四次C-Bézier曲线的形状修改
Shape modification for quartic C-Bézier curves
摘要
Abstract
Based on the analysis of the the quartic C-Bézier basis function, this paper puts forward two methods about the control shape of the quartic C-Bézier, the modify control parameterαand modify control vertex that control parameters on the role of the shape, and puts forward the control parameters adjustment methods of modification curve shape. On the other hand, based on the relations of control points and the curve shape, it establishes the algorithm of adjustment control vertex. Finally, the paper puts forward some specific numerical experiments. The modeling examples show that the method in computer aided geometric design has certain application value.关键词
