mraph

Mraph.js is my poor animation engine for drawing geometric shapes in a browser, inspired by manim
Github | NPM | Examples

Usage

Install with npm:

npm install --save mraph

or use yarn:

yarn add mraph

A short example:

Once you installed, try this example below.

import * as MRAPH from "mraph";

// Creates a new layer
const layer = new MRAPH.Layer().appendTo(document.body);

// Creates some points and sets their position
const pointsNum = 50;
const layersNum = 5;
const angleUnit = (Math.PI * 2) / pointsNum;
for (let j = 0; j < layersNum; j++) {
    for (let i = 1; i <= pointsNum; i++) {
        const point = new MRAPH.Point(Math.cos(angleUnit * i) * (3 + j * 2), Math.sin(angleUnit * i) * (3 + j * 2));
        point.setColor(new MRAPH.Color(Math.random(), Math.random(), Math.random()));
        layer.add(point);
    }
}

// Sets an infinite event
// This event will remain perpetually active
layer.timeline.addInfinite(() => {
    layer.scene.children.forEach((point, i, arr) => {
        point.a = point.center.mult((-1 * i) / arr.length);
    });
});

// Starts playing animation
layer.enableOrbitControl().enableRotate = false;
layer.play();

Input this code in your preferred text editor. If all proceeds as it should, you will observe a series of dots engaged in a, hmm..., rather peculiar dance.
