This is an experimental technology
Because this technology's specification has not stabilized, check the compatibility table for usage in various browsers. Also note that the syntax and behavior of an experimental technology is subject to change in future versions of browsers as the specification changes.
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()
WebGLSync
objectin 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);
