Hasan,
Looking at your image, I think that the sphere needs a couple of 
subdivisions more. Have you tried that, by applying smooth a couple of 
times?

Thomas, right, more subdivision solve this problem, but it creates extra
unnecessery vertex points. is there another way?

Well, in addition, there might be the problem mentioned by zorglub and 
Florian. Have a look at the mentioned documentation.

  No, that's not it. The correct url is:

How about replacing the mesh with

    sphere{0, 1}

In all seriousness, POVRay SDL is extremely powerful and renders MUCH faster 
than meshes!
