1. Define a function{pigment{PATTERN turbulence FOO}}
2. Define a function{pigment{function}} based on 1 with a color map which sets
up a nonlinear relationship.
3. Declare a pigment{function}} based on 1, inserting whatever colors you like.
4. Declare an isosurface with function {y-function2} and pigment from 3.

Oh well, I'll just give away the kernel here:


#declare feestruct=
function{
    pigment{
        function{rawfee(x,y,z).grey}
        color_map{
            [0        color rgb 0.0]
            [sandline color rgb 0.0]
            [treeline color rgb 0.1]
            [1        color rgb 1]
            }

    }
}
