This is an experimental technologyCheck the Browser compatibility table carefully before using this in production.
The WebGL2RenderingContext.fenceSync()
method of the WebGL 2 API creates a new WebGLSync
object and inserts it into the GL command stream.
Syntax
WebGLSync gl.fenceSync(condition, flags);
Parameters
condition
- A
GLenum
specifying the condition that must be met to set the sync object's state to signaled. Must begl.SYNC_GPU_COMMANDS_COMPLETE
. - flags
- A
GLbitfield
specifying a bitwise combination of flags controlling the behavior of the sync object. Must be0
(exists for extensions only).
Return value
A WebGLSync
object.
Examples
gl
must be a WebGL2RenderingContext
. WebGLSync
objects are not available in WebGL 1.
var sync = gl.fenceSync(gl.SYNC_GPU_COMMANDS_COMPLETE, 0);
