> 本模块首批接口从API version 7开始支持。后续版本的新增接口，采用上角标单独标记接口的起始版本。
WebGL标准图形API，对应OpenGL ES 2.0特性集。更多信息请参考[WebgGL™标准](https://www.khronos.org/registry/webgl/specs/latest/1.0/)。

## 导入模块
```
import webgl from 'ohos.webglnapi'
import webgl from '@ohos.webglnapi'
```
## 系统能力
## 调用方式
SystemCapability.Graphic.Graphic2D.WebGL
hml内创建canvas，示例如下：
## 调用方式
```
<div class="container">
<canvas ref="canvas1" style="width : 400px; height : 200px; background-color : lightyellow;"></canvas>
<button class="btn-button" onclick="BtnDraw2D">BtnDraw2D</button>
</div>
```
js内获取canvas实例，示例如下：
```
// 获取canvas组件实例
const el = this.$refs.canvas
const el = this.$refs.canvas1;
// 从canvas组件实例获取WebGL上下文
const gl = el.getContext('webgl');
// 调用WebGL API
gl.clearColor(0.0, 0.0, 0.0, 1.0);
gl.flush();
```

## 导入模块
```
import webgl from 'ohos.webglnapi'
import webgl from '@ohos.webglnapi'
```
## 系统能力
## 调用方式
SystemCapability.Graphic.Graphic2D.WebGL2
hml内创建canvas，示例如下：
## 调用方式
```
<div class="container">
<canvas ref="canvas1" style="width : 400px; height : 200px; background-color : lightyellow;"></canvas>
<button class="btn-button" onclick="BtnDraw2D">BtnDraw2D</button>
</div>
```
js内获取canvas实例，示例如下：
```
// 获取canvas组件实例
const el = this.$refs.canvas
const el = this.$refs.canvas1;
// 从canvas组件实例获取WebGL上下文
const gl = el.getContext('webgl');
const gl2 = el.getContext('webgl2');
// 调用WebGL API
gl2.readBuffer(gl.COLOR_ATTACHMENT0)
gl.clearColor(0.0, 0.0, 0.0, 1.0);
```
