The Iso on it's own has nothing to do wth the marble. It's just that looking
through the translucent Iso shows the turbulated pattern on the plane as if
it's not turbulated. Checker or gradient y does not behave that way.

In addition, the container-object is visible in that it shows the
unturbulated marble, too, but in a blocky way.

The first problem is partly resolveable by a low accuracy and removing the
f3(x,y,z)*0-part. But even with very low settings, you don't get the "real"
turbulated marble-pattern, but something which seems to be sized down.
The second one (visible container) keeps poping up but with max_gradient
20000 and a smaler Container in the z-direction, it begins to show
someturbulence, too.

Yep, that's clear. I thought, I wrote something sufficient in my first post.
Obviously not. Hope this one is better. I, too, just try to find out what
happens.
