Scrolling rippling grid with a pulsing brightness
A picture built in steps: scroll, then ripple the space, then draw grid, 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 332 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 * 0.25- Step 2: Ripple the space
p.x += 0.08 * sin(p.y * 9.0)- Step 3: Pattern
e = abs(frac(p * 9.0) - 0.5); m = step(0.42, max(e.x, e.y)) (lines on the cell borders)- Step 4: Colors
lerp(float3(0.42, 0.84, 0.36), float3(0.53, 0.39, 0.85), m)- Step 5: Finish
col *= 0.85 + 0.15 * sin(time * 3.0)
