Actually, the bumps pigment in an isosurface looks more like what I want than
the noise3d.  With nose3d, I got some pretty neat structures by adding
polynomials to it, which looked like landscapes.

Is there a way to do mathematical operations on pigments?

I've tried with failure:
    function { y- pigment {bumps}}
Should I instead  I do:
    function {y}- function{pigment {bumps}}
Or:
    #declare yikes= function{pigment {bumps}};
    isosurface {
        function {y-yikes}

...

?
