Class EXTDeviceQuery

java.lang.Object

org.lwjgl.egl.EXTDeviceQuery

public class EXTDeviceQuery
extends java.lang.Object

Native bindings to the EXT_device_query extension.

Increasingly, EGL and its client APIs are being used in place of "native" rendering APIs to implement the basic graphics functionality of native windowing systems. This creates demand for a method to access native GPU or device objects directly rather than calling EGL or GL entry points.

This extension defines the method for an application to query native device objects from an EGL Display.

Requires EGL 1.5 or an earlier verison of EGL with the EXT_device_query extension.
