摘要
讨论了一类具有形状参数的二次三角多项式曲线。该类曲线具有与二次B样条曲线样的良好性质,其特点是C1连续,且可精确表示椭圆、抛物线等圆锥曲线弧。
In this paper a class of quadratic trigoncmetric polynomial curves with a shape parameter is discussed. The curves have good properties analogous to the quadratic 3-spline curves. The class of quadratic trigonometric cueves can represent ellipse and parabola.
