摘要

提出了一种新的具有两个形状参数的有理二次三角bsamizier曲线。目的曲线具有传统有理二次曲线的所有几何性质。通过改变曲线的形状参数和权值，可以实现对曲线形状的局部控制。该曲线精确地表示椭圆的圆弧和圆的圆弧等二次三角曲线，最接近普通有理二次bsamzier曲线。

The Rational Quadratic Trigonometric Bézier Curve with Two Shape Parameters

In this paper, a newly constructed rational quadratic trigonometric Bézier curve with two shape parameters is presented. The purposed curve enjoys all the geometric properties of the traditional rational quadratic Bézier curve. The local control on the shape of the curve can be attained by altering the values of the shape parameters as well as the weight. The curve exactly represents some quadratic trigonometric curves such as the arc of an ellipse and the arc of a circle and best approximates the ordinary rational quadratic Bézier curve.
