| 摘 要： | 三次B样条曲线在实际工程中得到了广泛应用,在目前的文献中还未查到任意个控制点的三次B样条曲线绘制系统。为了使B样条曲线得到更广泛应用和方便《计算机辅助几何设计》课程关于B样条曲线的可视化教学,本文用MatlabGUI编程设计三次B样条曲线绘制系统。此系统界面简洁,使用方便。可用鼠标在屏幕坐标系上点击输入任意个控制点,也可用文件方式输入任意个控制点。用矩阵描述B样条曲线方程,实现快速计算并绘制出光滑的三次B样条曲线。

| Abstract: | The three B-spline curve in the actual project has been widely used. The three B-spline curve drawing system of any control points has not yet been found in the current literature. In order for B-spline curve to be more widely applied and for the Computer-Aided Geometric Designcourse on the B-spline curve visual teaching to be user-friendly,this paper programms the three B-spline curve drawing system with Matlab GUI. The system interface is simple and easy to use. The screen coordinate system can be clicked... |
