Class: WaterSpectrum
Defined in: src/components/renderer/WaterSpectrum.ts:10
Wind-driven ocean waves for WaterRenderer.spectrum: a JONSWAP spectrum, spread around the wind direction, simulated with FFTs in three cascades from swells hundreds of metres long down to centimetre ripples. Adds to the Gerstner waves.

WaterSpectrum
Properties
windSpeed
windSpeed:
number=10
Defined in: src/components/renderer/WaterSpectrum.ts:12
Wind speed 10 m above the water, in metres per second.
windDirection
windDirection:
Vector2
Defined in: src/components/renderer/WaterSpectrum.ts:14
Direction the wind blows toward, in the xz plane.
fetch
fetch:
number=100000
Defined in: src/components/renderer/WaterSpectrum.ts:19
Distance in metres the wind has blown over open water. A short fetch gives young, short waves; a long one, a fully developed sea.
amplitude
amplitude:
number=1
Defined in: src/components/renderer/WaterSpectrum.ts:21
Wave height scale.
choppiness
choppiness:
number=1
Defined in: src/components/renderer/WaterSpectrum.ts:26
How far the water moves sideways toward the crests: 0 gives rounded waves, 1 sharp crests and troughs that whitecaps break from.
seed
seed:
number=1
Defined in: src/components/renderer/WaterSpectrum.ts:28
Random seed of the wave phases.
