🥁 2D Drum Membrane — Circular Wave & Bessel Modes (2D)

A real-time top-down 2D simulation of a vibrating circular drum membrane. Watch Bessel-function eigenmodes (m,n) form Chladni nodal patterns, click to strike, and tune damping and wave speed.

⚙ Under the hood

Watch a circular drum membrane vibrate in real time from directly above, colour-mapped by displacement. Select angular (m) and radial (n) Bessel eigenmodes, click anywhere to strike the membrane, and tune wave speed and damping to see Chladni nodal patterns form and decay.
