摘要
研究了在曲线形状保持不变的条件下,空间有理三次Bézier曲线权因子改变与曲线参数化的关系。同时,给出了空间有理三次Bézier曲线上点的参数与权因子之间的对应关系。
This paper discusses the relationship between the variation of weights for rational cubic space Bézier curve and parametrization of curve with the shape unchanged. The correspondence relationship between the parameter of a point on a rational cubic space Bézier curve and its weights is given, and the parametric transformation formula is derived which has the same influence on parametrization as the weight changed.
