【摘要】 针对节点向量为端点插值、内部是单节点情形的2个双三次NURBS曲面,给出了它们之间的G1光滑拼接条件,得到它们的公共边界曲线所要满足的本征方程.其中本征方程是NURBS曲面片所独有的现象.更多还原

【Abstract】 The G~1 continuity constraints for two bicubic NURBS surfaces with clamped, uniform knot vectors along their common boundary curves are obtained. And the intrinsic conditions of the control points of the common boundary curves, in which the eigen equation is the special phenomenon of NURBS patches, are obtained as well.更多还原
