qft-variations-perturb.mjs — sketch 08.
|
|
New mechanics — fields perturbed BY their own physics:
|
|
|
|
WAVEPACKETS — Gaussian local perturbation of the cubic
|
|
(and schlegel) lattice; vertices push radially outward
|
|
under a bell-curve falloff. The "particle" is now a
|
|
feature OF the field, not a separate object placed on it.
|
|
|
|
RIPPLES — concentric expanding wavefronts from a source
|
|
point. Each ring a many-segmented polyline; renderer
|
|
applies propagator decoration to each chord.
|
|
|
|
Plus DENSER cubic (cubicN=2 → 125 vertices / ~300 edges) so
|
|
more grid lines show the wavepacket distortion clearly.
|
|
Output → output/qft/sketch08/
