Toxiclibs.js is a port of Karsten Schmidt's Toxiclibs for Java and Processing. Toxiclibs.js provides powerful datatypes for the browser and node. It works well for manipulating any DOM element, including Canvas and SVG.

The plethora of examples demonstrate its use for geometry and color manipulation as well as physics, automata and more. The examples pair with such fine libraries as: Processing.js, Three.js, D3.js or Raphael.js.

What it is…

  • 2D/3D geometry
  • Mesh generation and subdivision
  • Interpolation / Mapping
  • Wave Generators
  • 2D physics simulation
  • Color theory sorting and conversion

Getting Started with Toxiclibs.js

Toxiclibs.js can be used in the following ways:

  • As a single javascript file loaded into a webpage, with the contents of the entire library within a global toxi object.
  • As AMD modules that can be loaded independently or in packages, via RequireJS
  • In Node.js applications, as AMD modules that require the 'requirejs' library for Node.js.

Use the build

copy the file build/toxiclibs.js:

<script type="text/javascript" src="js/toxiclibs.js"></script>
<script type="text/javascript">
	var myVector = new toxi.geom.Vec2D(window.innerWidth,window.innerHeight).scaleSelf(0.5);
	var myColor = toxi.color.TColor.newRGB(128/255,64/255,32/255);

Use with RequireJS or other AMD loader

copy the contents of lib/:

require(['toxi/geom/Vec2D', toxi/color/TColor], function(Vec2D, TColor){
	var myVector = new Vec2D(window.innerWidth,window.innerHeight).scaleSelf(0.5);
	var myColor = TColor.newRGB(128/255,64/255,32/255);

Use with Node.js:

npm install toxiclibsjs


var	toxi = require('toxiclibsjs'),
	myVector = new toxi.geom.Vec2D(0.5,0.5),
	myColor = toxi.color.TColor.newRGB(128/255,64/255,32/255);

For comprehensive documentation, read the original libraries javadocs. As the library is still growing, you can compare that documentation to this list of implemented classes.

Toxiclibs.js follows the original package structure

The following objects are returned when loading the entire library

  • color - the color utils package (view doc)
  • geom - the geometry utils package
  • internals - functionality used within the library
  • math - the math utils package
  • physics2d - the Verlet Physics 2D package
  • processing - the processing package, eases use with Processing.js
  • THREE - features to ease use with Three.js
  • utils - the utils package

Creating Builds

Run make to generate new versions of the existing builds. There are additional targets defined in the Makefile ###Custom builds If you are working with the build/ files you may wish to create a custom build that only includes the modules you are using in order to save file size. If you are using the files as AMD modules there is no need for this.

To generate a custom build, space-delimit the modules you want:

./bin/toxiclibsjs --include "toxi/geom/Vec2D toxi/physics2d" --minify --out "./build/toxiclibsjs-custom.min.js"

Run the tests

Run make test to run the suite of tests.
