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。
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 Design＂course 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 with the mouse to input any control points. Any control points can also be entered by file way. B-spline curve equation may be described with matrix to achieve a quick count and draw a smooth curve of the three B-spline.
