带双参数四次Said-Ball曲线的扩展
Extension of quartic Said-Ball curve with two parameters
摘要
Abstract
In order to make the curve easy to achieve smooth connection ,and at the same time has different shapes corresponding to the same control points ,a kind of new curve w hich has convex hull property ,symmetry ,shape adjustability is defined .The properties of the blending functions and curves ,and the geometrical property of two shape parameters are analyzed .The G0‐continuity ,G1‐continuity and G2‐continuity conditions of two pieces of curves are also given . Similarly ,the continuous composite surface with local shape adjustability is constructed .The numerical examples illustrate the correctness and effectiveness of the modeling method .关键词
