WebGLSync

Available in workers

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:

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

Examples

Creating a WebGLSync object

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

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