seedmap

Generate canvas tiles using 2d noise from seed. Major/minor pass preserves primary detail quadrants cross-resolution.

usage

• seed -- Start value for recursive noise. Default is Math.random().
• size -- Size of canvas. Default is 64.
• count -- Total canvases. Default is 1.

import { seedmap } from "./seedmap.js";

// parameters
let seed = Math.random();
let size = 64;
let count = 2;
// run...
let res = seedmap(seed, size, count);

response

console.log(res)
{
  dat: {pos: 4800, neg: 6400, time: 24.0},
  map: [canvas, canvas],
  max: 64,
  min: 4,
  seed: 12345678,
}
