its envelope surface are given, and the directrix of which serves as the prototype for curve modeling. After analyzing the geometric properties of the directrix of the envelope, the continuity conditions of two adjacent curve segments at the common point are derived. At a technical level, an envelope curve template is constructed, and the expected G 2 or C 2 composite curves can be obtained utilizing the envelope template sweeping over the data points.
