Projection mapping is the art of using physical objects as display surfaces and turning them into something else visually. This video of Box is an impressive demonstration of the technology.
"Box" explores the synthesis of real and digital space through projection-mapping on moving surfaces. The short film documents a live performance, captured entirely in camera. Bot & Dolly produced this work to serve as both an artistic statement and technical demonstration. It is the culmination of multiple technologies, including large scale robotics, projection mapping, and software engineering. We believe this methodology has tremendous potential to radically transform theatrical presentations, and define new genres of expression.
I would've thought this was CGI if I didn't know any better.
