This library allows for using OpenGL and Vulkan LWJGL 3 surfaces in AWT (and by extension, Swing) frames. Works with MacOS X, Windows, and Linux.

What does it get me?

Support for OpenGL:

• creating OpenGL 3.0 and 3.2 core/compatibility contexts (including debug/forward compatible)
• OpenGL ES contexts
• floating-point and sRGB pixel formats
• multisampled framebuffers (also with different number of color samples - Nvidia only)
• v-sync/swap control
• context flush control
• robust buffer access (with application/share-group isolation)
• sync'ing buffer swaps over multiple windows and cards - Nvidia only
• delay before swap - Nvidia only

Support for Vulkan:

• Vulkan 1.0, 1.1, 1.2, 1.3
• MoltenVK support

Note about compatibility: The minimum macOS version for OpenGL is 10.5, and the minimum for Vulkan is 10.11, since Vulkan runs on top of the Metal API introduced in that version.

How to use

OpenGL

In order to create an OpenGL 3.3 core profile context with 4 sample MSAA, use:

JFrame frame = new JFrame("AWT test");
frame.setDefaultCloseOperation(JFrame.DISPOSE_ON_CLOSE);
frame.setLayout(new BorderLayout());
GLData data = new GLData();
data.majorVersion = 3;
data.minorVersion = 3;
data.profile = GLData.Profile.CORE;
data.samples = 4;
frame.add(new AWTGLCanvas(data) {
  public void initGL() {
  }
  public void paintGL() {
  }
});

Vulkan

if (!AWTVK.isPlatformSupported()) {
	throw new RuntimeException("Platform not supported.");
}

JFrame frame = new JFrame("AWT test");
frame.setDefaultCloseOperation(JFrame.DISPOSE_ON_CLOSE);
frame.setLayout(new BorderLayout());
frame.setPreferredSize(new Dimension(600, 600));
Canvas canvas = new Canvas();
frame.add(canvas, BorderLayout.CENTER);
frame.pack(); // Packing causes the canvas to be lockable, and is the earliest time it can be used

long surface = AWTVK.create(canvas, instance);

// Do things with the surface

frame.setVisible(true);
frame.addWindowListener(new WindowAdapter() {
    @Override
    public void windowClosing(WindowEvent e) {
        super.windowClosing(e);
		
        // Destroy the surface to prevent leaks and errors
        KHRSurface.vkDestroySurfaceKHR(instance, surface, null);
}});
