WebGLSync

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() (en-US)
• WebGL2RenderingContext.deleteSync() (en-US)
• WebGL2RenderingContext.isSync() (en-US)
• WebGL2RenderingContext.clientWaitSync() (en-US)
• WebGL2RenderingContext.waitSync() (en-US)
• WebGL2RenderingContext.getSyncParameter() (en-US)

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