Hi, all, following is a very simple scene, why the image is not so smooth,
have any ideas?
/////////////////////////////////////////////////////////
  camera {
    location <0, 2, -3>
    look_at  <0, 1,  2>
  }
  sphere {
    <0, 1, 2>, 2
    texture {
      pigment { color rgb<1,1,0> }
    }
  }
  light_source { <2, 4, -3> color rgb<1,1,1>}

Only two possibilities I can think of. Either you are not using antialiasing
or your monitor isn't set to 24-bit color or higher. If it is a unsmooth
edge line then the answer is to turn on AA (antialiasing), if it's color
banding on the surface of the sphere then it's color depth.

I wouldn't think it's a POV-Ray image display or file output thing unless
you aren't using the defaults.
