Twisted rippling wavy bands with scanlines
A picture built in steps: twist, then ripple the space, then draw wavy bands, then color it, then finish with scanlines. 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 488 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 = 6.0 * (1.0 - smoothstep(0.0, 0.55, length(p))); turn p by that angle- Step 2: Ripple the space
p.x += 0.07 * sin(p.y * 7.0 + time * 3.0)- Step 3: Pattern
m = 0.5 + 0.5 * sin(p.x * 8.0 + sin(p.y * 4.0) * 3.0)- Step 4: Colors
0.5 + 0.5 * cos(6.28318 * (m * 1.3 + float3(0.3, 0.2, 0.2)))- Step 5: Finish
col *= 0.8 + 0.2 * step(0.5, frac(uv.y * 100.0))
