Since I'm new to both, its hard to destinguish. Im trying to experiment 
with media by placing a smoke-filled glob inside water.

#declare Media =
media {
	emission 0.05
	intervals 1
	samples 5
	method 3
}
difference {
box {<-4,-1,-1><4,1,1>
      material {water}
     }
isosurface {
         function { f_sphere(x, y, z, 1.2) + f_noise3d(x+X, y+Y, z+Z) }
         contained_by {sphere {< 0, 0, 0>, 1}}
       	interior { media { Media } }
             }
hollow
}

I dont see anything... My guess is that I cant set up proper parameters, 
or I defined the CSG setup wrong for media.
Any help greatly apprecited.
