一种双曲抛物面上样条曲线的等距曲线算法
An offset algorithm of spline on hyperbolic paraboloid
摘要
Abstract
In order to obtain the spatial offset curve for a spline in the hyperbolic paraboloid,an offset algorithm of spline on hyperbolic parabolid is presented.The principal normal vector of the hyperbolic paraboloid spline is solved to get its offset curve with its barycentric coordinate systerm.With the help of affine transformation and vector cross product,the normal vector of spline curve is calculated.Through Matlab software,the equidistant curve drawing is implemented,and the equi-distant line is spliced in the case of a given node.The results show that the method is fast and convenient in drawing offset curve of spline on hyperbolic paraboloid.关键词
