bevy-aqua-waves

Wave production for Aqua's AnimWaves cascades: the analytic Crest Gerstner component bands and the spectral Tessendorf path (JONSWAP h0 via bevy-aqua-fft, Stockham transform, phase evolution, resolve, cascade combine).

Owns

  • generate_components + spectrum_amplitude: the stratified Crest spectrum (deterministic, seed 0).
  • The FFT pipeline glue: h0 texture creation from bevy_aqua_fft::make_h0, field textures, attenuation-bin gating, per-frame uniforms.
  • Compute shaders (embedded): anim_waves*.wgsl, fft_evolve/resolve/ surface.wgsl, and the surface module displace.wgsl published at import path aqua::waves::displace.
  • Frame + render-world Prepared (the live AnimWaves uniform, shared with the query pass through bevy_aqua_core::AnimWavesUniform).

Public API

AquaWavesPlugin, plus the umbrella-facing helpers displacement_bounds, DisplacementBounds, StartupAmplitude, RenderPrepared, and the startup/update systems. Settings live on bevy_aqua_core::OceanWaves.

Test alone

cd crates/bevy-aqua-waves && cargo test

Isolation example: cargo run --example waves-only (core + waves on a flat ocean).
