A gyroid whose walls thicken with the distance from the centre: thickness = 0.13 · |p| millimetres.
The distance is the length of the position field, and a formula turns it into a thickness; the lattice reads that thickness at every point. Any field can drive a lattice the same way: a distance, a stress result, a measurement.
