三角网格细分模式的统一框架研究

Study of the Unified Framework for Triangular Subdivision Schemes

通常情况下,三角网格细分模式由面分裂的初始模式和点分裂的对偶模式构成。本文为这两种不同的模式提出了一个统一的框架,定义了复合细分操作,并对当前流行的几种模式进行了分析。在此框架基础上,三角网格细分模式得以扩展。

Generally, triangular subdivision schemes consist of the primal schemes which split faces and the dual schemes which split vertices. This paper proposeda unified framework for the two distinct schemes, defined the composite subdivision operation, and also analyzed some popular schemes. Based on the framework, the kinds of the triangular subdivision schemes were extended.
