Too hot to photo today...

Instead I thought I'd put together a video of my 3D rig in action and some of the outputs. There is even an app that controls all the rig function but also calculates all of the 3D geometry for you as well, warning you to possible issues like motion blur and speed limits on the buggy.

Overall, I'm particularly proud of my contraption, now I just need a way to make some money from it, 3D family portrait anyone? :)

Anyhow, enough jibber jabber, here is the video. You will need red/blue 3d glasses to see the anaglyphs later in the video.

3D rig - the final cut

Ok, so I have finished all of the tweaks to the buggy and about ready to combine all of the notes into a version 2. So how does version 1 compare up to my original list of requirements? Well, it does pretty well actually.

There is a capacity problem in that the rig won't carry my heaviest gear because of a severe centre of gravity issue. The tripod head also caused some issues because of the weight being higher up, but also because the adjustment bars interfered with the power switch.

If you watch the video below, you'll notice a fair bit of "jitter" as the camera pans, this seems to be because of 2 things:

3D D-brief

After finishing my rig at 7:30 on Friday night with limited testing it was packed up and shipped to be used in its first test run Saturday morning... All-in-all not a bad first go, I did manage to get a couple of passable 3D shots from it, but it needs some tweaks...

1. Rotation motor slips - turns out to be a loose bolt holding the spindle to the camera plate.
2. Camera plate wobbles - turns out a bit of paper will fix it, but redesigned the top panel to only use 3 bearings, there is a reason tripods only have 3 legs, and it's not because of the name.
3. Jerky movement - software fix required to accelerate and decelerate slower.

So, that's this weekend's mini-project, and then some still life examples. For example a redo of this one.
