    根据移动一个控制顶点而固定其他控制顶点的方法,分析一种类四次三角样条曲线的形状.在一类控制多边形下,利用控制顶点之间距离的关系,分别得到了对应的四次三角样条曲线含有尖点、二重点以及拐点的判别条件.

    By varying a control point and fixing the rest, the shapes of a class of quasi quartic trigonometric spline curve lying to a kind of control polygons are studied. The discriminate conditions of cups, loops and inflection points are obtained according to the distance of the control points respectively.
