摘要: 样条曲线曲面在CAD和计算机图形学领域起着重要作用. 本文提出了三次均匀B样条的几类扩展形式. 基于新的样条函数和奇异混合技术, 提出了插值 α-B样条的几类新扩展. 所提出的新样条曲线的优势是他们同时具有全局形状参数和局部形状参数. 最后进一步探讨了它们在数据点插值和多边形形状变形中的应用.Abstract: Spline curve and surface play an important role in CAD and computer graphics. In this paper, we propose several extensions of cubic uniform B-spline. Then, we present the extensions of interpolating α-B-spline based on the new B-splines and the singular blending technique. The advantage of the extensions is that they have global and local shape parameters. Furthermore, we also investigate their applications in data interpolation and polygonal shape deformation.
