Room-Sized LED Egg Captures Amazing 3D Models Of People Inside It
Google researchers have designed a prismatic light-emitting-diode (LED) "egg," to generate remarkable three-dimensional (3D) and relightable models of people within it. The egg uses volumetric capture, in which multiple cameras in a 360-degree arrangement render a photorealistic representation of a subject in motion, while also allowing the model to be realistically illuminated by virtual light sources.
This enables the model's placement in any virtual environment where lighting can change. The egg contains 331 LED lights that can produce any hue, and that shift in a specific pattern during subject capture, creating a lighting-agnostic model. When placed in the virtual setting, the models reflect the setting's lighting, and not the lighting of the egg itself.
