Wave-length of the ring spacing. Picks the LOD.
Peak vertical displacement at the center.
Radial extent — Gaussian envelope decays to ≈ 5% here.
OptionalspeedPropagation speed of the rings (world units per second). Default: deep-water dispersion velocity √(g·k)/k = √(g·λ / 2π).
OptionalphaseConstant phase offset (radians). Useful to de-correlate multiple ripples at the same location.
OptionalsteepnessLateral chop, [0, 1]. 0 = pure vertical; 1 = aggressive radial chop.
World XZ center of the ripple.
