多网络。任意参数矩形上具有特征性质的离散光滑曲面的分类
Multi-Nets. Classification of discrete and smooth surfaces with characteristic properties on arbitrary parameter rectangles
摘要:
我们研究了各种光滑和离散网的常见基本离散结构。其主要思想是将网络的特性不仅施加在基本四边形上,而且施加在较大的参数矩形上。对于离散的平面四边形网、圆形网、$Q^*$ -网和圆锥形网,我们得到了相应的离散多重网的一个特征。在极限情况下,这些离散网导致一些经典类的光滑曲面。此外,我们建议使用的特征离散网作为离散扩展的网络,以获得结构保持细分计划。
英文摘要:
We investigate the common underlying discrete structures for various smooth and discrete nets. The main idea is to impose the characteristic properties of the nets not only on elementary quadrilaterals but also on larger parameter rectangles. For discrete planar quadrilateral nets, circular nets, $Q^*$-nets and conical nets we obtain a characterization of the corresponding discrete multi-nets. In the limit these discrete nets lead to some classical classes of smooth surfaces. Furthermore, we propose to use the characterized discrete nets as discrete extensions for the nets to obtain structure preserving subdivision schemes.
