Scrolling rippling zigzag stripes
A picture built in steps: scroll, then ripple the space, then draw zigzag stripes, then color it. 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 297 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: Scroll
p.y += time * 0.15- Step 2: Ripple the space
p.x += 0.06 * sin(p.y * 10.0)- Step 3: Pattern
m = step(0.5, frac((p.y + abs(frac(p.x * 4.0) - 0.5) * 0.5) * 10.0))- Step 4: Colors
lerp(float3(0.18, 0.07, 0.15), float3(0.82, 0.34, 0.63), m)
