Manim.js

This repo contains the source code for all animations of my YouTube channel, Jazon Jiao (Subscribe!): https://www.youtube.com/channel/UC8bvGUlaTahF0lHhMsZFhfw

Manim.js is a project that aims to emulate 3b1b-style math animations using JavaScript (p5.js). The library is currently focused on visualizing linear algebra concepts and graph algorithms. All util classes are located in /src, with detailed documentation. Feel free to use my tools to make your own visualizations of math or CS concepts!

As an example, here's how you could create an simple graph. Include this code and other necessary source files in an html file (see, for example, Graph Algorithms/graph.html), and then open the browser.

let G = {
    V: [[100, 200],  // vertex 0 coordinates on canvas
        [260, 100],  // vertex 1
        [260, 300],  // vertex 2
        [420, 200],  // vertex 3
    ],
    E: [[0, 1], [0, 2], [1, 2], [1, 3], [2, 3]]  // edges
};

const GraphExample = function(s) {
    let tnr;
    s.preload = function() {
        tnr = s.loadFont('../lib/font/times.ttf');    // loads font (Times new roman)
    };
    s.setup = function () {
        // this sets frameRate to be 30, and creates a canvas of 1200 by 675 (you can adjust these in globals.js)
        setup2D(s); 

        // creates an undirected graph
        s.g = new Graph_U(s, {  // parameters are passed in via an object
            V: G.V, 
            E: G.E, 
            font: tnr,
            start: 40,   // the time to start the animation in frames
            color_e: [7, 97, 7],   // color of edges in RGB
            color_v: Yellow,   // set color of nodes, using the global Yellow variable
        });
    };
    s.draw = function () {
        s.background(0);
        s.g.show();  // Manim.js classes usually define a show() function to be called in draw()
    };
};

let p = new p5(GraphExample);   // creates the p5 object to render the animation
