canvas-sketch-util-umd

A fork of Matt DesLauriers' 1.10.0 build of canvas-sketch-util to include a UMD build.

All credit to the original author. This repo is just for testing for my owm purposes and hopfully he may accept a pull request for this code later.

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

Features

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)
• shader - A full-screen GLSL shader utility

The following are planned but not yet implemented:

• tween - Tweening, easing & animation utilities

And more to come...
