摘要
B样条曲线曲面的降阶是样条曲线和曲面造型中的关键技术之一,为了实现不同CAD系统之间的数据交换,常用到这一技术,它已成为热点问题,得到越来越多的研究。结合作者在该领域的研究成果,文章综述了近年来国内外专家学者关于B样条曲线曲面的降阶逼近研究的方法、理论成果及实际应用情况,并对各种不同的方法进行了分析比较。
Degree reduction of B-spline curves and surfaces is a key technology in curve and surface modeling and it is widely used to exchange data between different CAD systems. Therefore, degree reduction of B-spline curves and surfaces has been a research hotspot and drawn more and more attention. An overview on the methods, results and applications of degree reduction of B-spline curves and surfaces in recent years are given combined with the author＇s work in this field. Besides, the comparison for those methods is also described.
