OK, here's the code to my post "Weird media efect" in p.b.i. I see
nothing wrong in the code but the result is highly aliased (please see
the image). Before I write a bug report I want to make sure this is
not how Monte Carlo media sampling is supposed to work and it's just
me that can't use it.

#declare i=-50;
#while (i<=50)
  cylinder 
  { 0, 50*y, 4.9995 
    pigment { rgbf 1 }

    interior
    {
      media
      {
        scattering { 1, 0.2 } }
        ratio 0.5 + 0.5*(i+50)/100
        intervals 30
        samples 3, 10
        confidence 0.9999
        variance 1/255
      }
    }
    
    translate x*i

  }
  
  #declare i=i+10;
#end

camera

  location <0, 25,-300>
  direction 300*z
  right 110*x
  up 50*y
  look_at 25*y
//  orthographic    // the aliasing gets even worse with it
}

// end code
