Back in January we shared this post and picture of Ender’s Game actor, Khylin Rhambo. At the time he stated via Facebook, that “the technology in the picture was used to scan his face, take costume measurements, ‘and other stuff.’”

Thanks to Darian‘s investigative work, we’re getting better picture of what this technogolgy actually does.

The technology is called Light Stage X. The spherical network of lights is used to digitalize “people’s faces to turn a real person in to a digital person that would be just as realistic as the real thing,” says one of its creators and lab directors Paul Debevec, Ph.d.

Watch the video below for a better understanding of how the cast will be digitalized for the battle room sequences.
