See fractal-noise-js (Deno: fractal_noise, NPM: fractal-noise) for higher order noise shapes.

Each make function takes a random function (() => number)) as its argument, defaulting to Math.random.

Returns a two-dimensional noise generation function.

Returns a three-dimensional noise generation function.

Returns a four-dimensional noise generation function.
