[Graph Drawing] 2003374315 DL : 0: 采用两种不同的方法绘制曲线 a）二次B样条曲线二次B样条曲线段的函数表达式为（1）其中为控制顶点。说明： ① 对任给定的一组控制顶点，每相邻三个控制顶点为一组进行曲线段绘制。即为一组，为一组，…，为一组，所有曲线段连在一起即构成了整个B样条曲线。事实上，前一条曲线段的终点即是下一条曲线段的起点。 ② 在每一段曲线的绘制过程中，取不同的值便得到曲线上不同的点。例如时，由公式（1）可得到曲线的起点，时可计算得到曲线的终点。为处理方便，可进行等距离选择，如10等份，依次取0,0.1,0.2…,1.0，从而可计算得到10个曲线段上的点，把这10个点依次连接，就可得到该曲线段。 b）四点插值细分曲线四点插值细分曲线的表达规则为其中为控制顶点，为细分次数，为顶点下标。即每细分一次，在任意两点之间插入一顶点。为方便处理起见，可绘制成封闭曲线。（初始）控制顶点保存在文件中。给定两个测试文件c1.txt，c2.txt-using two different methods of drawing curve a) quadratic B-spline curves of the second B-spline curves of expression as a function of (1) for the control vertices. Note :-given right of a group of control vertices per three vertices adjacent to a group Marche line drawing. Namely, a group of a group, ... to a group, all of the curves that together constitute the entire B-spline curves. In fact, a curve before the end of the next one that is the starting point of the curve. curve in every section of the drawing process, different from the value curve will be different points. For example, by the formula (1) available curve starting point, to be compiled at the end of the curve. To facilitate handling, for equidistance options such as 10 equal installments, in order, from 0,0.1,0.2 ..., 1
