I started a different explanation but I think I have an easier way
of explaining it so you might understand what I am trying to say.

If you are familiar with the Pov-Ray mesh object then you know that
it is made of just a few to several tens of thousand of triangles
depending on how many were generated by the program that made the
original. Hfs object in Pov are treated internaly the same as the
basic mesh object is.

  If you use a very small image to make your Hf object then there are
only so many triangles available in the image file to reconstruct the
model from. If your originaly generated file is large enough, I like
to use from 500x500 up to 800x680 size, It will have many, many,
times more data available for the program to work with. This means
it can use 12000x more triangles in the same space you are using with
the smaller image and this gives better control over the surface
faceting of the HF object. You can't build a smooth sphere with 8
flat plates but if you had a few thousand flat plates to work with
you could smooth it out enough that no one wouild notice it except
when viewed under highly magnified viewing conditions.

Nothing comes to mind right now but if it does I will let you know.
