Pixelated twisted wave lattice
A picture built in steps: pixelate, then twist, then draw wave lattice, 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 517 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: Twist
angle = 2.5 * (1.0 - smoothstep(0.0, 0.6, length(p))); turn p by that angle- Step 3: Pattern
m = smoothstep(-0.25, 0.25, sin(p.x * 21.0) * sin(p.y * 21.0))- Step 4: Colors
lerp(lerp(float3(0.12, 0.06, 0.09), float3(0.93, 0.35, 0.52), smoothstep(0.0, 0.5, m)), float3(0.44, 0.94, 0.91), smoothstep(0.5, 1.0, m))
