Easy Patterns
Tilted hexagon outline with a border
A picture built in steps: tilt, then draw hexagon outline, then color it, then finish with a border. 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 526 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: Tilt
turn p by 1.0 radians: c = cos(1.0), s = sin(1.0), p = float2(c * p.x + s * p.y, -s * p.x + c * p.y)- Step 2: Pattern
d = max(abs(p.y), abs(p.x) * 0.866 + abs(p.y) * 0.5) - 0.24; m = 1.0 - smoothstep(0.012, 0.02, abs(d))- Step 3: Colors
lerp(float3(0.08, 0.11, 0.17), float3(0.42, 0.48, 0.92), m)- Step 4: Finish
edge = min(min(uv.x, 1.0 - uv.x), min(uv.y, 1.0 - uv.y)); col = lerp(float3(0.72, 0.4, 0.93), col, smoothstep(0.05, 0.056, edge))
