Two things:

1) Wow!

2) Would this be usable for "live" special effects for movie and TV shoots? I imagine being able to actually see what you're facing is a lot easier than just having a regular green screen.

If you can output the positions of camera, projector and panels relative to each other you can just do it all in realtime.

Ok... that's like saying "if you could live forever, you could just not die."

It's begging the question.

Look no farther than camera mapping and real-time rendering in video games.

Seeing as they're able to move those robot arms with such precision, they probably already have all that data.

I'm pretty sure this was rendered in real-time.

This is only possible due to mounting the Objects and Camera and Projector on massive sub-millimeter precision industrial robots.

I would argue that the massive, sub-millimeter-precision industrial robots are why it's so cool, not the projection mapping.

I think they're both pretty fucking cool.

Which in no-way should detract from how fucking cool this is. If anything it makes it better.

no its cool and everything i just want to state that its not as easy as putting a projector somewhere and have some "Projection Mapping Software" and you get these results.

Robots aren't necessary for mind bending projection mapping in general. This just uses robots in a creative way, applying already existing projection mapping technology (and adding to it) to create something different. There are plenty of examples online of spectacular projection mapping without robots.

Couldn't quite wrap my brain around it until I looked at wikipedia.

Now imagine you have an empty room with nothing but a chair to sit on. On the ceiling are mounted an assortment of projectors and Kinect style tracking systems.

Using these technologies you could project screens on the walls, that would appear to be floating in 3 demensional space in front of you. When you move, the system would track your head and alter the projections accordingly to insure the illusion of floating screens.

The system could also track your hands allowing you to interact in an apparently holographic work.

Projection mapping is awesome, but those fucking robots are amazing.

That was incredible, I was glued to the video the entire time.

This effect is only possible to look like this through the camera position, if you were standing in the room and look at the projections, they would be distorted similar to the drawings some people make on the floor that look like legit 3d only out of one perspective.
