# FFT ocean surface

> A displaced ocean surface driven by a real inverse FFT. A Phillips spectrum evolves in frequency space, two compute passes run a shared-memory radix-2 IFFT into a displacement field, and a procedural grid rides it with per-pixel normals, foam and a Fresnel sky reflection under a tunable sunset. Orbit with the mouse; tweak the sea from the panel.
