Water ripples

Concentric ripples that travel outward and fade with distance.

Play this challenge All challenges

The target picture for the shader challenge "Water ripples" — Recreate this picture. You pass at a 99% match, then try to write it in fewer characters than the par.

How this challenge works

You write a fragment shader that draws the picture above, live in your browser. A match bar shows how close you are, and the score combines accuracy, code size (the par is 236 characters in Unity (Built-in)) and GPU speed. Work in HLSL, GLSL, WGSL, Metal or Godot and export the result when you are done.

The numbers you need

Wave: sin(d * 40.0 - time * 6.0) * exp(-d * 3.0)
Deep: float3(0.02, 0.2, 0.4)
Crest: float3(0.4, 0.85, 0.95)
Mix: w * 0.5 + 0.5

Solve it in your language

Unity (Built-in), Unity (URP), Unreal, Shadertoy / WebGL, OpenGL (LWJGL, raylib), three.js, GameMaker, LÖVE (Lua), Godot, Apple (iOS, macOS), WebGPU / Bevy.
