摘要
提出一种基于ＮＵＲＢＳ齐次坐标表示来计算曲线曲面分割问题的方法，把ＮＵＲＢＳ问题转化为四维空间里非有理Ｂ样条问题，就可利用Ｂ样条分割算法来解决，其几何意义明确，求解过程简便易行，便于在ＣＡＤ／ＣＡＭ系统中实现。
Based on the NURBS homogeneouscoordinate expression,the authors put forward acurve and surface trimming algorithm. By transforming NURBS problems to non-rational B-splineproblems,the trimming algorithm of B-spline canbe utilized.This method has explicit geometrymeaning and convenient calculating procedure,thuscan be easily used in CAD/CAM systems.
