noise.js

a javascript simple noise generator based on code from from scratchapixel.com, via Michael Bromley

Installation

npm install yy-noise

API Reference

creates simple 1D noise this.generator

Kind: global class

• SimpleNoise
  • new SimpleNoise(options, [maxVertices], [amplitude], [scale])
  • .get(x) ⇒ number
  • .lerp(a, b, t) ⇒ number

new SimpleNoise(options, [maxVertices], [amplitude], [scale])

| Param | Type | Default | | --- | --- | --- | | options | object | | | [maxVertices] | number | 256 | | [amplitude] | number | 1 | | [scale] | number | 1 |

Example

const noise = new SimpleNoise({maxVertices: 512, noise: 0.5, scale: 0.25});

     // changes amplitude of noise function
     noise.amplitude = amplitude;

     // sets scale of noise function
     noise.scale = scale;

     // returns the value based on n (usually incremented along an axis)
     for (let x = 0; x < 100; x++)
     {
         noise.get(n);
     }

simpleNoise.get(x) ⇒ number

gets a value

Kind: instance method of SimpleNoise

| Param | Type | | --- | --- | | x | number |

simpleNoise.lerp(a, b, t) ⇒ number

Linear interpolation function.

Kind: instance method of SimpleNoise

| Param | Type | Description | | --- | --- | --- | | a | number | The lower integer value | | b | number | The upper integer value | | t | number | The value between the two |
