Sorry Steve I was indeed not clear in my question. As Chris said, I was
looking for an isosurface-function-operator.

CSG does not work, because the cutout-surface would not be affected by the
third function (in this case a wood-pattern as function). In this special
case I have now, I avoided the difference by "rebuilding" the inverted shape
(a simple box) with two unioned boxes (the contained_by-object cared for the
rest). But that was only possible in this simple case.

Thanks for the help,

Marc-Hendrik
