摘要
本文用Bezier方法讨论平面及空间物体的保积逼近问题,给出三种算法.算法一适用于平面物体保面积;算法工及三适用于空间物体保体积.前二种算法通过分式线性变换,只需一元二次方程,最后给出计算实例.
This paper deals with volume-preserving approximation of planar and spatialobjects by Beezier methods.Three algorithms are discussed.The first algorithm applies topreserving the area of planar object.The second and third ones preserve the volumes ofspatial objects. Finally,some numerical results are presented.
