基于分块矩阵求导的Bézier曲线降阶方法
Method for Degree Reduction of Bézier Curve Based on Partitioned Matrix Derivation
摘要
Abstract
The approximation of degree reduction to Bézier curve has its practical application value but is limited by constrained condition of endpoints.It comes up a new method for degree reduction approximation based on partitioned matrix derivation.This new method can produce explicit formula-tion with multi-degree reduction and satisfies constrained condition of endpoints.Finally combining mid-point segmentation with partitioned matrix’s derivation and putting them into numerical experi-ment show the advantages of this algorithm.关键词
