描述

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。

说明：
开发前请熟悉鸿蒙开发指导文档 ：[gitee.com/li-shizhen-skin/harmony-os/blob/master/README.md]
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。

调用方式

hml内创建canvas，示例如下：

< !--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：

// 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);
