You declared your pigment as:
#declare ObjectFunc =
function {
    pigment {boxed
        color_map {[0 rgb 1][0 rgb 0][1 rgb 0]}
    }
}

What are you expecting this color_map to result in? It starts out as 
white, but goes to black in 0 distance and ends in black, basically a 
black pigment...isosurfaces require a smoothly varying function. My 
guess is you want either this:
color_map {[0 rgb 1][1 rgb 0]}
or something similar to this:
color_map {[0 rgb 1][0.5 rgb 0][1 rgb 0]}
