If the join points are modeled to be the same, there shouldn't be any
visible gaps between the polygons. However, it could be that they will be
there in some modeling/viewing apps. And, even in your "X" and "+" exaples,
noise might be apparent with specular shading enabled. If you point me to a
dat, I'll see if I can demonstrate it; I may not be able to, though.
