摘要
这篇文章构造了带参数的三角Bézier基函数,并且引入调节矩阵,得到带形状参数l的二阶三角Bézier曲线。它既保留了Bézier曲线的性质,又具有形状可调性且能精确表示圆锥曲线。曲线拼接的条件简单,是G^n连续的。此方法具有一般性,为复杂曲线的设计创造了条件。
This paper constructs a series of trigonometric Bézier basis function with the shape parameters,adding adjustment matrix,and the two order triangular Bézier curves with shape parameter l are obtained. It retains the properties of Bézier curve. It is shape adjustable curves and it can accurately represent ellipse and circle. The curves are Gncontinuous and the condition of curves blending is simple. This method is general, which creates the conditions for the design of complex curves.
