How it works

This is a top-down light-field map of the same esca physics as the 3D version, rendered natively in 2D: instead of a rendered lure mesh, every grid cell of the water column is its own numerical sample of the Beer-Lambert field, colour-coded by intensity — so the glow you see is the actual field, not a lit surface.

I₀ = I_max · dⁿ / (dⁿ + Kⁿ)     (Hill function, n = 4)
I(r) = I₀ · e^(−k·r)
R = ln(I₀ / I_th) / k

The small inset graph plots the Hill quorum-sensing curve itself with a live marker — a view the 3D scene has no room to show. Prey are 2D dots that wander until the flashing esca's field crosses their contrast threshold at their own position, then home straight in.

Bacterial density — moves the marker across the Hill curve, switching I₀ on/off nonlinearly.
Turbidity — sets k; watch the field visibly shrink or bloom outward as it changes.
Flashing lure mode — the field itself pulses on/off across the whole grid in sync with the shutter.
