Motion Control and 3D

Published : 18th June 2011

Has anyone had any experience with this?

I know that the Flying Wombats have made an indexer for stop motion but as far as putting a
full 3d rig on a Motion Control rig is there anything I should look out for?

Hi Justin,

Coraline was entirely made with one eye on motioncontrol rig and still cameras.

Here goes one link :

We had single camera motion control tools added to the Kuper motion control software back at Digital Domain during Terminator 2 - 3D.

I was the operator.

It's been a part of the Kuper software ever since. You can contact Joe Lewis at General Lift in El Segundo, CA

Just tech'd a few days worth of minis and full size MoCo using an older DD system and the latest generation 3ality rigs (with digital linear encoders). Took a little bit to calibrate Kuper to the rig but once it was done, worked great, very repeatable. 3ality uses Preston HW for front end of control (with custom SW and protocol adapters) but team MoCo team already had the Kuper to Preston cables so it was pretty straight forward.

Hi Chris ..

This should be a private email but I'm going to keep it public just in case anyone else is interested (or comes up with this in the future ....

In his setup you had a single camera but on a slider such as this ..
http://www.dragonstopmotion.com/iota.php and used for stop motion or in realtime but with only moco elements moving ..

I'm trying to work out what would be needed to run a rig in real time (zoom and focus obviously so we would need preston adapters) and perhaps a channel for interocular distance (assuming it would move). But unless I'm missing something .. not alot more ..

What would the assembled company WANT on a moco rig for 3D?

Hello Justin,

As you say, I would want to control focus (and eventually zoom, and more rarely iris) for each eye and also control a motorized IA setting.

Eventually a convergence motor as well, but that need is less frequent as far as I am concerned. We would also need to frame sync both eyes and the rig software together.

Best regards!,

Kommer.

For us we had a very standard motion control rig setup and large miniature setting. Single camera, no 3d rig or anything extra. The move was programmed for composition of one eye and the needed photographic passes then shot. The move was then offset, via software controls for the other eye, to the desired parameters and then passes were shot again.

To my knowledge, from some of the compositors, it worked well - bumps from hardware needed smoothing, but that happens with motion control sometimes.

That's the simplified view.

Justin! You're a mind reader!

I was just about to contact you about a job that is MoCo and involved Focus, Zoom, IO and Convergence all under MC control.

Probably a Quasar rig with RED's and 15-40 Optimo's.
