Plasma

Recreate the animated plasma.

Play this challenge All challenges

The target picture for the shader challenge "Plasma" — 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 284 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

Space: p = (uv - 0.5) * float2(aspect, 1.0) * 8.0
v: sin(p.x + time) + sin(p.y*1.3 + time*0.7) + sin((p.x+p.y)*0.8 + time*1.3) + sin(length(p) + time)
Color: 0.5 + 0.5 * cos(v * 1.5 + float3(0.0, 2.0, 4.0))

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.
