摘要
Ｂéｚｉｅｒ方法是计算机辅助几何设计中最重要的方法之一，本文研究了Ｂéｚｉｅｒ曲线的几何性质、绘图的数学原理和方法。我们用Ｃ语言编制了绘图程序，给出了四次Ｂéｚｉｅｒ曲线和分段四次Ｂéｚｉｅｒ曲线的图形。所得结果与理论分析完全一致。最后，我们使用代数方法完成了绘图定理的证明。
Bézier method is one of the most important methods in computer aidedgeomet rical desige.This paper discusses some geometric properties,plotting mathematic principles and methods on Bézier. A plotting program of C language is written.We have plotted quartic Bézier curvee and piecewise quatrtic Bézier curve.Finally,we have proved the plotting theorm by algebraic mothods.
