Spinning wave lattice
A picture built in steps: spin, 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 435 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: Spin
turn p by time * 0.6 radians: c = cos(angle), s = sin(angle), p = float2(c * p.x + s * p.y, -s * p.x + c * p.y)- Step 2: Pattern
m = smoothstep(-0.25, 0.25, sin(p.x * 14.0) * sin(p.y * 14.0))- Step 3: Colors
lerp(lerp(float3(0.12, 0.21, 0.11), float3(0.6, 0.86, 0.48), smoothstep(0.0, 0.5, m)), float3(0.48, 0.57, 0.86), smoothstep(0.5, 1.0, m))
