摘要
根据3次NURBS曲面的矩阵表达式,通过反求NURBS曲面的权因子和控制顶点,完成了对3次空间NURBS曲面的插值;并在此基础上,结合蒙面法构造了空间2×3次NURBS曲面;最后利用MATLAB软件对曲面进行了生成,验证了该算法的准确性和可行性。
Based on the matrix expression of NURBS-face, the interpolation of cubic space NURBS-face is completed by reversing weights and control points of cubic NURBS-face. Then based on that, the 2×3 cubic NURBS-face was constructed by skinning method. In the end, the NURBS-face was generated by using MATLAB, the accuracy and feasibility of the algorithm were proved.
