surfacesofrevolution0引言近年来,细分曲面造型方法成为计算机辅助几何设计和计算机图形学中的一个主要造型工具,其优势在于细分方法可从任意形状网格出发构造光滑曲面,而无需考虑几何连通性问题.细分算法按照细分规则在细分过程中是否改变,可以分为静态细分和动态细分2种.Doo—Sabin细分算法LlJ是一种经典的静态细分算法,它所...

New methods for evaluation of values and derivatives of Doo-Sabin surfaces at arbitrary parameters by means of non-iterative approaches are presented. Furthermore, generalized basis functions for non-uniform Doo-Sabin surfaces are derived. Thus, many algorithms and analysis techniques developed for ...
