Gerstner wave ocean surface
In your harnessGodot shaderMIT
Displace a subdivided plane with three summed Gerstner waves computed in world space, with analytic normals, sharp crests, crest foam colour and a view-dependent deep to shallow tint.
What it takes and gives
- Shader type
- spatial
- Parameters
- deep_color (vec4 = 0.02, 0.1, 0.18, 1), shallow_color (vec4 = 0.06, 0.38, 0.45, 1), crest_color (vec4 = 0.8, 0.92, 0.95, 1), amplitude (float = 0.22), wavelength (float = 3.5), steepness (float = 0.65), speed (float = 1), direction_degrees (float = 25) and 2 more
- Use it on
- A subdivided PlaneMesh (or other flat grid); the demo uses 120 x 120 subdivisions.
- Result
- A rolling sea with sharp crests, light foam on top and sun glints.
- Renderers
- compatibility: compiled and rendered, forward plus: not verified, mobile: not verified
- Placement
- res://baltor/godot_shaders/gerstner_wave_water/
Limits. The plane must be dense enough for the shortest wave or the shape aliases. No transparency, refraction or depth fade (see toon_water_foam for depth-based shading). The CPU does not know the wave height, so floating objects need the same formula in a script.
