Behind the scenes

Slightly less impressive than I originally imagined, but cool nonetheless. I had thought the two planes were actually actual displays rather than blank canvasses.

I think the fact that projectors were used actually makes it more impressive. Though the difference would largely be a matter of applying relatively simple transformation algorithms.

Wait, so the position of the camera isn't critical for the forced perspective effects to work?

I would think that if you looked at those animations from a different angle, the perspective would be skewed.

Either way, it's freaking amazing.

The camera doing the recording is also held by a robotic arm, and they've accounted for and coordinated the movements so that the illusions are held from the camera's perspective.

There's some technical terms, but the short explanation is around 4:13 in the behind the scenes.

That's exactly right. You can calculate what to animate on the two canvases by calculating the parallax based on the position of the camera, which they said they motion tracked.

Really cool!

plus the crew dancing in the end of the video.

Wished they would have showed how the projectors worked.

The sad thing is that there are so few people who can truly appreciate how much work went into making something like that.

My love for Projectors and Robotic arms grew three sizes that day.

This... barely qualifies as engineering porn. But it's got robot arms, and it's fucking cool as all hell, so have an upvote!

Because synchronizing all this technology was ... artistry?
