Rippling 5×5 tiled zigzag stripes with a dark vignette
A picture built in steps: ripple the space, then tile, then draw zigzag stripes, then color it, then finish with a dark vignette. 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 419 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: Ripple the space
p.x += 0.05 * sin(p.y * 11.0 + time * 2.0)- Step 2: Tile
p = frac(p * 5.0 + 0.5) - 0.5 (repeat the picture 5 times across)- Step 3: Pattern
m = step(0.5, frac((p.y + abs(frac(p.x * 3.0) - 0.5) * 0.6) * 6.0))- Step 4: Colors
lerp(float3(0.06, 0.11, 0.17), float3(0.43, 0.59, 0.84), m)- Step 5: Finish
col *= 1.0 - 0.65 * smoothstep(0.3, 0.85, length(s)), s = (uv - 0.5) * float2(aspect, 1.0)
