For the other four leaf shapes - spathulate, denta-spathulate, cello-shaped and deltoid - more segments of Bezier curves were necessary for a good fitting.
对于三角形、匙形、齿匙形、提琴形等四种叶形来说，其误差较大，这些类型的叶片宜以多段的贝氏曲线进行几何模拟，以准确地逼近实际的叶片形状。

贝兹曲线 Bézier curve
（重定向自Bezier curves）
在数学的数值分析领域中，贝兹曲线（英语：Bézier curve）是电脑图形学中相当重要的参数曲线。更高维度的广泛化贝兹曲线就称作贝兹曲面，其中贝兹三角是一种特殊的实例。
贝兹曲线于1962年，由法国工程师皮埃尔·贝兹（Pierre Bézier）所广泛发表，他运用贝兹曲线来为汽车的主体进行设计。贝兹曲线最初由Paul de Casteljau于1959年运用de Casteljau算法开发，以稳定数值的方法求出贝兹曲线。

A Bézier curve is a parametric curve frequently used in computer graphics and related fields. Generalizations of Bézier curves to higher dimensions are called Bézier surfaces, of which the Bézier triangle is a special case.
In vector graphics, Bézier curves are used to model smooth curves that can be scaled indefinitely. "Paths", as they are commonly referred to in image manipulation programs, are combinations of linked Bézier curves. Paths are not bound by the limits of rasterized images and are intuitive to modify.
