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.
