First stability test

Here are two separate passes we shot with our stability rig.  Our gear factor is an incredible 1:13824 and the motors take a couple of minutes to move .1 of a centimeter.  While that’s great, it’s a bit unwieldy, unless we get some higher power motors.  So we’ll be working with finding the sweet spot, where we can hit the same precision, but get our rig to move a bit quicker (click on the images for the movies).

This move is driven by processing and Maya.  We’re mostly just using Maya to set some simple moves and use it’s curve editors, until we get our own flavor of 3d interface up and running in processing.  The moves are exported as .move files, which then I parse through in processing and transfer to translation for the rig.

This test is to find out whether we can accurately repeat the same motion.  Below is the combination clip, where blue represents one layer, and red represents the other layer.  For the next few tests, I’ll shoot each pass with the same lighting conditions and do some difference composites (instead of this red/blue).

While the test is interesting, I’ve had to slightly hand transform (a few pixels) and then animate over the length of the shot one pass in order to match the other.  Our task will be to narrow down where this descrepancy is happening (either our rig, or the motors, or the software).

This test is only 25 frames, but we’ll get some longer length tests also up soon.
