A WebGL graphic library for building scalable Web3D applications
ClayGL
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">
<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(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);
}
});
</script>
</body>

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.
geometry.attributes.position.fromArray([
[-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 } ]);
