B-Spline样条线可以理解为一种插值曲线,以几个控制点来控制整条曲线。B样条产生于Bézier曲线之后,需要解决的主要问题有对曲线的局部控制和降低曲线的阶次。 B样条的想法是使用控制点和基函数来合成曲线,基函数…
实现方面,通过MATLAB类设计可以轻松构造B-Spline曲线。MATLAB代码通常包括计算基函数、处理节点向量、实现控制点输入等功能。对于NURBS(Non-Uniform Rational B-Splines),它在B-Spline的基础上增加了权重,以更精确地表示曲线,尤其是圆锥曲线。NURBS的实现通常基于已有的B-Spline框架,仅需额外处理权重计算。

在MATLAB中,实现B样条类涉及几个步骤。首先,定义span_index函数来找到给定参数所处的区间,使用lower_bound和upper_bound函数定位节点向量中的序号。然后构造BSpline类,接受控制点、曲线阶次和参数范围。如果参数少于4,将默认设置umin和umax。中间非重节点均匀分布,而重节点通过设置来实现。对于非均匀...
