WARNING: This document is under review.


The JOGL project hosts the development version of the Java™ Binding for the OpenGL® API, and is designed to provide hardware-supported 3D graphics to applications written in Java.

It provides full access to the APIs in the OpenGL 1.3 - 3.0, 3.1 - 3.3, ≥ 4.0, ES 1.x and ES 2.x specification as well as nearly all vendor extensions. OpenGL Evolution & JOGL (UML) gives you a brief overview of OpenGL, its profiles and how we map them to JOGL.

It integrates with the AWT, Swing and SWT widget sets, as well with custom windowing toolkits using the NativeWindow API. JOGL also provides its own native windowing toolkit, NEWT.

AWT integration is available via AWT GLCanvas and NEWT's NewtCanvasAWT, where Swing integration is available via GLJPanel.

SWT integration is available via SWT GLCanvas and by using the SWT/AWT brigde.

Other windowing systems or widgets sets can be implemented by using the NativeWindow API.

Jogl provides access to the latest OpenGL routines (OpenGL 4.x with nearly all vendor extensions) as well as platform-independent access to hardware-accelerated offscreen rendering ("pbuffers"). Jogl also provides some of the most popular features introduced by other Java bindings for OpenGL like GL4Java, LWJGL and Magician, including a composable pipeline model which can provide faster debugging for Java-based OpenGL applications than the analogous C program and a native windowing toolkit independent of AWT called NEWT.

Jogl is designed for the most recent versions of the Java platform and for this reason supports only:
  • Java 1.6 (Level 6.0)
    • J2SE ≥ 1.6 (OpenJDK, Oracle, ..)
    • JavaSE ≥ 1.6 For Embedded (Oracle)
  • Android SDK API Level 9 (Version 2.3 Gingerbread)

It also only supports truecolor (15 bits per pixel and higher) rendering; it does not support color-indexed modes. It was designed with New I/O (NIO) in mind and often uses NIO internally in the implementation. Nevertheless non NIO/direct buffers/arrays are supported as well, since they allow faster processing on CPU intensive tasks. The Jogl binding is itself written almost completely in the Java programming language. Most of the native code is autogenerated during the build process by a new tool called GlueGen, the source code of which is available from its own jogamp.org project.

Accessing JOGL

Building the source tree

Most developers using JOGL will download the most current release build. Separate instructions are available on how to build the source tree.

Local Installation

See deployment for deployment details.

7zip Archives

A 7zip archive for all platforms and all JogAmp modules including JOGL is available, named jogamp-all-platforms.7z, as available here. It contains the Java classes to call OpenGL from Java, as well as the associated JNI native libraries. JOGL depends on some run-time support classes and native code provided by the GlueGen project; these classes and native code are also provided in the 7zip bundles.


Modify your CLASSPATH environment variable to include the full paths to gluegen-rt.jar and jogl-all.jar, for example
(If you did not previously set the CLASSPATH environment variable, you may want to make sure that ".", the current directory, is on your new CLASSPATH.) The path separator is ":" under Solaris, Mac and Linux.
Atomic JAR files

Note that the 7zip archive contain more jar files than just the above mentioned. Additional atomic jars jogamp-all-platforms/jar/atomic/ illustrate how JOGL may be partitioned to achieve a smaller deployment size, in particular on smaller devices. See deployment for details.

Automated Native Library Loading

JOGL 2.0 has a brand new feature allowing to automatically extract the proper native libraries required to use JOGL from JARs containing them without relying on the Java library path or any platform-dependent environment variable allowing to set the location of native libraries. This allows desktop applications as well as traditional Applets as NApplets to utilize the native library JAR files the same way Webstart/JNLP does.

To allow the native JAR file library loading to work, ensure that all JogAmp JAR files are left unmodified within their common directory.

In case the native library JAR files cannot be opened, it falls back to the traditional native library loading mechanism via the java library path.

This feature is enabled by default and - for whatever reason - it can be disabled by setting the property jogamp.gluegen.UseTempJarCache to false (as a VM argument, -Djogamp.gluegen.UseTempJarCache=false in command line).

Traditional Native Library Loading

If you don't use automatic native libraries loading, as enabled by default, you must set either the VM property java.library.path or the platform-dependent environment variable used for the location of native libraries, PATH on Windows, LD_LIBRARY_PATH on Unix (Linux, Solaris, ..) and DYLD_LIBRARY_PATH on Mac OS X. The environment variable shall contain the full path to the "lib" directory; for example, on Windows, add "C:\Users\myhome\jogamp-all-platforms\lib\windows-amd64" to your PATH using the System control panel, Advanced tab, Environment Variables button. At this point your Java installation should be able to see the Jogl class files.

Settings for IDE's users

Eclipse users must add the JARs containing Java libraries into the Java Build Path of their project. They must set the native library location of these JARs if they have disabled the automatic extraction of native libraries. Netbeans users must add the JARs containing Java libraries into their project. In the “project” tab, select the "Libraries" node, select the item "Add JAR/Folder" and select the required JARs. Users of other IDEs should consult the IDE's documentation to see how to add jar files and native libraries to their current project.

Bad practice

Dropping the JOGL jars and native libraries into the extension directory of the JRE is strongly discouraged. Doing so will cause conflicts with third-party applications launched via Java Web Start, and causes confusion later when upgrading the distribution.

If you are on the Linux platform, please see the Linux-specific platform notes, below, with information on incompatibility between the JPackage Java RPMs and JOGL.

Note for Debian Linux users

DEB packages are available for this distribution on its official repositories.

Online Deployment

The recommended distribution vehicle for online applications using JOGL is either using Applets or Java Web Start. JOGL-based applications do not even need to be signed; all that is necessary is to reference the online resources using the appropriate URLs.

Please read JOGL Deployment.

Using the JOGL API

GLDrawable and GLContext

The APIs specify interfaces two low-level OpenGL abstractions: drawables and contexts. An OpenGL drawable is effectively a surface upon which OpenGL rendering will be performed. In order to perform rendering, an OpenGL rendering context is needed. Contexts and drawables typically go hand-in-hand. More than one context may be created for a particular drawable. In these abstractions, a context is always associated with exactly one drawable.

Most end users will not need to use these abstractions directly. However, when sharing textures, display lists and other OpenGL objects between widgets, the concrete identifier for the "namespace" for these objects is the GLContext.


GLProfile instances maps OpenGL profiles introduced in OpenGL 3, please read this for more details.

Creating a GLAutoDrawable

Jogl provides three basic widgets into which OpenGL rendering can be performed. The GLCanvas is a heavyweight AWT widget which supports hardware acceleration and which is intended to be the primary widget used by applications. The GLJPanel is a fully Swing-compatible lightweight widget which supports hardware acceleration but which is not as fast as the GLCanvas because it typically reads back the frame buffer in order to draw it using Java2D. The GLJPanel is intended to provide 100% correct Swing integration in the circumstances where a GLCanvas can not be used. See this article on The Swing Connection for more information about mixing lightweight and heavyweight widgets. See also the section on "Heavyweight and Lightweight Issues" below. Recent work in the Mustang release of the JDK has sped up the GLJPanel significantly when the Java2D OpenGL pipeline is enabled; see this forum discussion for more details. GLWindow is a NEWT widget which supports hardware acceleration and which is intended to be the primary widget used by AWT-less applications.

GLCanvas, GLWindow and GLJPanel implement a common interface called GLAutoDrawable so applications can switch between them with minimal code changes. The GLAutoDrawable interface provides
  • access to the GL object for calling OpenGL routines
  • a callback mechanism (GLEventListener) for performing OpenGL rendering
  • a display() method for forcing OpenGL rendering to be performed synchronously
  • AWT- and Swing-independent abstractions for getting and setting the size of the widget and adding and removing event listeners

When creating GLCanvas, GLWindow and GLJPanel instances, the user may request a certain set of OpenGL parameters in the form of a GLCapabilities object, customize the format selection algorithm by specifying a GLCapabilitiesChooser, share textures and display lists with other GLDrawables, and specify the display device on which the GLAutoDrawable will be created (GLCanvas and GLWindow only).

A GLCapabilities object specifies the OpenGL parameters for a newly-created widget, such as the color, alpha,, z-buffer and accumulation buffer bit depths and whether the widget is double-buffered. The default capabilities are loosely specified but provide for truecolor RGB, a reasonably large depth buffer, double-buffered, with no alpha, stencil, or accumulation buffers.

An application can override the default pixel format selection algorithm by providing a GLCapabilitiesChooser to the GLCanvas or GLJPanel constructor. (Not all platforms support the GLCapabilitiesChooser mechanism, however; it may be ignored, in particular on Mac OS X where pixel format selection is very different than on other platforms.) The chooseCapabilities method will be called with all of the available pixel formats as an array of GLCapabilities objects, as well as the index indicating the window system's recommended choice; it should return an integer index into this array. The DefaultGLCapabilitiesChooser uses the window system's recommendation when it is available, and otherwise attempts to use a platform-independent selection algorithm.

The GLJPanel can be made non-opaque according to Swing's rendering model, so it can act as an overlay to other Swing or Java2D drawing. In order to enable this, set up your GLCapabilities object with a non-zero alpha depth (a common value is 8 bits) and call setOpaque(false) on the GLJPanel once it has been created. Java2D rendering underneath it will then show through areas where OpenGL has produced an alpha value less than 1.0. See the JGears and JRefract demos for examples of how to use this functionality.

Writing a GLEventListener

Applications implement the GLEventListener interface to perform OpenGL drawing via callbacks. When the methods of the GLEventListener are called, the underlying OpenGL context associated with the drawable is already current. The listener fetches the GL object out of the GLAutoDrawable and begins to perform rendering.

The init() method is called when a new OpenGL context is created for the given GLAutoDrawable. Any display lists or textures used during the application's normal rendering loop can be safely initialized in init(). It is important to note that because the underlying AWT window may be destroyed and recreated while using the same GLCanvas and GLEventListener, the GLEventListener's init() method may be called more than once during the lifetime of the application. The init() method should therefore be kept as short as possible and only contain the OpenGL initialization required for the display() method to run properly. It is the responsibility of the application to keep track of how its various OpenGL contexts share display lists, textures and other OpenGL objects so they can be either be reinitialized or so that reinitialization can be skipped when the init() callback is called.

Note also that the GLEventListener should be added to the GLAutoDrawable before the GLAutoDrawable is shown or rendered to for the first time. If this is not done, it is possible that the init() method will not be called on the GLEventListener. JOGL does not maintain internal state to keep track of whether init() has been called on a particular GLEventListener since the last time an OpenGL context was created for that GLAutoDrawable.

The display() method is called to perform per-frame rendering. The reshape() method is called when the drawable has been resized; the default implementation automatically resizes the OpenGL viewport so often it is not necessary to do any work in this method. The displayChanged() method is designed to allow applications to support on-the-fly screen mode switching, but support for this is not yet implemented so the body of this method should remain empty.

It is strongly recommended that applications always refetch the GL object out of the GLAutoDrawable upon each call to the init(), display() and reshape() methods and pass the GL object down on the stack to any drawing routines, as opposed to storing the GL in a field and referencing it from there. The reason is that multithreading issues inherent to the AWT toolkit make it difficult to reason about which threads certain operations are occurring on, and if the GL object is stored in a field it is unfortunately too easy to accidentally make OpenGL calls from a thread that does not have a current context. This will usually cause the application to crash. For more information please see the section on multithreading.

Checking extensions and functions availability

GLBase.isFunctionAvailable(String glFunctionName) and GLBase.isExtensionAvailable(String glExtensionName) allow to check whether OpenGL functions and extensions are available.

Use of NIO buffers

Use com.jogamp.common.nio.Buffers to create any NIO buffer intented to be used by JOGL in order to avoid native ordering and size problems. Jogl does not modify the position of a buffer passed to its methods but such a position affects its behaviour. Direct NIO buffers are faster and should be used when performances are important. Indirect NIO buffers can be used for non critical operations, for example to retrieve the value of an OpenGL constant. Keep in mind that direct NIO buffers are page-aligned and allocated in the native heap (whereas indirect NIO buffers are allocated in Java heap). Use the VM argument "-XX:MaxDirectMemorySize" to increase the maximum size of the direct memory if the creation of direct NIO buffers fails, use the VM argument "-Xmx" to increase the maximum size of Java heap if the creation of undirect NIO buffers fails.

Documentation of C language functions matching with Jogl methods

Jogl documentation often refers to C language functions. You can find the documentation of these functions in OpenGL references pages here.


JOGL has a low memory footprint. It uses direct NIO buffers in order to avoid copying data both in Java heap and in the native heap when calling native functions. JOGL accesses OpenGL through JNI; as a JNI call only takes a few nanoseconds, it does not drive programs using JOGL noticeably slower than their C/C++ equivalents.

Using the Composable Pipeline

Jogl supports the "composable pipeline" paradigm introduced by the Magician Java binding for OpenGL. The DebugGL pipeline calls glGetError after each OpenGL call, reporting any errors found. It can greatly speed up development time because of its fine-grained error checking as opposed to the manual error checking usually required in OpenGL programs written in C. The TraceGL prints logging information upon each OpenGL call and is helpful when an application crash makes it difficult to see where the error occurred.

To use these pipelines, call GLAutoDrawable.setGL at the beginning of the init method in your GLEventListener. For example,

class MyListener implements GLEventListener {
  public void init(GLDrawable drawable) {
    drawable.setGL(new DebugGL(drawable.getGL()));
    // ...

  // ...

Note that the GLAutoDrawable.setGL() method simply calls setGL() on the default OpenGL context created by the GLAutoDrawable, so sophisticated applications creating their own OpenGL contexts can use the composable pipeline with these contexts by setting the GL object in the context object itself. The composable pipeline needs to be re-installed every time GLContext.makeCurrent() returns CONTEXT_CURRENT_NEW.

N.B: DebugGL and TraceGL have been splitted into several classes matching with all GL subclasses.

if (drawable.getGL().isGL4bc()) {
    final GL4bc gl4bc = drawable.getGL().getGL4bc();
    drawable.setGL(new DebugGL4bc(gl4bc));
else {
    if (drawable.getGL().isGL4()) {
        final GL4 gl4 = drawable.getGL().getGL4();
        drawable.setGL(new DebugGL4(gl4));
    else {
          if (drawable.getGL().isGL3bc()) {
              final GL3bc gl3bc = drawable.getGL().getGL3bc();
              drawable.setGL(new DebugGL3bc(gl3bc));
          else {
              if (drawable.getGL().isGL3()) {
                  final GL3 gl3 = drawable.getGL().getGL3();
                  drawable.setGL(new DebugGL3(gl3));
              else {
                  if (drawable.getGL().isGL2()) {
                      final GL2 gl2 = drawable.getGL().getGL2();
                      drawable.setGL(new DebugGL2(gl2));

Heavyweight and Lightweight Issues

As mentioned above, JOGL supplies both a heavyweight (GLCanvas) and a lightweight (GLJPanel) widget to be able to provide the fastest possible performance for applications which need it as well as 100% correct Swing integration, again for applications which need it. The GLCanvas usually provides higher performance than the GLJPanel, though in recent releases the GLJPanel's speed has been improved when the Java2D/OpenGL pipeline is active as described in this forum discussion. Nonetheless, the GLCanvas can be used in almost every kind of application except those using JInternalFrames. Please see the Swing Connection article mentioned above for details on mixing heavyweight and lightweight widgets. A couple of common pitfalls are described here.

When using JPopupMenus or Swing tool tips in conjunction with the GLCanvas, it is necessary to disable the use of lightweight widgets for the popups. See the methods ToolTipManager.setLightWeightPopupEnabled, JPopupMenu.setLightWeightPopupEnabled, and JPopupMenu.setDefaultLightWeightPopupEnabled.

There are occasionally problems with certain LayoutManagers and component configurations where if a GLCanvas is placed in the middle of a set of lightweight widgets then it may only grow and never shrink. These issues are documented somewhat in JOGL Issue 135 and most recently in the thread "Resize behaviour" in the JOGL forum. The root cause is behavior of the Canvas, and in particular its ComponentPeer. The implementation of getPreferredSize() calls getMinimumSize() and getMinimumSize() turns around and calls Component.getSize(). This effectively means that the Canvas will report its preferred size as being as large as the component has ever been. For some layout managers this doesn't seem to matter, but for others like the BoxLayout it does. See the test case attached to Issue 135 for an example. Replacing the GLCanvas with an ordinary Canvas yields the same behavior.

One suggestion was to override getPreferredSize() so that if a preferred size has not been set by the user, to default to (0, 0). This works fine for some test cases but breaks all of the other JOGL demos because they use a different LayoutManager. There appear to be a lot of interactions between heavyweight vs. lightweight widgets and layout managers. One experiment which was done was to override setSize() in GLCanvas to update the preferred size. This works down to the size specified by the user; if the window is resized any smeller the same problem appears. If reshape() (the base routine of setSize(), setBounds(), etc.) is changed to do the same thing, the demo breaks in the same way it originally did. Therefore this solution is fragile because it isn't clear which of these methods are used internally by the AWT and for what purposes.

There are two possible solutions, both application-specific. The best and most portable appears to be to put the GLCanvas into a JPanel and set the JPanel's preferred size to (0, 0). The JPanel will cause this constraint to be enforced on its contained GLCanvas. The other workaround is to call setPreferredSize(new Dimension(0, 0)) on a newly-created GLCanvas; this method is new in 1.5.

Another issue that occasionally arises on Windows is flickering during live resizing of a GLCanvas. This is caused by the AWT's repainting the background of the Canvas and can not be overridden on a per-Canvas basis, for example when subclassing Canvas into GLCanvas. The repainting of the background of Canvases on Windows can be disabled by specifying the system property -Dsun.awt.noerasebackground=true. Whether to specify this flag depends on the application and should not be done universally, but instead on a case-by-case basis. Some more detail is in the thread "TIP: JOGL + Swing flicker" in the JOGL forum.

SWT/AWT issues

The AWT GLCanvas has to be created once the size of the frame that contains it is no more zero. It is highly advised to do it inside a component listener so that it is called when the frame is resized. This listener has to be immediately removed after the creation of the canvas. Laying out the frame (by calling doLayout()) before starting the animator (or calling display()) is necessary because the width of the canvas cannot be equal to zero and the SWT/AWT helper returns AWT frames with a strange behavior (width and height equal to zero, lazy layout and validation).

AWT Multithreading Issues

Below statements incorrect!

Jogl was designed to interoperate with the AWT, an inherently multithreaded GUI toolkit. OpenGL, in contrast, was originally designed in single-threaded C programming environments. For this reason Jogl provides a framework in which it is possible to write correct multithreaded OpenGL applications using the GLEventListener paradigm.

If an application written using Jogl interacts in any way with the mouse or keyboard, the AWT is processing these events and the multithreaded aspects of the program must be considered.

OpenGL applications usually behave in one of two ways: either they repaint only on demand, for example when mouse input comes in, or they repaint continually, regardless of whether user input is coming in. In the repaint-on-demand model, the application can merely call GLAutoDrawable.display() manually at the end of the mouse or keyboard listener to cause repainting to be done. Alternatively if the application knows the concrete type of the GLDrawable it can call repaint() to have the painting scheduled for a later time.

In the continuous repaint model, the application typically has a main loop which is calling GLAutoDrawable.display() repeatedly, or is using the Animator class, which does this internally. In both of these cases the OpenGL rendering will be done on this thread rather than the internal AWT event queue thread which dispatches mouse and keyboard events.

Both of these models (repaint-on-demand and repaint continually) still require the user to think about which thread keyboard and mouse events are coming in on, and which thread is performing the OpenGL rendering. OpenGL rendering may not occur directly inside the mouse or keyboard handlers, because the OpenGL context for the drawable is not current at this point (hence the warning about storing a GL object in a field, where it can be fetched and accidentally used by another thread). However, a mouse or keyboard listener may invoke GLAutoDrawable.display().

It is generally recommended that applications perform as little work as possible inside their mouse and keyboard handlers to keep the GUI responsive. However, since OpenGL commands can not be run from directly within the mouse or keyboard event listener, the best practice is to store off state when the listener is entered and retrieve this state during the next call to GLEventListener.display().

Furthermore, it is recommended that if there are long computational sequences in the GLEventListener's display method which reference variables which may be being simultaneously modified by the AWT thread (mouse and keyboard listeners) that copies of these variables be made upon entry to display and these copies be referenced throughout display() and the methods it calls. This will prevent the values from changing while the OpenGL rendering is being performed. Errors of this kind show up in many ways, including certain kinds of flickering of the rendered image as certain pieces of objects are rendered in one place and other pieces are rendered elsewhere in the scene. Restructuring the display() method as described has solved all instances of this kind of error that have been seen with Jogl to date.

Prior to Jogl 1.1 b10, the Jogl library attempted to give applications strict control over which thread or threads performed OpenGL rendering. The setRenderingThread(), setNoAutoRedrawMode() and display() APIs were originally designed to allow the application to create its own animation thread and avoid OpenGL context switching on platforms that supported it. Unfortunately, serious stability issues caused by multithreading bugs in either vendors' OpenGL drivers or in the Java platform implementation have arisen on three of Jogl's major supported platforms: Windows, Linux and Mac OS X. In order to address these bugs, the threading model in Jogl 1.1 b10 and later has changed.

All GLEventListener callbacks and other internal OpenGL context management are now performed on one thread. (In the current implementation, this thread is the AWT event queue thread, which is a thread internal to the implementation of the AWT and which is always present when the AWT is being used. Future versions of Jogl may change the thread on which the OpenGL work is performed.) When the GLAutoDrawable.display() method is called from user code, it now performs the work synchronously on the AWT event queue thread, even if the calling thread is a different thread. The setRenderingThread() optimization is now a no-op. The setNoAutoRedrawMode() API still works as previously advertised, though now that all work is done on the AWT event queue thread it no longer needs to be used in most cases. (It was previously useful for working around certain kinds of OpenGL driver bugs.)

Most applications will not see a change in behavior from this change in the Jogl implementation. Applications which use thread-local storage or complex multithreading and synchronization may see a change in their control flow requiring code changes. While it is strongly recommended to change such applications to work under the new threading model, the old threading model can be used by specifying the system property -Djogl.1thread=auto or -Djogl.1thread=false. The "auto" setting is equivalent to the behavior in 1.1 b09 and before, where on ATI cards the single-threaded mode would be used. The "false" setting is equivalent to disabling the single-threaded mode. "true" is now the default setting.

In the APIs the single-threaded behavior continues to be the default and the setRenderingThread() and setNoAutoRedrawMode() APIs have been removed. The public Threading class still provides some control over the internal use of threads in the library as well as external access to these mechanisms.


Jogl exposes hardware-accelerated offscreen rendering (pbuffers) with a minimal and platform-agnostic API. Several recent demos have been successfully ported from C/C++ to Java using Jogl's pbuffer APIs. However, the pbuffer support in Jogl remains one of the more experimental aspects of the package and the APIs may need to change in the future.

To create a pbuffer, call GLDrawableFactory.createGLPbuffer(). It is wise to call GLDrawableFactory.canCreateGLPbuffer() first to ensure the graphics card has pbuffer support first. The pbuffer is created immediately and is available for rendering as soon as createGLPbuffer returns.

A pbuffer is used in conjunction with the GLEventListener mechanism by calling its display() method. Rendering, as always, occurs while the pbuffer's OpenGL context is current. There are render-to-texture options that can be specified in the GLCapabilities for the pbuffer which can make it easier to operate upon the resulting pixels. These APIs are however highly experimental and not yet implemented on all platforms.


Jogl contains support for the GLU (OpenGL Utility Library) version 1.3. Jogl originally supported GLU by wrapping the C version of the APIs, but over time, and thanks to the contributions of several individuals, it now uses a pure-Java version of SGI's GLU library. The pure Java port is enabled by default, and addresses stability issues on certain Linux distributions as well as the lack of native GLU 1.3 support on the Windows platform. In case of problems with the Java port, the C version of the GLU library may be used by specifying the system property -Djogl.glu.nojava on the command line. All of the same functionality is exposed with both the Java and C versions of the GLU library; currently NURBS support is the only missing feature on both sides. If you run into problems with the Java port of the GLU library please file a bug using the Issue Tracker on the Jogl home page.

To use the GLU, simply instantiate a GLU object via new GLU() at the beginning of your program. The methods on the GLU object may be called at any point when an OpenGL context is current. Because the GLU implementation is not thread-safe, one GLU object should be created for each GLEventListener or other entity performing OpenGL rendering in a given thread.

N.B: Some GLU features are only implemented in the subclass GLUgl2.

More Resources

Our Wiki pages, have a look at the Jogl Tutorial resource listing.

The JOGL forum is the best place to ask questions about the library. Many users, as well as the Jogl developers, read this forum frequently, and the archived threads contain a lot of useful information (which still needs to be distilled into documentation).

The JOGL demos provide several examples of usage of the library.

Pepijn Van Eeckhoudt, Kevin Duling and Abdul Bezrati have done JOGL ports of many of the the NeHe demos. These are small examples of various pieces of OpenGL functionality. See also the NeHe web site.

Platform Notes

All Platforms

The following issues, among others, are outstanding on all platforms:

  • A few remaining stability issues, mostly on older graphics cards.


For correct operation, it is necessary to specify the system property -Dsun.java2d.noddraw=true when running JOGL applications on Windows; this system property disables the use of DirectDraw by Java2D. There are driver-level incompatibilities between DirectDraw and OpenGL which manifest themselves as application crashes, poor performance, bad flickering, and other artifacts. This poor behavior may exhibit itself when OpenGL and DirectDraw are simply used in the same application, not even just in the same window, so disabling Java2D's DirectDraw pipeline and forcing it to use its GDI pipeline is the only way to work around these issues. Java Web Start applications may set this system property by adding the following line to the <resources> section of the JNLP file: <property name="sun.java2d.noddraw" value="true"/>

X11 Platforms (Linux, Solaris, ..)

Mac OS X

The following issues remain with the Mac OS X port:
  • Due to the mechanism by which the Cocoa graphics system selects OpenGL pixel formats, the GLCapabilitiesChooser mechanism can not be implemented on Mac OS X as on other platforms. Currently the underlying Cocoa pixel format selection is used on an NSOpenGLPixelFormat derived from the settings in the GLCapabilities, and the GLCapabilitiesChooser is ignored.
