So, I finally got enough round-tuits saved up to forge ahead and rewrite my
prototype involute gear "drawing" scene (which also wrote an SVG file for
laser-cutting) so that I could make proper 3D gears.
I'll likely have to create several variants depending on the given data, but it
seems to work reasonably well at the moment.
I still need to work out a good texture with (micro)normals to mimic machining
marks, and get some marking on the vertical sides of the prism teeth.
Maybe some additional alternatives to spokes.
One step closer to the Antikythera mechanism.

If you're working on the Antikythera mechanism, you'll definitely appreciate
this guy's work:

(who happen to have nice 3d rendering too, but probably not using POV...)

Yes - I've already binge-watched all of his videos on that :D

Wow, you're gonna create the Antikythera in povray? That's an amazing piece of
hardware. Looking forward to that.
Good luck.
Cheers
Ton.

This is coming from the guy who's building the Titanic with the same software.

Hey, I figure that after the solar system and 65,000 minor planets, what's 37
gears of varying module - pieced together from the x-rays of the barely intact
oxide crust of the recovered half? *
It's curious that I can't find <x, y, z> data for the centers of the gears so as
to properly locate them.

You as well - keep at it.
*So, The Thoughts (TM) went storming through my head last night and this
morning, and
1. 2000 years later, that thing was still there
2. What was found was lying on the ocean floor, right up at the surface
3. someone just found it by accident, incidental to being nearly shipwrecked
4. Jacques Cousteau himself brings his team to bear on the site in 1976 to
collect its relics **
5. All this activity reveals that the merchant vessel was HUGE and loaded beyond
capacity
6. Wright disregards the pin-and-slot gear assembly
7. Freeth discards the 53-tooth count
8. Only after an 8-ton custom x-ray machine is all but given away - and
delivered - to scan the artifact fragments is there any idea what this thing
really is
9. Fragment F, overlooked, and almost forgotten gets scanned and provides some
of the last clues that help put everything together.
10. Imaging expert Tom Maltzbender applies his PTM image processing, allowing
the inscriptions to instantly be almost magically readable
11. There seems to me to be an inexplicably WIDE range of interpretations as to
how this was put together, and what the output dials looked like. This is
incongruous with having X-ray slices of all the recovered mechanism fragments
Which leads me to conclude:
It aint over yet, folks.
There's still more to be seen in, and learned from the pieces we've got.
Using further image-processing algorithms like FFT, edge-detection, and a
version of PTM that uses the X-ray data, I'll bet there's more to be found in
the extant X-ray slice data
There are more pieces of the device to be recovered at the site.
Use a metal detector!
Just look how much was unrecognized, overlooked, discounted, almost discarded,
and uninvestigated.
Which leads to the big one: If it's being likened to a laptop with the data of
the cosmos programmed into it through gearing, and Chris of ClickSpring asserts
that a jig was likely used due to the need for the fast _repetetive layout of
gears_ ( https://www.youtube.com/watch?v=BIUAdINXZmQ ), then it's highly likely
that somewhere in the ship's cargo hold, in the unexplored deeper regions of the
wreckage site...
THERE'S ANOTHER BACKUP COPY OF THE DEVICE
Intact, crated, [relatively] undamaged, and protected from oxidation.
And it needs to be recovered.
** no mention of this expedition on the wikipedia page :O
