This is an experimental technologyCheck the Browser compatibility table carefully before using this in production.
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.
Syntax
void gl.waitSync(sync, flags, timeout);
Parameters
sync
- A
WebGLSync
object on which to wait on. - flags
- A
GLbitfield
specifying a bitwise combination of flags controlling the flushing behavior. Must be0
(exists for extensions only). - timeout
- A
GLint64
specifying a timeout the server should wait before continuing. Must begl.TIMEOUT_IGNORED
.
Return value
None.
Examples
var sync = gl.fenceSync(gl.SYNC_GPU_COMMANDS_COMPLETE, 0);
gl.waitSync(sync, 0, gl.TIMEOUT_IGNORED);
