Pixelated bulging wave lattice with a fade to dark at the bottom
A picture built in steps: pixelate, then bulge, then draw wave lattice, 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 365 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: Pixelate
p = (floor(p * 10.0) + 0.5) / 10.0 (snap the position to a grid of 10 blocks per unit)- Step 2: Bulge
p *= 1.0 + 1.5 * dot(p, p)- Step 3: Pattern
m = smoothstep(-0.25, 0.25, sin(p.x * 14.0) * sin(p.y * 14.0))- Step 4: Colors
lerp(float3(0.91, 0.97, 0.96), lerp(float3(0.1, 0.71, 0.9), float3(0.78, 0.09, 0.38), uv.y), m)- Step 5: Finish
col *= 0.5 + 0.5 * uv.y
