6. Canvas JavaScript library

ArtisanJS is a JavaScript library that aims to make in-browser drawing very, very easy.

Burst is a javascript vector animation engine for the HTML5 Canvas supporting SVGs, Blender3D objects, timelines, easing, command chaining and callbacks

CAAT: Canvas Advanced Animation Tookit CAAT in essence is a multi-instance director-based Scene graph manager.

canto.js is a small JavaScript library that improves the HTML5 Canvas drawing API to support features such as:

• method chaining
• relative coordinates
• polylines
• SVG path commands
• turtle graphics
• easier specification of drawing attributes

CAKE is a JavaScript scene graph library for the HTML5 canvas tag. You could think of it as SVG sans the XML and not be too far off.

CamanJS is an attempt at providing a simple to use interface for dynamically manipulating images completely in JS. It strives to provide much of the basic functionality you would find in something like Photoshop. By this I mean, image contrast, brightness, levels, saturation, etc.

Wrapper for HTML5 Canvas Context 2D properties and methods, enabling chaining.

It�s intended to be simple, small and not add new functionalities besides method chaining, it doesn�t overwrite the native prototypes/objects and can be used interchangeably with native Context2D methods/properties, works just as a wrapper to native calls.

canvg is a Javascript SVG parser and renderer. It takes a URL to a SVG file or the text of an SVG file, parses it in JavaScript, and renders the result on a Canvas element. The rendering speed of the examples is about as fast as native SVG.

• Use the Canvas drawing API with sprites and a scene graph.
• Event handling and dispatch for objects.
• Nodes maintain transforms, bounds, and other useful properties.
• If you�re coming from ActionScript 3, you�ll feel right at home!

The new Canvas element in HTML5 is powerful, but it can be difficult to work with. It has no internal concept of discrete display elements, so you are required to manage updates manually. The Easel Javascript library provides a full, hierarchical display list, a core interaction model, and helper classes to make working with Canvas much easier.

gury.js is a jQuery inspired canvas utility library.

Fabric.js is a framework that makes it easy to work with HTML5 canvas element. It is an interactive object model on top of canvas element. It is also an SVG-to-canvas parser.

Using Fabric.js, you can create and populate objects on canvas; objects like simple geometrical shapes � rectangles, circles, ellipses, polygons, or more complex shapes consisting of hundreds or thousands of simple paths. You can then scale, move, and rotate these objects with the mouse; modify their properties � color, transparency, z-index, etc. You can also manipulate these objects altogether � grouping them with a simple mouse selection.

A basic HTML 5 canvas drawing library for those familiar with the java.awt.Graphics class in Java. It also comes with a JavaScript implementation of the game Breakout to demonstrate using the library.

The Layered Canvas Library (LCL) is a javascript library that helps manage objects on the Canvas element. The LCL implements a two tier layer manager that creates and contains items within it. The layer manager attaches mouse events to each item contained, and allows the user to define handlers for each event, per item.

The layer manager also allows for each layer contained to be promoted, or demoted over another layer. The layer manager, and each layer, and item contained, is defined with a draw function. The draw function executes user defined code to draw the item, layer, or each layer contained consecutively.

This library provides functionality to manage and interact with the content of a html5 canvas element. It emulates layers and items that can be manipulated and managed and provides mouse-events to the items.

This library is inspired by Michael Camden�s layered-canvas-library but I made this one a little more compact, skipped some features, added some and tried to streamline the way the lib is interacted with. It is built utilizing many features of the MooTools javascript framework which is responsible for reduced filesize, great OOP and flexible events.

Pixastic is a JavaScript library which allows you to perform a variety of operations, filters and fancy effects on images using just a bit of JavaScript.

Processing.js is the sister project of the popular Processing visual programming language, designed for the web. Processing.js makes your data visualizations, digital art, interactive animations, educational graphs, video games, etc. work using web standards and without any plug-ins.

You write code using the Processing language, include it in your web page, and Processing.js does the rest. It�s not magic, but almost.

Rapha�l is a small JavaScript library that should simplify your work with vector graphics on the web. If you want to create your own specific chart or image crop and rotate widget, for example, you can achieve it simply and easily with this library.

Stackblur is a Javascript / Canvas based implementation library.

Toxiclibs.js is a javascript port of Karsten Schmidt�s Toxiclibs for Java and Processing. Toxiclibs.js works great with the Processing.js visualization library for but is not dependent on it. It can be used with other libraries such as Raphael.js, Three.js or by itself.

Unveil is a data exploration and visualization toolkit that utilizes data-driven software design.

7. WebGL

8. Color

color.js can be used in any ECMAScript environment as it does not make use of the DOM. color.js is very useful on the server-side and the client-side, The color.js CSS module defines all of the standard CSS colors for use in color.js.

9. Math

Sylvester is a JavaScript library designed to let you do mathematics with vectors and matrices without having to write lots of loops and throw piles of arrays around.

It includes classes for modelling vectors and matrices in any number of dimensions, and for modelling infinite lines and planes in 3-dimensional space. It lets you write object-oriented easy-to-read code that mirrors the maths it represents.
