# @antv/g-webgl

This is a renderer implemented with WebGL2/1.

```js
import { Renderer as WebGLRenderer } from '@antv/g-webgl';

const webglRenderer = new WebGLRenderer();

// create a canvas
const canvas = new Canvas({
    container: 'container',
    width: 600,
    height: 500,
    renderer: webglRenderer,
});
```

## Options

### targets

```js
new Renderer({
    targets: ['webgl2', 'webgl1'],
});
```
