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()WebGL2RenderingContext.deleteSync()WebGL2RenderingContext.isSync()WebGL2RenderingContext.clientWaitSync()WebGL2RenderingContext.waitSync()WebGL2RenderingContext.getSyncParameter()
Examples
Creating a WebGLSync object
in this example, gl must be a WebGL2RenderingContext. WebGLSync objects are not available in WebGL 1.
var sync = gl.fenceSync(gl.SYNC_GPU_COMMANDS_COMPLETE, 0);
