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
```html
```
#### Minimum bundle example
This example is about 22k(gzipped) after bundled by webpack 4.0. It draws a triangle on the screen.
```js
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 } ]);
```
