双三次调和Bézier曲面间的连续性条件

his paper mainly studies the relationship between control points when the two correspongding bicubic harmonic Bézier surfaces are C1 continuous. The results show that when the two bicubic harmonic Bézier surfaces are C1 continuous at the common boundary, the two bicubic harmonic Bézier surface patches are from the same piece of surface. Moreover, when the Cr continuity condition are satified at the common boundary for the two bicubic harmonic Bézier surfaces, it implys that the two bicubic harmonic Bézier surface patches are also derived from the same piece of surface.
