带形状参数的七阶均匀B样条

Uniform B spline with shape parameter of seven order

给出了带形状参数的七阶均匀B样条基函数,使七阶均匀B样条基函数是它的一个特例。由带形状参数的七阶均匀B样条基构成的B样条曲线可通过改变形状参数的取值而调整曲线的形状并且可以调整曲线接近其控制多边形的程度。

In The uniform B spline with shape parameter of seven order is given. The uniform B spline of seven order is its special example. The spline curves which are constructed by the uniform B spline with shape parameter of seven order basic functions can adjust the curve's shape and the approaching degree between the curve and its control polygon with changing the parameter value.
