摘要
本文将双圆弧形逼近平面曲线拓广成逼近空间曲线 ,得到给定空间R3 中的两点及其单位矢量的双圆弧形式 ,并给出双圆弧逼近空间曲线时的误差估计 ,在数控加工及船体放样中有一定的实用价值。
This paper is about the generalization of approximation spline estended in plane to space.The biarc spline is generated through two given points and two given vectors in R3,and the estimation of error is given about the approximation of curve in space with biarc spline.The result is useful in numerical-control and mathematical ship lofting.
