WebIn vector calculus, divergence is a vector operator that operates on a vector field, producing a scalar field giving the quantity of the vector field's source at each point. More technically, the divergence represents the volume density of the outward flux of a vector field from an infinitesimal volume around a given point..

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.
