Ocean Waves — 2D Cross-Section

This side-on view uses the exact Gerstner (trochoidal) wave equations behind the 3D ocean simulation, sliced along the direction of travel. Up to three superposed wave components sum their horizontal and vertical displacements to build a realistic swell profile with sharp crests and broad troughs, while a grid of subsurface markers traces the circular particle orbits that shrink with depth — the real mechanism behind wave motion, not a simple sine curve. Push the Steepness slider up to see the trochoid approach — and eventually overturn past — the physical breaking limit.
