摘要
针对参数样条曲面变形或近似展开时变形或近似展开前后点的对应关系的确定问题，提出了一种算法：根据参数样条曲面与其参数平面上点的一一对应关系，用参数平面将变形或近似展开前后的曲面联系起来，通过由坐标反解参数和由参数正解坐标，建立起其上点的对应关系。
An algorithm is proposed for determining the mapping relation between points on the former parametric spline surface and the other one which is changed from the former one, and by means of the same parameter, the relation between points on two parametric spline surfaces is founded.
