The lesson is everyone attempting to enter the competition should have
rendered a submission quality image each weekend, from the start of the
contest until now. Then if you can't render your best version, you can
submit the second best.

Frequent releases also teach how long a render takes.

This is a "best practice" in software engineering.

Yeah yeah yeah, but the real world is messy.  I did a lot of due 
diligence full blown testing myself, along with clever speed testing, 
and built a lot into my code to facilitate that,... but I still got a 
big surprise during the final push at the end.  I, myself, was forced to 
enter a set of renders that I did in just the spirit you describe.  But 
they look embarassing to me now. They could have been improved 
dramatically with just a few "plan B" tweaks, once it was obvious that a 
technique I was depending on wouldn't work, but instead I had to watch, 
helplessly, as the clock ticked down, just as John did.

That's a nice invitation.  After all, one of the main attractions is the 
increased level of exposure, as much as the prizes.

have you tried a ram checker (memtest86)?
i found out (the hard way) that foulty ram only shows up in large renders.
(i got errors like "triangle misspelled" in the midle of a large (auto
generated) file with thowsands of triangles.. (and hang-ups :-) )

jaap.

I just barely managed to submit my entry in time.  I am by no means a
professional raytracer, but I had to challenge myself to get somewhere.
Just as I finished several hours of rendering, I noticed that one of the
meshes was missing from the foreground.  It was too late to go back and
replace it, and the scene was still intelligible without it.  I promised
myself I'd enter no matter how crappy my submission was.  At least now I
have a *very remote* understanding of some of what goes on underneath the
program's hood.  I think it would be really nice to have some interactive
graphical interface or preview option so I don't waste three hours
rendering the whole scene just to detect a simple problem in one little
corner.
Anyway, I'm sorry you couldn't finish yours in time.  I can't say my chances
are any better having submitted an entry than not, though.

Actually, I *was* doing that.  What I wasn't doing was the 2 'detail' 
images, as I had been doing close ups of the detail shots in other renders, 
so I didn't need to preview those.  The net result is that I was well aware 
of how long a render took, but the backup image wouldn't have met the 
requirements.

As I noted in the original, due to a versioning mismatch, the photon times 
suddenly shut up dramatically the last day, but that's an integration issue. 
Like all integration issues, proper planning from the start would have 
corrected that, so of course it's my screwup.  *so* much went wrong at the 
end there was only so much I could do.  Of course, I could have done better.

  The image is part of a series for a book I'm writing so it will live 
again, however.

  Right.  I've signed checks (authorized funds) for 16 million for software 
projects.  (no kidding).  You?  :)

Thank you (Chris).  Let me see if I can pin down the fog bug, rerender, and 
then I'll try and post something.

I agree about the exposure - this image in particular shows some interesting 
'code' things - I have a city that's built programatically, although 
distance shots show it a bit better.  The ability to easily extend POV Ray 
with SDL is IMHO one of the big attractions, compared to other programs.
