⚙ Under the hood

A CPU finite-difference solver for the classical 2D wave equation, rendered with Canvas2D on a 160x100 grid. Click or drag to drop Gaussian ripples, drive a continuous point source, toggle reflecting or absorbing boundaries, and switch on a double-slit barrier to see interference fringes form. Live HUD readouts show the effective wave speed, damping coefficient, peak displacement and field energy each step.
