摘要
对于给定的曲线型值点及端点切向量，本文利用二次ＮＵＲＢＳ曲线的矩阵表达式，给出了一个反求二次ＮＵＲＢＳ曲线控制顶点的算法，并且证明了所求控制顶点的存在唯一性。
For given points and top tangent conditions of a curve,an interpolation algorithm of quadric NURBS curves is presented by using the matrix representation of quadric NURBS curves and the uniqueness of control verttcs solved inversely by the algorithm has been proved.
