Week TechVideo, 2008 #11 - 8660 raytrace animation

If you liked the 'Amazing LEGO TECHNIC raytraced images' post a few months ago, take a look on the video below from the 8660 (Artic Rescue Unit).
A must see and an amazing CG LEGO TECHNIC animation!

Don't know exactly how it was done or which tools were used, but from the author's comments at YouTube it looks like the animation was not done manually, i.e. rotating the moving parts one by one in small steps, to achieve the final animation effect, as I initially thought.
Somehow it seems the tool used, was able to propagate the movement across the gears and into other parts!???
"...I think it is properly rigged to work mechanically. For example, when you set the angle of the top steering wheel all the connected gears are calculated and turn appropriately and end up turning the wheels' steering."

One way or another, it took about 22 days to render the overall video in POV-Ray...
From the above, I guess it was not used in conjunction with the remaining LDraw tools suite.

I'm not sure this answer your question, but you should investigate this way :

Maybe, something like this!?

I've tried 'SR 3D Builder' before, since Sergio advertised it in the forum of my LUG, but didn't realize on the capability to rotate gears and hinges, at the time.

It's really great, however I must invest a lot more time on this SW, as I can't get used to the user interface :(, neither to get rid of some problems...

I also knew about SR 3D Builder, from the same forum, and thought the only advanced modeling it could do was beam alignment to form triangles... I never imagined it could do this kind of "automatic gear rotating"!

I'm more used to MLCad's interface; just like Michael Lachmann has added support in his app for other people's utilities, he and Sergio could work something out to bring the best of both worlds.

But it can do it! ;)

It's amazing.
I must post a video of it working sometime ahead...

Incredible work! I wish my animations on Technicopedia looked this good. However, if I had to spend 22 days on each one it would take me a very long time indeed!

I believe your animations are harder to do, since you have to manually reposition the set for each frame, and using a physical model... with weight and balance issues.

try my latest releases of SR 3D Builder.
Graphics quality is not the same, but mechanics are the same and it's in real time without to have to do nothing but build
