摘要
提出了一种基于能量法的截面曲线自动形状修改算法．这种算法在保证截面曲线整体能量最小的基础上，对截面曲线所有节点同时进行调整．实践表明，本算法不仅能较迅速地消除因数据点误差带来的截面曲线不光顺现象，提高曲面的光顺性；而且能通过控制截面曲线节点的调整量，达到控制曲面修改量的目的．
An algorithm for automatic modification of
sectional curve is presented based on energy minimization. Every node of the sectional curve can
be modified simultaneously, and the total energy of the curve minimized. Using this algorithm, not
only the smoothness of the surface can be improved by eliminating the deviation of the data of the
sectional curves, but also the range of the modification of the points of the sectional curve can be
controlled. This algorithm has been successfully used in a NC oriented free surface design
system.
