Why Stop at Flat Screens?

Writing for Nautilus, Amos Zeeberg explains how a technique called projection mapping or spatial augmented reality is being used to project moving images not onto the flat screens familiar from movie theaters but onto buildings.

And curvy buildings, at that. A company called Obscura Digital projects video onto distinctive structures like the Sydney Opera House and the Guggenheim Museum.

The tricky part, of course, is figuring out how to warp the digital art to be projected so that when it is projected on the complicated shapes of the chosen building's architecture, it will be warped back to its intended appearance.
