摘要
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。用Matlab GUI编程设计了"三维空间的三次B样条曲线绘制系统"。此系统界面简洁,使用方便。可用键盘输入任意个控制点,也可用文件方式输入任意个控制点;用矩阵描述三维空间的三次B样条曲线方程,实现了快速计算并绘制出光滑的三次B样条曲线。
In order for B-spline curve to be more widely applied and user-friendly ＂computer-aided geometric design＂ course on the B-spline curve visual teaching.The ＂three-dimensional space of the three B-spline curve drawing system＂ is designed and programmed with matlab,which is simple and easy to use.Any control points,can be input by keyboard or paper.Matrix describe the three-dimensional space of the three B-spline curve equation to achieve a quick count and draw a smooth curve of the three B-spline.
