Phonon-like oscillation with a periodic amplitude wave. Drag to orbit.
A 3D mass-spring style lattice of atoms is rendered with cylindrical bonds. Each atom jitters sinusoidally per-axis while a Gaussian-enveloped amplitude wave sweeps along the x-axis, mimicking a traveling phonon packet.
Lattice atoms: 216 (6x6x6)
Bonds: 540
Atom spacing: 1.6
Base amplitude: 0.05
Wave amplitude: 0.22
