I have never been able to figure out how to completely smoothly have
another number than four bicubic patches meet at a point. What rules did
you use to accomplish it?

It would be nice if you gave all the patches the same color, and maybe a
little phong or specular, so the smoothness can be better examined. From
the posted images, it's impossible to tell if the surface really is
completely smooth.
