常用的cad设计中之所以选用3次B样条而不用更高次是因为次数越高,控制点影响的曲线段数就越多,不利于局部控制;而三次Bezier曲线意味着必须有4个控制顶点.他们的区别主要有以下4点:1、Bezier曲线的基函数次数等于控制顶点数减1.B样条曲线基函数次数与控制顶点数无关;2、Bezier曲线的基函数是Beinstein基函数,它是个...

The binary subdivision of the uniform B-spline curves and surfaces motivate much of the work on sub- division curves and surfaces – where the word “subdivision” here is taken from the process that is used to subdivide a curve or surface into multiple components. In the uniform B-spline ...
