Class KHRGLEvent

java.lang.Object

org.lwjgl.opencl.KHRGLEvent

public class KHRGLEvent
extends java.lang.Object

Native bindings to the khr_gl_event extension.

This extension allows creating OpenCL event objects linked to OpenGL fence sync objects, potentially improving efficiency of sharing images and buffers between the two APIs. The companion GL_ARB_cl_event extension provides the complementary functionality of creating an OpenGL sync object from an OpenCL event object.

In addition, this extension modifies the behavior of EnqueueAcquireGLObjects and EnqueueReleaseGLObjects to implicitly guarantee synchronization with an OpenGL context bound in the same thread as the OpenCL context.

                                              java.nio.IntBuffer errcode_ret)

Creates an OpenCL event object from an OpenGL fence sync object.

Parameters:

context - the OpenCL context in which to create the event object

sync - the OpenGL fence sync object

errcode_ret - will return an appropriate error code. If errcode_ret is NULL, no error code is returned.
