org.lwjgl.egl.EXTDeviceBase

public class EXTDeviceBase
extends java.lang.Object

Native bindings to the EXT_device_base 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 initialize EGL displays and surfaces directly on top of native GPU or device objects rather than native window system objects. The mechanics of enumerating the underlying native devices and constructing EGL displays and surfaces from them have been solved in various platform and implementation- specific ways. The EGL device family of extensions offers a standardized framework for bootstrapping EGL without the use of any underlying "native" APIs or functionality.

This extension defines the first step of this bootstrapping process: Device enumeration.
