NPM Version Circle CI

ClayGL is a WebGL graphic library for building scalable Web3D applications.

It's easy to use, configurable for high-quality graphics. Benefit from the modularity and tree shaking, it can be scaled down to 22k(gzipped) for a basic 3D application.

Quick Start

Create a rotating cube
<!DOCTYPE html>
<html lang="en">
  <script src="lib/claygl.js"></script>
  <canvas id="main"></canvas>
    clay.application.create('#main', {

      width: window.innerWidth,
      height: window.innerHeight,

      init(app) {
        // Create camera
        this._camera = app.createCamera([0, 2, 5], [0, 0, 0]);

        // Create a RED cube
        this._cube = app.createCube({
            color: '#f00'

        // Create light
        this._mainLight = app.createDirectionalLight([-1, -1, -1]);
      loop(app) {
        this._cube.rotation.rotateY(app.frameTime / 1000);

Minimum bundle example

This example is about 22k(gzipped) after bundled by webpack 4.0. It draws a triangle on the screen.

import { Renderer, GeometryBase, Shader, Material } from 'claygl';

const vsCode = `
attribute vec3 position: POSITION;
void main() {
    gl_Position = vec4(position, 1.0);
const fsCode = `
void main() {
    gl_FragColor = vec4(0.0, 0.0, 1.0, 1.0);

const renderer = new Renderer({
    canvas: document.getElementById('main')
renderer.resize(400, 400);

const geometry = new GeometryBase();
geometry.createAttribute('position', 'float', 3);
// Add triangle vertices to position attribute.
    [-0.5, -0.5, 0],
    [0.5, -0.5, 0],
    [0, 0.5, 0]

const material = new Material({
    shader: new Shader(vsCode, fsCode)
renderer.renderPass([ { geometry, material } ]);
