(I had to resend the file, because I received some error. I hope it won't
come as a duplicate)

This is my latest creation, some screws tossed on a wooden table.

The wooden texture was taken from some place on the web.

It took about 3 hours in my P4-1.8Ghz

I attempted to make it as photorealistic as possible, I hope you like it.
Any comments and/or suggestions will be appreciated.

Fernando.

It's very nice! Depth of field, finish of screws. I have 3 small
suggestions:

1)  Blur the reflections on the wood.
2)  Translate seam of texture away from origin (or make it seamless)
3)  Concentrate the screws in a smaller area and crop resolution.
     (For those of us, who doesn't have so big screens.)

But I got to say, it's very, very nice!  I also wonder:  If the shadows are
so intense, why don't I sense an intense lightsource above the scene .. the
screws are very reflective so I would expect a strong highlight. But maybe
you have referenced a photo so I shouldn't complain?  :o)  (not that I try
to complain at all)

Regards,
Hugo

I swear, if you put a slight scratch on the table somewhere, I'll
accuse you of posting a photo.

Very nice...

About the blurry reflection, I tried adding a layer of transparent and
reflective "varnish"... however, the results were not that impressive, and
the render time was awfully increased. Do you know of a better way of doing
it?

About the seam, I was going to do it, but I forgot :P

About the placement, I totally agree, but as the screws are located
randomly, some intersections may occur, and I had to disperse them more to
avoid that, without having to place them individually... Yes, I admit I'm a
bit lazy, he he he

Excellent. This was well worth downloading twice! Would you mind sharing
your AA settings?

Fernando,

How do you position the screw objects on the table? In particular, I'd like
to know how you rotate the screws so that they lie so nicely without
clipping through the table's surface, or leaving small gaps where contact
should be made.

Do you manually estimate the transformations until it looks right, or do you
have an algorithm that uses trace() to figure it out?

I'm trying to work on an algorithm that lets me place objects onto a surface
in a natural way.

Thanks Shay!

Of course, my antialias settings are none :) I used focal blur instead:

  aperture 0.5
  blur_samples 64
  confidence 0.9

I rotated the screw by trial and error, until I believed it looked OK :)

Then I copied them and distributed them randomly, and had to use trial and
error to avoid intersections between screws...

Not very elegant, but it was faster than coding something more complicated.

Fernando.
