The WebGL2RenderingContext.waitSync() method of the WebGL 2 API returns immediately, but waits on the GL server until the given WebGLSync object is signaled.
The method is a no-op in the absence of the possibility of synchronizing between multiple GL contexts.
waitSync(sync, flags, timeout)
sync
A WebGLSync object on which to wait on.
A GLbitfield specifying a bitwise combination of flags controlling the flushing behavior. Must be 0 (exists for extensions only).
A GLint64 specifying a timeout the server should wait before continuing. Must be gl.TIMEOUT_IGNORED.
None.
var sync = gl.fenceSync(gl.SYNC_GPU_COMMANDS_COMPLETE, 0); gl.waitSync(sync, 0, gl.TIMEOUT_IGNORED);
