This is an experimental technology
Check the Browser compatibility table carefully before using this in production.
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);
