WebGLSync

Baseline Widely available

This feature is well established and works across many devices and browser versions. It’s been available across browsers since September 2021.

Note: This feature is available in Web Workers.

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

WebGLObject WebGLSync

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

Examples

Creating a WebGLSync object

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

js
const sync = gl.fenceSync(gl.SYNC_GPU_COMMANDS_COMPLETE, 0);
