    Translate what? The isosurface function?

   // make a pigment into a function
 #declare CR = function{ pigment { crackle scale 0.5 } }


surface{ 
      function { 
                // make a sphere
                 (x^2+y^2+z^2)
                // add the crackle
                +(CR(x, y, z)
                // make it half as deep
                *0.5)
               }
