The HoloLens headset mixes reality with impressive and sometimes lifelike holograms that users can interact with. To capture dynamic actions in such great detail, Microsoft created a huge TV studio in Redmond, WA. The space is outfitted with a large calibrated green screen and 106 synchronized RGB and infrared cameras. All of these cameras take in information at various angles and compile it together so that they can create realistic three-dimensional models and spaces. And unlike the process that was required to capture the performance of Gollum in Lord of the Rings, no special green screen suit is required by the performer.
