摘要
对任意三角形,本文给出了在边界上已给定顶点型值向量、一阶切矢和二阶导矢的插值型的三角曲面片。这些曲面片可以组合成任意的复杂形状,且组合曲面是C2 的。
For arbitrary triangle,this paper has given triangular surface patches of interpolant,which interpolate the value of position,first order derivative and second order derivatives of the data at vertices on edges .These surface patches can combine arbitrary complex shapes,and these combining surface are as in the C 2 case.
