Is it just me or does anyone else notice that the edges of that corner surface has a minute aberrations, or a 'rumply' appearance?

I always thought it would seem like a viable solution to use multiple three or four-sided surfaces matched together to provide the solution to such a complex area.

Wouldn't forcing the sides and corners of a surface to be stretched like some leather skin or screen mesh would yield inaccuracies.

I could be wrong, but to me it seems logical to use two three-sided surfaces matched together at some median seam to get a patch that would meet at six-sides like in this example.
