A chess set is not as classic as the reflective sphere on a checkered
plane, but it comes close. Thus I decided to make one myself.
  I made it completely from the scratch, all by hand and pure CSG (I have
played chess quite a lot and I know what the pieces look like, approximately
at least).

  Making a chess set is actually quite fun. I recommend it to everyone
who hasn't done one yet.
  It's not too difficult (the horse is the piece that requires most work,
as can see in my image as well).
  The set forms a very nice hierarcy of objects. In my set the base of each
piece is the same object; then I made colorless versions of each piece on
the base object, and then white and black versions of each piece. Then I
just copied the right number of pieces to the board.
  It's also easy to make a little macro that positions a piece on the board
given its coordinates. This way it's easy to actually "move" the pieces
on the board, as in actual playing.

what would be really cool is a macro that could translate from shorthand 
chess notation to create a full on animation of an entire game. Add a 
swooping camera, and some notation from famous games (deep blue vs issac 
asimov)  and you got yourself a pretty cool pov script there.

  That shouldn't be too hard.

  I don't think a moving camera is a good idea in this kind of very long
animation unless you have hundreds of megabytes of free disk space :)

I really like this.  I'm not thrilled with the marble texture though, too
sharp and the lines are so continuous I think is why.  Those reflections
going into sharp focus due to the different camera to object distances is a
neat effect (or reality?).

Depending on how long it takes to render I think you could make a chess game
out of this that povers could play.

I think the objects are nice but the focal-blur are overdriven and
annoys me.

Apart from that, let me use this chance to remind everyone to BACKUP
their files regulary as I just lost all my POV-work due to a harddisk
crash.

very nice - as with bob, think the marble needs work - maybe cracks

Warp:
That is a beautiful chess set. Very nice job on the Knight, which is of
course
the most challenging piece. I don't like the focal blur however, it is too
much.
You wouldn't get that much focal blur with a real camera unless you had a
bad lens with wide open aperture. From a purely aesthetic point it is too
noticeable and detracts from the image. Maybe you could just reduce it a
little.

It depends on how quickly the camera moves.  In my IRTC anims, the
camera is often moved slowly (say 1 to 3 cm per second), just to keep
otherwise-still shots interesting.  It does boost the files size, but
not by very much.

John
