It sounds like they place probes on a static regular grid, and if they collide with the SDF scene, the probe moves out of solid space by following the distance gradient. But it seems they do this at runtime, maybe to react on dynamic objects. Imagine a moving wall.

WebJul 2, 2024 · SDF is a scalar field in the space domain, which represents the distance from a point in space to the nearest surface in the scene. A positive value is assigned if the point is in the outer region of the nearest surface and negative if it is inside. In this way, it produces a compact representation of the geometry information of a scene.
