WebGLSync - Web API 接口参考 编辑

这是一个实验中的功能
此功能某些浏览器尚在开发中，请参考浏览器兼容性表格以得到在不同浏览器中适合使用的前缀。由于该功能对应的标准文档可能被重新修订，所以在未来版本的浏览器中该功能的语法和行为可能随之改变。

The WebGLSync interface is part of the WebGL 2 API and is used to synchronize activities between the GPU and the application.

When working with WebGLSync objects, the following methods of the WebGL2RenderingContext are useful:

• WebGL2RenderingContext.fenceSync()
• WebGL2RenderingContext.deleteSync()
• WebGL2RenderingContext.isSync()
• WebGL2RenderingContext.clientWaitSync()
• WebGL2RenderingContext.waitSync()
• WebGL2RenderingContext.getSyncParameter()

示例

创建一个WebGLSync对象

in this example, gl must be a WebGL2RenderingContext. WebGLSync objects are not available in WebGL 1.

var sync = gl.fenceSync(gl.SYNC_GPU_COMMANDS_COMPLETE, 0);
