Click the pool to drop a stone. Each drop launches a circular wavefront whose height is h = amp·sin(kr − ωt), with k = 2π/λ and ω = k·v. Amplitude decays with distance (geometric spreading) and time (Damping). Overlapping wavefronts sum — superposition — producing bright and dark interference fringes, the same physics as the 3D version's GLSL shader, evaluated here on a coarse grid and rendered as a 2D heightfield map.

About this 2D version

A flat, top-down companion to the 3D GLSL water-ripple shader: the same wave equation — circular wavefronts, geometric and time decay, and linear superposition of up to 12 simultaneous sources — drives a coarse heightfield grid rendered directly with Canvas 2D instead of a lit 3D mesh.
