> ![icon-note.gif](public_sys-resources/icon-note.gif) **Note：**
> The initial APIs of this module are supported since API version 7. Newly added APIs will be marked with a superscript to indicate their earliest API version.


This module provides WebGL APIs that correspond to the OpenGL ES 3.0 feature set. For more information, see [WebGL™](https://www.khronos.org/registry/webgl/specs/latest/2.0/).


## Modules to Import

  
```
import webgl from '@ohos.webglnapi';
```


## Invoking Method

Create a **&lt;canvas&gt;** component in the HML file. The following is an example:

  
```
<div class="container">
    <canvas ref="canvas1" style="width : 400px; height : 200px; background-color : lightyellow;"></canvas>
    <button class="btn-button" onclick="BtnDraw2D">BtnDraw2D</button>
</div>
```

Obtain the **&lt;canvas&gt;** component instance in the JS file. The following is an example:

  
```
// Obtain the <canvas> component instance.
const el = this.$refs.canvas1;
// Obtain the WebGL context from the <canvas> component instance.
const gl = el.getContext('webgl');
// Call the WebGL API.
gl.clearColor(0.0, 0.0, 0.0, 1.0);
```
