This paper defines the curve triangle and its internal diameter and external diameter.
定义了曲线三角形及曲线三角形的内径与外径,并给出了它的内径和外径公式。
The second chapter deals with a class of 3-degree continuous trigonometric curves with the shape parameter,the curve that interpolates start point and end point is analogous to Bézier curve,the larger isλ,the curve comes more near the control polygon,the elliptic and parabolic arcs can be represented exactly by the curve.
本文一共包含五章内容第一章,简单介绍了研究背景及主要研究内容;第二章提出了一种带参数的三次三角曲线,具有类似Bézier曲线的性质,插值于起点和末点,λ越大越接近控制多边形,利用此曲线能精确表示椭圆与抛物线弧。
This paper deals with the problem of trajectory synthesis using trigonometric curves,which are defined by sinusoidal functions and their harmonics.
这篇论文介绍如何使用三角曲线进行轨迹合成。
A kind of quadratic parametric trigonometric curve is presented on special quadratic trigonometric basis, which basis functions have two parameters.
给出了一种类似Bzier曲线的二次参数三角曲线,其基函数由一组带有两个参量的二次三角函数组成。
