【摘要】 细分曲面造型技术是一种基于样条可细化性质基础上的以网格细分为特征的离散造型方法,具有表示的任意拓扑性,光滑保证性,计算简单性等传统方法难以比拟的优点。本文介绍了常用几种细分方法的细分规则及其应用。如Loop细分法、蝴蝶改进法、Cat-mull Clark法和Doo-Sabin法。更多还原

【Abstract】 Subdivides the surface modeling technology is one kind may in the thinnature foundation subdivide based on the transect take the grid as thecharacteristic separate modelling method,has the expression the freeanalysis situs,smooth guarantee,traditional method hard to compareand so on computation simplicity merit.This article introduced thecommonly used several kinds subdivide the method to subdivide the ruleand its the application.If Loop subdivides the law,the butterflyimprovement law,Catmull the Clark law and the Doo-Sabin law.更多还原
