Every particle moves at the same speed and adopts the average heading of its neighbours within r, plus a random twist of size η.
Drag the noise η. Tap to scramble a region. The same ?seed= always gives the same run.
LITThe Vicsek model (1995). Every heading must stay finite and the order parameter φ must stay in [0, 1], or the page throws.
AMBERDifferent from the Zero Flock: no cohesion and no separation, only alignment and noise.
