3ill links phones in one location so each camera contributes its perspective of a physical scene. A central aggregator fuses them into a navigable 3D world you fly a virtual camera through, like a video game whose level is built live from everyone's phones. The system maps coverage from all poses, exposes blind spots, and guides phones to positions where the fewest cameras cover the most scene.
