| 摘 要： | 根据Ｂ样条曲线原理，提出了先用若干个截平面去切割几何物体，得到一组与几何物体轮廓线相交的点。根据这些点，再用Ｂ样条曲线去构造几何物体的近似轮廓线，从而得到几何物体模型。该方法方便、精确，便于在计算机几何造型系统中应用。

| Abstract: | According to the principle of B spline curves,a method of cutting the geometric objects by cross sections is put forward to obtain a lot of points with which an approximation contour of objects is formed.And the model of geometric objects is constructed.This method is convenient and flexible in the system of constructing geometric objects model by computer. |
