The latest iteration of this technology takes the illusion even further, adding a three-dimensional light mapping element to make the projection seem like a real 3D object reflecting light.

Projection mapping is frequently used by visual artists and during concerts or product demos, but it's interesting to see how precise the technology has become in smaller scale experiments.

We’ve seen many, many, many times before how projection mapping can be used to create mind-blowing optical illusions. But what happens when you add 3-D glasses to the mix?

It’s the work of San Francisco studio Bot & Dolly, which believes its new technology can “tear down the fourth wall” in the theater. “Through large-scale robotics, projection mapping and ...
