Just wondering how the container for the isosurface examples in the docs was
pigmented / textured separately from the isosurface proper.
http://www.povray.org/documentation/view/3.6.1/73/
"For making it clearer what surfaces are the actual isosurface and what are
caused by the container object, the color will be different in all the following
pictures."
The method used is not explained, nor have I (so far) been able to come up with
a syntax that the parser accepts.

A basic trick would be along:
intersection {isosurface {
function { ... }
contained_by { box { -2, 2 } }
evaluate 4, 1.18, .7
all_intersections
texture { pigment { color red 1 } }
}
box { -1, 1 scale 1.5 texture { pigment { color blue 1 } } }
}

Yes, I guess I just thought that there was a way to do that directly by
texturing the contained_by box, rather than through CSG.
Thanks for the tip :)
