# WebGL
WebGL提供图形绘制的能力，包括对当前绘制图形的位置、颜色等进行处理。
WebGL标准图形API，对应OpenGL ES 2.0特性集。更多信息请参考[WebGL™标准](https://www.khronos.org/registry/webgl/specs/latest/1.0/)。
> **说明：**
>
> 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遵循OpenGL协议，不支持多线程调用。
>
> 目前该功能仅支持使用兼容JS的类Web开发范式开发。
## 调用方式
hml内创建canvas，示例如下：
```html
<!--xxx.hml-->
<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：
```js
// 获取canvas组件实例
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);
```

# WebGL2
WebGL2支持图形的绘制，包括对当前绘制图形的位置、颜色等进行处理，其中相对WebGL来说对渲染管道和着色语言进行了增强。
WebGL标准图形API，对应OpenGL ES 3.0特性集。更多信息请参考[WebGL™标准](https://www.khronos.org/registry/webgl/specs/latest/2.0/)。
> **说明：**
>
> 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。
>
> WebGL2遵循OpenGL协议，不支持多线程调用。
>
> 目前该功能仅支持使用兼容JS的类Web开发范式开发。
## 调用方式
hml内创建canvas，示例如下：
```html
<!--xxx.hml-->
<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：
```js
// 获取canvas组件实例
const el = this.$refs.canvas1;
// 从canvas组件实例获取WebGL上下文
const gl = el.getContext('webgl2');
// 调用WebGL API
gl.clearColor(0.0, 0.0, 0.0, 1.0);
```
