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.
