Code Snippet:

#if( use_df3_proximity_pattern )

   average
   pigment_map {
#if( blur_proximity_pattern = false )
    [ 0.5 df3_pattern ]
#else
 #declare n = 0;
 #while ( n < 60 )
     [ 0.5 df3_pattern translate (halton3D( n )-<0.5,0.5,0.5>)*7.5 ]
  #declare n = n + 1;
 #end
#end

#if( add_noise = true )
    [ 0.1 slope { y altitude <0,1,0> } color_map { [0 rgb 1] [1 rgb 0] } scale
