Just a note on the artifacts. Playing around with other radiosity settings,
(and even looking more closely at this one), the landing gear on the plane are
just simple cylinders, but I can see radiosity artifacts on them, too. So, the
problem isn't limited to isosurfaces, although it is more prevalent there.
