控制多边形 meaning in Chinese
control polygon
Examples
- We find out the ball basis of the space kn and define the h - ball curves with this ball basis
由这组基通过控制多边形定义的曲线即是空间k _ n中的ball曲线 - By changing the value of the shape parameter , we can adjust the approaching degree of the curves to their control polygon
通过改变局部形状参数的取值，可以调整曲线接近其控制多边形的程度。 - This paper present a sufficient and necessary condition of constructing quintic ph curves and analyze the geometric meaning of the control polygon
本文给出了构成五次ph曲线的充要条件，分析了其控制多边形的几何意义。 - The main innovation of our method is that we only need construct polygonal mesh possessing simple symmetric properties on both sides of control polygon edges of interpolated curves , and do n ' t need modify the subdivision rules near the interpolation curves during the process of subdivision . thus the subdivision rules are simple . the process is convergent and the limit surface is c everywhere except a finite number of points
该方法的主要创新思想是，在被插值曲线的控制多边形两侧构造具有简单对称性质的多边形网格，而在细分过程中，则无须修改被插值曲线附近的细分规则，凶此细分算法是简单的，细分过程是收敛的，且最终的插值曲面除有限个点外是c ~ 2连续的。 - Its accomplishment is simple and intuitional . the main innovation of this method is that we only need construct a symmetric zonal mesh for each interpolated curve respectively and write appropriate knot spacings for mesh edges . then applying nurcc rules to the initial control polygonal mesh consisting of those symmetric zonal meshes can generate a surface that satisfies interpolation constrains
该方法的主要创新思想是在被插值曲线的控制多边形两侧构造具有简单对称性质的四边形网格，称为对称网格带，但关键还在于对网格边赋予适当的节点距，并对由这些对称网格带组成的初始控制网格应用非均匀有理catmull一clark细分规则，来生成满足插值要求的曲面
