Abstract

Abstract: According to the theory of Bezier surface，adopting in the public boundary the proposition of curve continuity and clipping plane，the joining between adjacent rational Bezier surface is studied；Meanwhile the G¹ continuity conditions of two double four degree adjacent rational Bezier surfaces are given，a lot of adjustable shape parameters are gotten thus.

Key words: rational Bezier surface, G¹ continuity, weight

摘要： 依据有理Bezier曲面理论，即采用在公共边界处曲线连续和切平面光滑连续的性质，研究了有理Bezier曲面的拼接问题，给出了具有公共边界曲线的两张双四次有理Bezier曲面G¹光滑拼接条件，从而得到很多的可调形状参数。

关键词: 有理Bezier曲面, G¹连续, 权因子
