单调曲率在具有美学形状的曲线设计中起着重要作用。本文分析了贝塞尔曲线的曲率分布,发现如果满足三个条件,则贝塞尔曲线的曲率是单调的。我们还给出了单调曲率贝塞尔曲线的充分几何条件。此外,我们提出了一种单调曲率变化(MCV)贝塞尔曲线的设计方法。实验表明,新方法构造的曲线不仅形状美观,而且曲率分布单调。
Monotone curvature plays an important role on curve design with aesthetic shapes. In this paper, we analyze the curvature distributions of Bézier curves and show that if three conditions are satisfied, then the curvature of the Bézier curve is monotone. We also give a sufficient geometric condition of Bézier curves with monotone curvature. Furthermore, we present a designing approach of monotone curvature variation (MCV) Bézier curves. Experiments show that curves constructed by the new method perform well not only in terms of aesthetically pleasing shape, but also in monotone curvature distribution.
