<div>{{APIRef("WebGL")}} {{SeeCompatTable}}</div>
<p>The <strong><code>WebGLSync</code></strong> interface is part of the <a href="/en-US/docs/Web/API/WebGL_API">WebGL 2</a> API and is used to synchronize activities between the GPU and the application.</p>
<p>When working with <code>WebGLSync</code> objects, the following methods of the {{domxref("WebGL2RenderingContext")}} are useful:</p>
<ul>
<li>{{domxref("WebGL2RenderingContext.fenceSync()")}}</li>
<li>{{domxref("WebGL2RenderingContext.deleteSync()")}}</li>
<li>{{domxref("WebGL2RenderingContext.isSync()")}}</li>
<li>{{domxref("WebGL2RenderingContext.clientWaitSync()")}}</li>
<li>{{domxref("WebGL2RenderingContext.waitSync()")}}</li>
<li>{{domxref("WebGL2RenderingContext.getSyncParameter()")}}</li>
</ul>
<h2 id="示例">示例</h2>
<h3 id="创建一个WebGLSync对象">创建一个WebGLSync对象</h3>
<p>in this example, <code>gl</code> must be a {{domxref("WebGL2RenderingContext")}}. <code>WebGLSync</code> objects are not available in WebGL 1.</p>
<pre class="brush: js">var sync = gl.fenceSync(gl.SYNC_GPU_COMMANDS_COMPLETE, 0);</pre>
