    摘要:

    本文给出在空间三角网格上用三角Be’zier曲面构造G1插值所需的最低次数,并给出五次G1插值的具体构造方法.

    Abstract:

    This paper proved that the lowest degree of GI interpolation over 3D triangulation with Be'zier triangular surface patches where only one patch is constructed over one triangle region is quintic and a scheme of constructing lowest degree of GI interpolation over 3D triangulation is described in detail.
