三角域和四角域上Bernstein-Bezier曲面片的拼接

GC^1 continuity condition between adjacent rectangular and triangular Bernstein-Bezier patch

给出了具有公共边的三角域和四角域上Bernstein-Bezier曲面片光滑拼接的条件,该过程不需提高曲面的次数,有效地解决了构型复杂、形状和边界不规则的几何造型问题.

The geometric continuity condition is presented so that the adjacent rectangular and triangular Bernstein-Bezier patches can be joined together smoothly, which needn't raise the surfaces degree.
