ClayGL

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 40k(gzipped) for a basic 3D application.

Quick Start

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

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

      init: function (renderer, scene, timeline) {
        // 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: function (renderer, scene, timeline) {
        this._cube.rotation.rotateY(this.frameTime / 1000);
      }
    });
