box{<-1,-1,0><1,1,1> pigment{boxed}}
or
plane{z, 0 pigment{boxed}}
The pattern appears only once, centered at the origin.

It start at a value of 1 at the origin and drop to zero at the edge of 
box{-1,1}

You can use :
translate 1 // make it fit the warp span
  warp{repeat x*2}
  warp{repeat y*2}
  warp{repeat z*2}
translate -1 // take it back to it's otiginal location
to make it fill the space.
