摘要
研究在曲线形状保持不变的条件下，空间有理三次Ｂｅｚｉｅｒ曲线权因子改变与曲线重新参数化的关系。给出了空间有理三次Ｂｅｚｉｅｒ曲线上点的参数与权因子之间的对应关系，并导出权因子改变对空间有理三次Ｂｅｚｉｅｒ曲线参数化有影响的参数变换公式。
f A relationship between weights for rational cubic space Bezier curve and shapeunchanged is discussed. A correspondence relationship between the parameter of point on a rational cubicspace Bezier curve and its weights is given, and the parametric transformation formula is derived whichhas a same influence on parametrization as a weight changed.
