See the posted code for both algorithms in p.b.s-f. ...

No, it isn't... as your superellipsoids don't intersect anywhere, unlike in my
scene, where always one out of eight cubes is
hidden inside the cube of the previous iteration! But on the other hand, even
when I programmed an exeption for this one
cube (i. e. not to render it at all), I still got this mean "Too many nested
objects" when trying to render more than four
iterations deep!

I also programmed a scene with spheres who did not intersect at all - and then
it was no problem to render, let's say five
iterations...

You clearly ran me out... this cries for revenge!

See you in Khyberspace!
