FigureOne

Draw, animate and interact with shapes, text, plots and equations.

This JavaScript library can be used for making animated and/or interactive content for the web including: * Diagrams * Equations * Plots * Presentations or slide shows * Video-like experiences

Note: for the video-like experiences, FigureOne creates a custom vector video format which is interactive, resolution independent, and a fraction of the size of an normal audio track. This results in very low bandwidth video. For example, 4 minutes of animated content might result in a video track 70KB in size. See below for some examples of interactive videos. More information on this, and the trade-offs with traditional video can be found in the API Reference.

FigureOne can also be used to create animations (like equation animations) that can then be screen captured and merged into a standard video file.

See the Tutorials, API Reference and Examples and you'll be making beautiful, interactive figures in no time.

The examples are also hosted (and thus can be directly interacted with) on this repository's GitHub Pages site here.

Getting Started

Load the FigureOne library into your HTML file:

<script type="text/javascript" src='https://cdn.jsdelivr.net/npm/figureone@0.10.2/figureone.min.js'></script>

Create a div element to attach the figure to:

Then in javascript, create a figure and a shape within it:

const figure = new Fig.Figure();

// Create the shape
const tri = figure.add({
  make: 'triangle',
  color: [1, 0, 0, 1],
});

// Animate the shape
tri.animations.new()
  .position(0.5, 0)
  .rotation(Math.PI)
  .position(0, 0)
  .start();

And you will see:

The Tutorials build on this and introduce FigureOne's concepts and features in simplified examples. The API Reference describes these concepts in more depth as well as provides detailed API documentation. Consider reviewing these first before diving into the code of the examples below.

Demonstrator of how shaders can be used to animate over 1000 elements simultaneously and still get excellent performance on low end clients.

NPM Package

On projects that are bundled with tools such as Webpack, it can be useful to use the FigureOne NPM package:

npm install figureone

Then within your project you can:

import Fig from 'figureone';

const figure = new Fig.Figure();

Flow typed files are included in the package for type checking in the editor.
