Projection Mapping in Motion Amazes

Projection mapping is pretty magical; done well, it’s absolutely miraculous when the facade of a building starts popping out abstract geometric objects, or crumbles in front of our very eyes. “Dynamic projection mapping onto deforming non-rigid surface” takes it to the next level. (Watch the video below.)

A group in the Ishikawa Watanabe lab at the University of Tokyo has a technique where they cover the target with a number of dots in an ink that is only visible in the infra-red. A high-speed (1000 FPS!) camera and some very fast image processing then work out not only how the surface is deforming, but which surface it is. This enables them to swap out pieces of paper and get the projections onto them in real time.

Make sure that you do watch the video. The bit where they aim a fan at the projection-mapped T-shirt, and the dancing animated Stanford Bunny flaps in the breeze along with it is truly amazing.

Want more of the projection-mapping craze of the early 2010’s? Check out this post on projection mapping with industrial robot arms, or a projection mapped sandbox.  If that’s not enough for you, have a look at this footage from [Amon Tobin]’s live tour in 2012.

Thanks [Stuart] for the tip!
