论文摘要
S点具有许多不错的数学属性。自从他们首次出现以来就知道了任何常规的S-Patch都可以精确地转换为修剪的有理Bézier表面。与其他多边表面表示相比，这是一个很大的优势，这些表面表示必须近似以将其导出到CAD/CAM系统中。然而，实际的转换过程仍处于理论层面，其中零件散布在多个出版物中。在本文中，我们回顾了整个算法，并从实际方面进行了调查。
S-patches have many nice mathematical properties. It is known since their first appearance, that any regular S-patch can be exactly converted into a trimmed rational Bézier surface. This is a big advantage compared to other multi-sided surface representations that have to be approximated for exporting them into CAD/CAM systems. The actual conversion process, however, remained at a theoretical level, with bits and pieces scattered in multiple publications. In this paper we review the entirety of the algorithm, and investigate it from a practical aspect.
