canvas-sketch-util

Utilities for generative art in Canvas, WebGL and JavaScript.

This is designed to be used alongside the canvas-sketch toolset, but it is generic enough to work for various Node.js/Browser use cases.

Example

You can require each module individually, and grab only the necessary functions.

Some examples:

const math = require('canvas-sketch-util/math');
 
console.log(math.clamp(1.25, 0, 1));
// 1

Or by using destructuring to grab only a select few functions:

const { fract, lerp } = require('canvas-sketch-util/math');
 
console.log(fract(51.23));
// 0.23
 
console.log(lerp(0, 50, 0.5));
// 25

The random utility has been inspired by Unity3D, as well as other engines.

const random = require('canvas-sketch-util/random');
 
console.log(random.value());
// some random number between 0 (inclusive) and 1 (exclusive)
 
// Create a seeded random generator
const seeded = random.createRandom(25);
 
console.log(seeded.range(25, 50));
// some deterministic random number
 
console.log(seeded.shuffle([ 'a', 'b', 'c' ]));
// deterministically shuffles a copy of the array

The following modules have been implemented:

  • math - Math & interpolation utilities
  • random - A random number generator
  • color - RGB and HSL color utilities
  • geometry - Utilities for geometry & shapes
  • penplot - Utilities for working with pen plotters (e.g. AxiDraw)
