We observe that the relations for the geometric continuity of surfaces are very similar to the ones for the geometric continuity of curves. But as a shape parameters there are matrixes W ij instead of real numbers. In the beginning we require geometric continuity of the first order of the patches F and G along the common boundary t 1 t 2 . Let's continue by investigating the geometric continuity of the second degree of two Bezier patches. Let's look at it more closely.
Conclusion Let's look at the result.
