NURBS曲面造型中曲线曲面分割问题研究
Study on Curve and Surface Trimming Problem inNURBS Surface Construction
【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。
【Abstract】 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.
