3D model z(x,y,t) ∝ [φₘₙ(x,y) + k·φₙₘ(x,y)] · sin(ωt) Površina je prava triangulirana WebGL mreža. Zvok uporablja izračunano resonančno frekvenco, 3D nihanje pa je namenoma prikazano upočasnjeno, da ga lahko vidiš. Pesek se v poenostavljeni simulaciji premika po gradientu vibracijske energije proti nodalnim območjem.

What am I observing?

A Chladni pattern visualizes standing waves. The m and n values define the mode; mixing them creates a more complex related pattern.
