I thought it might be easy to just give both hole A and hole B the same number of vertices per curve (19), and then make edge loops that connect each vertex from hole A, to its corresponding vertex from hole B.
But if you look at the bottom of the pic you can see the problem, if I connect the first vertex of hole A to the first vertex of hole B, the line cuts through the hole itself, and if I continued connecting some of the lines would cross each other.
What’s a smart way to make this into quads? Also if I keep it as simple as possible it seems like I’d have some really long thin quads, is that a problem?
PS: if it matters my eventual goal is to use smooth shading (not subsurf, for simplicity). It’s ok if all the edges, even the sharp ones, are a bit rounded.
