First: Watch your language.

Second: Here's some documentation for you to read:

http://www.povray.org/documentation/view/3.6.1/300/
http://www.povray.org/documentation/view/3.6.1/73/
http://www.povray.org/documentation/view/3.6.1/157/
http://www.povray.org/documentation/view/3.6.1/531/

Third: A modified version of your your code that renders ok:

// ===== 1 ======= 2 ======= 3 ======= 4 ======= 5 ======= 6 ======= 7

#version 3.6;

#include "colors.inc"
#include "functions.inc"

// ===== 1 ======= 2 ======= 3 ======= 4 ======= 5 ======= 6 ======= 7
// The isosurface object. Note that less noise is added.

isosurface {
   function {
     f_sphere(x, y, z, 1.2) - 0.5*f_noise3d(x, y, z)
   }
   contained_by { sphere { <0, 0, 0>, 3 } }
   pigment { color White }
}

// ===== 1 ======= 2 ======= 3 ======= 4 ======= 5 ======= 6 ======= 7

light_source { <1, 1, -1>*100 color White }

camera {
   location -5*z
   look_at 0*y
}

background { color Blue*0.5 }

// ===== 1 ======= 2 ======= 3 ======= 4 ======= 5 ======= 6 ======= 7
