Twisted 5×5 tiled wavy bands with a pulsing brightness
A picture built in steps: twist, then tile, then draw wavy bands, then color it, then finish with a pulsing brightness. Every step is listed below with its exact numbers.
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 463 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)- Step 1: Twist
angle = 4.5 * (1.0 - smoothstep(0.0, 0.55, length(p))); turn p by that angle- Step 2: Tile
p = frac(p * 5.0 + 0.5) - 0.5 (repeat the picture 5 times across)- Step 3: Pattern
m = 0.5 + 0.5 * sin(p.x * 10.0 + sin(p.y * 9.0) * 3.0)- Step 4: Colors
lerp(float3(0.18, 0.09, 0.12), float3(0.84, 0.46, 0.4), m)- Step 5: Finish
col *= 0.85 + 0.15 * sin(time * 3.0)
