What you're looking at. The real 3D-printer infills — the lattice your slicer
lays down inside a part — clipped to a ball and sliced. Scroll to peel the
layers from the top down; the orange face is the freshly cut cross-section.
Coarse FDTD: transmission loss of this orb vs free field, source at centre.
Solid is modelled as a dense fluid, so the solid shell, full enclosure and closed
cells (the dominant barriers) read true; fine open-cell pore absorption is below this grid —
that's the WebGPU job.
