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}
...
?
