AMDOcclusionQueryEvent (LWJGL 3.1.1 SNAPSHOT - OpenGL)

java.lang.Object
- org.lwjgl.opengl.AMDOcclusionQueryEvent

```
public class AMDOcclusionQueryEvent
extends java.lang.Object
```
Native bindings to the AMD_occlusion_query_event extension.
This extension introduces the concept of occlusion query events and changes the concept of an occlusion query from counting passed fragments to counting fragments that generate any of a user-selectable set of events. Provided events include passing the depth test, and passing or failing the stencil test. For a given occlusion query object, counting of these events may be enabled or disabled, allowing any combination to be counted.

Requires OpenGL 1.5.
