92 Gears - Animation Study

By TaffGoch
29 Favourites
Feasibility study, for potential photo-realistic rendering

• Red gears: 20 teeth, 12 count
• Blue gears: 24 teeth, 20 count
• Yellow gears: 13 teeth, 60 count

Red gears aligned with icosahedron vertices • Blue gears aligned with dodecahedron vertices

Polyhedral basis for red & blue gears: buckyball

Regarding all 92 gears, the central rotation axes are aligned with the vertices of a frequency 3v, class-I geodesic tessellation of an icosahedron

Modeled in SketchUp • Animated in JASC Animation Shop

Minor edit (28 July 2011): Adjusted GIF dither, to reduce obvious color "banding," and added internal "geodesic cage" support frame

See stereo version, 92 Gears - Animation Stereo3D

Rendered version; work-in-progress, so far: 92 Gears - Caged

Dear TaffGoch,

Your gear graphics are very impressive. Is it possible to purchase a license from you for just a still, grayscale image? I might only need a grayscale image of one of them.

Thank you very much.

Have a nice day.
Best regards,

You may use an image, without license, under the condition that attribution is provided.

The numbers 21 and 13 are surprising to me.

And so are the counts 20 for blue and 12 for red. At first glance I would expect the reds to have a multiple of 5 and the blues to have a multiple of 6.

Quite right, Hollister, :doh:

I revised the model, but failed to revise the metrics in the text description. I have, today, corrected that oversight.

The red (pentagonal/dodecahedral center) gear tooth-count is, indeed, a multiple of 5, and the blue (triangular/icosahedral center) tooth-count is divisible by 3.

Getting the yellow gear tooth-count correct was a matter of trial & error, by resizing the red & blue gear diameters. I had to "sneek up" on a reasonable solution.

awesomely psychadelic. :D

how long did this take!
TaffGoch's avatar
About a day.

(Actually, just about all of a day! I'd have to say ~15 hrs.)

Excellent. I'm out of word.

This is too AWESOME!!!

Can you do the same animation in cross-eyed stereo? :please:

Don, see cross-eyed stereo version: 92 Gears - Animation Stereo3D

Outstanding!! :wow::clap:

I just took today to revamp the gears, to more equally-space the yellow gears.

Next, I'll give a stereo version a try. (It's been awhile since I've done one, and never with SketchUp, but all the tools I need are there.)

That's cool! You should check if it's 3D printable :D But then all the gears somehow would have to be connected to a center...

If you look closely, you'll see that I've amended the model; providing an internal frame that secures the 92 axial shafts

I've used Shapeways to 3D-print a couple of models, but it's still way too expensive.

Maybe, when the price becomes more-reasonable....

Wow, sir, this is awesome, can't wait for the P-R render!
