6×6 tiled rippling zigzag stripes with a fade to dark at the bottom
A picture built in steps: tile, then ripple the space, then draw zigzag stripes, then color it, then finish with a fade to dark at the bottom. 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 384 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: Tile
p = frac(p * 6.0 + 0.5) - 0.5 (repeat the picture 6 times across)- Step 2: Ripple the space
p.x += 0.03 * sin(p.y * 11.0 + time * 2.5)- Step 3: Pattern
m = step(0.5, frac((p.y + abs(frac(p.x * 3.0) - 0.5) * 0.5) * 7.0))- Step 4: Colors
lerp(float3(0.95, 0.92, 0.94), lerp(float3(0.73, 0.21, 0.65), float3(0.3, 0.79, 0.27), uv.y), m)- Step 5: Finish
col *= 0.65 + 0.35 * uv.y
