Class NVTimelineSemaphore

java.lang.Object

org.lwjgl.opengl.NVTimelineSemaphore

public class NVTimelineSemaphore
extends Object

Native bindings to the NV_timeline_semaphore extension.

The Vulkan API introduces the concept of timeline semaphores. This extension brings those concepts to the OpenGL API by adding a semaphore type to the semaphore object. In OpenGL, timeline semaphore signal and wait operations are similar to the corresponding operations on imported Direct3D 12 fences defined in EXT_external_objects_win32.

Requires EXT_semaphore or a version of OpenGL that incorporates it.
