摘要
Bézier曲线在 CAD、图形学等领域中有着广泛的应用 ,然而一直缺少理想的曲线绘制方法 .文中提出一种快速的 Bézier曲线的绘制方法 ,利用 Bézier曲线的离散割角性质 ,首先将 Bézier曲线自适应地递归离散分割为单调且方向一致的子曲线 。
Bézier curves have many applications in CAD field, especially in computer graphics, however there lacks fine and rapid drawing approach of it. A fast method for drawing Bézier curves is presented. By using de Casteljau algorithm, we first adaptively divide the curve into some monotone sub\|curves with definite directions, then generate the eight joined object lattice directly.
