WebGLSync

{{APIRef("WebGL")}}{{AvailableInWorkers}}

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

{{InheritanceDiagram}}

When working with WebGLSync objects, the following methods of the {{domxref("WebGL2RenderingContext")}} are useful:

• {{domxref("WebGL2RenderingContext.fenceSync()")}}
• {{domxref("WebGL2RenderingContext.deleteSync()")}}
• {{domxref("WebGL2RenderingContext.isSync()")}}
• {{domxref("WebGL2RenderingContext.clientWaitSync()")}}
• {{domxref("WebGL2RenderingContext.waitSync()")}}
• {{domxref("WebGL2RenderingContext.getSyncParameter()")}}

Examples

Creating a WebGLSync object

in this example, gl must be a {{domxref("WebGL2RenderingContext")}}. WebGLSync objects are not available in WebGL 1.

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