摘要
给出了一种基于三角函数的类三次参数曲线,该曲线不仅具有类似于三次Bézier曲线的诸多性质,而且无需有理形式即可精确地表示椭圆、抛物线等二次曲线.
A class of quasi-cubic parametric curve based on trigonometric functions is presented. The curve has a lot of similar characteristics with cubic Bézie curve. Furthermore, it can represent the elliptic curves, parabola and other quadratic curves without using rational form.
