+/** A higher-level abstraction than {@link GLDrawable} which supplies
+ an event based mechanism ({@link GLEventListener}) for performing
+ OpenGL rendering. A GLAutoDrawable automatically creates a primary
+ rendering context which is associated with the GLAutoDrawable for
+ the lifetime of the object.
+ <p>
+ Since the {@link GLContext} {@link GLContext#makeCurrent makeCurrent}
+ implementation is synchronized, i.e. blocks if the context
+ is current on another thread, the internal
+ {@link GLContext} for the GLAutoDrawable can be used for the event
+ based rendering mechanism and by end users directly.
+ </p>
+ <h5><a name="initialization">GLAutoDrawable Initialization</a></h5>
+ <p>
+ The implementation shall initialize itself as soon as possible,
+ which is only possible <i>after</i> the attached {@link com.jogamp.nativewindow.NativeSurface NativeSurface} becomes visible and and is realized.<br>
+ The following initialization sequence should be implemented:
+ <ul>
+ <li> Create the {@link GLDrawable} with the requested {@link GLCapabilities}</li>
+ <li> Notify {@link GLDrawable} to validate the {@link GLCapabilities} by calling {@link GLDrawable#setRealized setRealized(true)}.</li>
+ <li> Create the new {@link GLContext}.</li>
+ <li> Initialize all OpenGL resources by calling {@link GLEventListener#init init(..)} for all
+ registered {@link GLEventListener}s. This can be done immediately, or with the followup {@link #display display(..)} call.</li>
+ <li> Send a reshape event by calling {@link GLEventListener#reshape reshape(..)} for all
+ registered {@link GLEventListener}s. This shall be done after the {@link GLEventListener#init init(..)} calls.</li>
+ </ul>
+ Note: The last to {@link GLEventListener} actions shall be also performed, when {@link #addGLEventListener(GLEventListener) adding}
+ a new one to an already initialized {@link GLAutoDrawable}.
+ </p>
+ <h5><a name="reconfiguration">GLAutoDrawable Reconfiguration</a></h5>
+ <p>
+ Another implementation detail is the {@link GLDrawable} reconfiguration. One use case is where a window is being
+ dragged to another screen with a different pixel configuration, ie {@link GLCapabilities}. The implementation
+ shall be able to detect such cases in conjunction with the associated {@link com.jogamp.nativewindow.NativeSurface NativeSurface}.<br/>
+ For example, AWT's {@link java.awt.Canvas} 's {@link java.awt.Canvas#getGraphicsConfiguration getGraphicsConfiguration()}
+ is capable to determine a display device change. This is demonstrated within {@link com.jogamp.opengl.awt.GLCanvas}'s
+ and NEWT's <code>AWTCanvas</code> {@link com.jogamp.opengl.awt.GLCanvas#getGraphicsConfiguration getGraphicsConfiguration()}
+ specialization. Another demonstration is NEWT's {@link com.jogamp.nativewindow.NativeWindow NativeWindow}
+ implementation on the Windows platform, which utilizes the native platform's <i>MonitorFromWindow(HWND)</i> function.<br/>
+ All OpenGL resources shall be regenerated, while the drawable's {@link GLCapabilities} has
+ to be chosen again. The following protocol shall be satisfied.
+ <ul>
+ <li> Controlled disposal:</li>
+ <ul>
+ <li> Dispose all OpenGL resources by calling {@link GLEventListener#dispose dispose(..)} for all
+ registered {@link GLEventListener}s.</li>
+ <li> Destroy the {@link GLContext}.</li>
+ <li> Notify {@link GLDrawable} of the invalid state by calling {@link GLDrawable#setRealized setRealized(false)}.</li>
+ </ul>
+ <li> Controlled regeneration:</li>
+ <ul>
+ <li> Create the new {@link GLDrawable} with the requested {@link GLCapabilities}
+ <li> Notify {@link GLDrawable} to revalidate the {@link GLCapabilities} by calling {@link GLDrawable#setRealized setRealized(true)}.</li>
+ <li> Create the new {@link GLContext}.</li>
+ <li> Initialize all OpenGL resources by calling {@link GLEventListener#init init(..)} for all
+ registered {@link GLEventListener}s. This can be done immediatly, or with the followup {@link #display display(..)} call.</li>
+ <li> Send a reshape event by calling {@link GLEventListener#reshape reshape(..)} for all
+ registered {@link GLEventListener}s. This shall be done after the {@link GLEventListener#init init(..)} calls.</li>
+ </ul>
+ </ul>
+ Note: Current graphics driver keep the surface configuration for a given window, even if the window is moved to
+ a monitor with a different pixel configuration, ie 32bpp to 16bpp. However, it is best to not assume such behavior
+ and make your application comply with the above protocol.
+ <p>
+ Avoiding breakage with older applications and because of the situation
+ mentioned above, the <code>boolean</code> system property <code>jogl.screenchange.action</code> will control the
+ screen change action as follows:<br/>
+ <PRE>
+ -Djogl.screenchange.action=false Disable the {@link GLDrawable} reconfiguration (the default)
+ -Djogl.screenchange.action=true Enable the {@link GLDrawable} reconfiguration
+ </PRE>
+ </p>
+ <h5><a name="locking">GLAutoDrawable Locking</a></h5>
+ GLAutoDrawable implementations perform locking in the following order:
+ <ol>
+ <li> {@link #getUpstreamLock()}.{@link RecursiveLock#lock() lock()}</li>
+ <li> {@link #getNativeSurface()}.{@link NativeSurface#lockSurface() lockSurface()} </li>
+ </ol>
+ and releases the locks accordingly:
+ <ol>
+ <li> {@link #getNativeSurface()}.{@link NativeSurface#unlockSurface() unlockSurface()} </li>
+ <li> {@link #getUpstreamLock()}.{@link RecursiveLock#unlock() unlock()}</li>
+ </ol>
+ Above <i>locking order</i> is mandatory to guarantee
+ atomicity of operation and to avoid race-conditions.
+ A custom implementation or user applications requiring exclusive access
+ shall follow the <i>locking order</i>.
+ See:
+ <ul>
+ <li>{@link #getUpstreamLock()}</li>
+ <li>{@link #invoke(boolean, GLRunnable)}</li>
+ <li>{@link #invoke(boolean, List)}</li>

+/** Abstraction for an OpenGL rendering context. In order to perform

+ thread. OpenGL rendering semantics specify that only one context
+ may be current on the current thread at any given time, and also
+ that a given context may be current on only one thread at any
+ given time. Because components can be added to and removed from
+ the component hierarchy at any time, it is possible that the
+ underlying OpenGL context may need to be destroyed and recreated
+ multiple times over the lifetime of a given component. This

+ * particular component is intended to be similarly persistent. A
+ * <CODE>GLDrawable</CODE> is intended to be created for a given
+ * component when it is constructed and live as long as that

+/** <p> Provides a virtual machine- and operating system-independent
+ mechanism for creating {@link GLDrawable}s.
+ </p>
+ <p> The {@link com.jogamp.opengl.GLCapabilities} objects passed
+ in to the various factory methods are used as a hint for the
+ properties of the returned drawable. The default capabilities
+ selection algorithm (equivalent to passing in a null {@link
+ GLCapabilitiesChooser}) is described in {@link
+ DefaultGLCapabilitiesChooser}. Sophisticated applications needing
+ to change the selection algorithm may pass in their own {@link
+ GLCapabilitiesChooser} which can select from the available pixel
+ formats. The GLCapabilitiesChooser mechanism may not be supported
+ by all implementations or on all platforms, in which case any
+ passed GLCapabilitiesChooser will be ignored.
+ </p>
+
+ <p> Because of the multithreaded nature of the Java platform's
+ Abstract Window Toolkit, it is typically not possible to immediately
+ reject a given {@link GLCapabilities} as being unsupportable by
+ either returning <code>null</code> from the creation routines or
+ raising a {@link GLException}. The semantics of the rejection
+ process are (unfortunately) left unspecified for now. The current
+ implementation will cause a {@link GLException} to be raised
+ during the first repaint of the {@link com.jogamp.opengl.awt.GLCanvas} or {@link
+ com.jogamp.opengl.awt.GLJPanel} if the capabilities can not be met.<br>
+ {@link GLOffscreenAutoDrawable} are created lazily,
+ see {@link #createOffscreenAutoDrawable(AbstractGraphicsDevice, GLCapabilitiesImmutable, GLCapabilitiesChooser, int, int) createOffscreenAutoDrawable(..)}.
+ </p>

+ <p> The concrete GLDrawableFactory subclass instantiated by {@link
+ #getFactory getFactory} can be changed by setting the system
+ property <code>opengl.factory.class.name</code> to the
+ fully-qualified name of the desired class.

+ * It would be possible to implement double buffering simply using

+/**
+ * Adds capabilities to set a shared {@link GLContext} directly or via an {@link GLAutoDrawable}.
+ * <p>
+ * Sharing of server-side OpenGL objects such as buffer objects, e.g. VBOs,
+ * and textures among OpenGL contexts is supported with this interface.
+ * </p>
+ * <p>
+ * A <i>master</i> {@link GLContext} is the {@link GLContext} which is created first.
+ * Subsequent shared {@link GLContext} w/ the <i>master</i> are referred as <i>slave</i> {@link GLContext}.
+ * </p>
+ * <p>
+ * Implementations of this interface control the <i>slave's</i> {@link GLContext} and {@link GLAutoDrawable} realization,
+ * i.e. the <i>slave</i> {@link GLAutoDrawable} will not be realized before their associated <i>master</i>.
+ * </p>
+ * <p>
+ * Using the nearest or same {@link GLCapabilitiesImmutable#getVisualID(com.jogamp.nativewindow.VisualIDHolder.VIDType) visual ID}
+ * or {@link GLCapabilitiesImmutable caps} across the shared {@link GLDrawable}s will yield best compatibility.
+ * </p>
+ * <h5><a name="lifecycle">Lifecycle Considerations</a></h5>
+ * <p>
+ * After shared objects are created on the <i>master</i>, the OpenGL pipeline
+ * might need to be synchronized w/ the <i>slaves</i>, e.g. via {@link GL#glFinish()}.
+ * At least this has been experienced w/ OSX 10.9.
+ * </p>
+ * <p>
+ * In general, destroying a <i>master</i> {@link GLContext} before their shared <i>slaves</i>
+ * shall be permissible, i.e. the OpenGL driver needs to handle pending destruction of shared resources.
+ * This is confirmed to work properly on most platform/driver combinations,
+ * see unit test <code>com.jogamp.opengl.test.junit.jogl.acore.TestSharedContextVBOES2NEWT3</code> and similar.
+ * </p>
+ * <p>
+ * However, to avoid scenarios with buggy drivers, users <i>may not</i> destroy the
+ * <i>master</i> {@link GLContext} before its shared <i>slave</i> {@link GLContext} instances
+ * <i>as long as they are using them</i>.<br>
+ * Otherwise the OpenGL driver may crash w/ SIGSEGV, due to using already destroyed shared resources,
+ * if not handling the pending destruction of the latter!<br>
+ * Either proper lifecycle synchronization is implemented, e.g. by notifying the <i>slaves</i> about the loss of the shared resources,
+ * <i>or</i> the <i>slaves</i> validate whether the resources are still valid.
+ * </p>
+ * <p>
+ * To simplify above lifecycle issues, one may use a {@link GLDrawableFactory#createDummyDrawable(com.jogamp.nativewindow.AbstractGraphicsDevice, boolean, GLCapabilitiesImmutable, GLCapabilitiesChooser) dummy}
+ * {@link GLDrawable} and it's {@link GLContext} as the <i>master</i> of all shared <i>slave</i> {@link GLContext}.
+ * Since this <i>dummy instance</i> does not depend on any native windowing system, it can be controlled easily w/o being <i>in sight</i>.<br>
+ * Below code creates a {@link GLAutoDrawable} based on a <i>dummy GLDrawable</i>:
+ * <pre>
+ // GLProfile and GLCapabilities should be equal across all shared GL drawable/context.
+ final GLCapabilitiesImmutable caps = ... ;
+ final GLProfile glp = caps.getGLProfile();
+ ..
+ final boolean createNewDevice = true; // use 'own' display device!
+ final GLAutoDrawable sharedDrawable = GLDrawableFactory.getFactory(glp).createDummyAutoDrawable(null, createNewDevice, caps, null);
+ sharedDrawable.display(); // triggers GLContext object creation and native realization.
+ ...
+ // Later a shared 'slave' can be created e.g.:
+ GLWindow glad = GLWindow.create(caps); // or any other GLAutoDrawable supporting GLSharedContextSetter
+ glad.setSharedAutoDrawable(sharedDrawable);
+ glad.addGLEventListener(..);
+ glad.setVisible(true); // GLWindow creation ..
+ * </pre>
+ * </p>
+ * <h5><a name="synchronization">GL Object Synchronization</a></h5>
+ * <p>
+ * Usually synchronization of shared GL objects should not be required, if the shared GL objects
+ * are created and immutable before concurrent usage.
+ * </p>
+ * <p>
+ * However, using drivers exposing {@link GLRendererQuirks#NeedSharedObjectSync} always
+ * require the user to synchronize access of shared GL objects.
+ * </p>
+ * <p>
+ * Synchronization can be avoided if accessing the shared GL objects
+ * exclusively via a queue or {@link com.jogamp.common.util.Ringbuffer Ringbuffer}, see GLMediaPlayerImpl as an example.
+ * </p>
+ * </p>

+/** This API provides access to the threading model for the implementation of
+ the classes in this package.
+
+ <P>
+
+ OpenGL is specified as a thread-safe API, but in practice there
+ are multithreading-related issues on most, if not all, of the
+ platforms which support it. For example, some OpenGL
+ implementations do not behave well when one context is made
+ current first on one thread, released, and then made current on a
+ second thread, although this is legal according to the OpenGL
+ specification. On other platforms there are other problems.
+
+ <P>
+
+ Due to these limitations, and due to the inherent multithreading
+ in the Java platform (in particular, in the Abstract Window
+ Toolkit), it is often necessary to limit the multithreading
+ occurring in the typical application using the OpenGL API.
+
+ <P>
+
+ In the current reference implementation, for instance, multithreading
+ has been limited by
+ forcing all OpenGL-related work for GLAutoDrawables on to a single
+ thread. In other words, if an application uses only the
+ GLAutoDrawable and GLEventListener callback mechanism, it is
+ guaranteed to have the most correct single-threaded behavior on
+ all platforms.
+
+ <P>
+
+ Applications using the GLContext makeCurrent/release API directly
+ will inherently break this single-threaded model, as these methods
+ require that the OpenGL context be made current on the current
+ thread immediately. For applications wishing to integrate better
+ with an implementation that uses the single-threaded model, this
+ class provides public access to the mechanism used by the implementation.
+
+ <P>
+
+ Users can execute Runnables on the
+ internal thread used for performing OpenGL work, and query whether
+ the current thread is already this thread. Using these mechanisms
+ the user can move work from the current thread on to the internal
+ OpenGL thread if desired.
+
+ <P>
+
+ This class also provides mechanisms for querying whether this
+ internal serialization of OpenGL work is in effect, and a
+ programmatic way of disabling it. In the current reference
+ implementation it is enabled by default, although it could be
+ disabled in the future if OpenGL drivers become more robust on
+ all platforms.
+
+ <P>
+
+ In addition to specifying programmatically whether the single
+ thread for OpenGL work is enabled, users may switch it on and off
+ using the system property <code>jogl.1thread</code>. Valid values
+ for this system property are:
+
+ <PRE>
+ -Djogl.1thread=false Disable single-threading of OpenGL work, hence use multithreading.
+ -Djogl.1thread=true Enable single-threading of OpenGL work (default -- on a newly-created worker thread)
+ -Djogl.1thread=auto Select default single-threading behavior (currently on)
+ -Djogl.1thread=awt Enable single-threading of OpenGL work on AWT event dispatch thread (current default on all
+ platforms, and also the default behavior older releases)
+ -Djogl.1thread=worker Enable single-threading of OpenGL work on newly-created worker thread (not suitable for Mac
+ OS X or X11 platforms, and risky on Windows in applet environments)
+ </PRE>

+/** A lightweight Swing component which provides OpenGL rendering
+ support. Provided for compatibility with Swing user interfaces
+ when adding a heavyweight doesn't work either because of
+ Z-ordering or LayoutManager problems.
+ <p>
+ The GLJPanel can be made transparent by creating it with a
+ GLCapabilities object with alpha bits specified and calling {@link
+ #setOpaque}(false). Pixels with resulting OpenGL alpha values less
+ than 1.0 will be overlaid on any underlying Swing rendering.
+ </p>
+ <p>
+ This component attempts to use hardware-accelerated rendering via FBO or pbuffers and
+ falls back on to software rendering if none of the former are available
+ using {@link GLDrawableFactory#createOffscreenDrawable(AbstractGraphicsDevice, GLCapabilitiesImmutable, GLCapabilitiesChooser, int, int) GLDrawableFactory.createOffscreenDrawable(..)}.<br/>
+ </p>
+ <p>
+ <a name="verticalFlip">A vertical-flip is required</a>, if the drawable {@link #isGLOriented()} and {@link #setSkipGLOrientationVerticalFlip(boolean) vertical flip is not skipped}.<br>
+ In this case this component performs the required vertical flip to bring the content from OpenGL's orientation into AWT's orientation.<br>
+ In case <a href="#fboGLSLVerticalFlip">GLSL based vertical-flip</a> is not available,
+ the CPU intensive {@link System#arraycopy(Object, int, Object, int, int) System.arraycopy(..)} is used line by line.
+ See details about <a href="#fboGLSLVerticalFlip">FBO and GLSL vertical flipping</a>.
+ </p>
+ <p>
+ For performance reasons, as well as for <a href="#bug842">GL state sideeffects</a>,
+ <b>{@link #setSkipGLOrientationVerticalFlip(boolean) skipping vertical flip} is highly recommended</b>!
+ </p>
+ <p>
+ The OpenGL path is concluded by copying the rendered pixels an {@link BufferedImage} via {@link GL#glReadPixels(int, int, int, int, int, int, java.nio.Buffer) glReadPixels(..)}
+ for later Java2D composition.
+ </p>
+ <p>
+ Finally the Java2D compositioning takes place via via {@link Graphics#drawImage(java.awt.Image, int, int, int, int, java.awt.image.ImageObserver) Graphics.drawImage(...)}
+ on the prepared {@link BufferedImage} as described above.
+ </p>
+ <P>
+ * Please read <a href="GLCanvas.html#java2dgl">Java2D OpenGL Remarks</a>.
+ * </P>
+ *
+ <a name="fboGLSLVerticalFlip"><h5>FBO / GLSL Vertical Flip</h5></a>
+ If <a href="#verticalFlip">vertical flip is required</a>,
+ FBO is used, GLSL is available and {@link #setSkipGLOrientationVerticalFlip(boolean) vertical flip is not skipped}, a fragment shader is utilized
+ to flip the FBO texture vertically. This hardware-accelerated step can be disabled via system property <code>jogl.gljpanel.noglsl</code>.
+ <p>
+ The FBO / GLSL code path uses one texture-unit and binds the FBO texture to it's active texture-target,
+ see {@link #setTextureUnit(int)} and {@link #getTextureUnit()}.
+ </p>
+ <p>
+ The active and dedicated texture-unit's {@link GL#GL_TEXTURE_2D} state is preserved via {@link TextureState}.
+ See also {@link Texture#textureCallOrder Order of Texture Commands}.
+ </p>
+ <p>
+ The current gl-viewport is preserved.
+ </p>
+ <p>
+ <a name="bug842"><i>Warning (Bug 842)</i></a>: Certain GL states other than viewport and texture (see above)
+ influencing rendering, will also influence the GLSL vertical flip, e.g. {@link GL#glFrontFace(int) glFrontFace}({@link GL#GL_CCW}).
+ It is recommended to reset those states to default when leaving the {@link GLEventListener#display(GLAutoDrawable)} method!
+ We may change this behavior in the future, i.e. preserve all influencing states.
+ </p>

+ <a name="contextSharing"><h5>OpenGL Context Sharing</h5></a>

+ * The <b>combine</b> callback method is called to create a new vertex when
+ * the tessellation detects an intersection, or wishes to merge features. The
+ * method takes four arguments: an array of three elements each of type
+ * double, an array of four references, an array of four elements each of
+ * type float, and a reference to a reference.<P>
+ *
+ * The vertex is defined as a linear combination of up to four existing
+ * vertices, stored in <i>data</i>. The coefficients of the linear combination
+ * are given by <i>weight</i>; these weights always add up to 1. All vertex
+ * pointers are valid even when some of the weights are 0. <i>coords</i> gives
+ * the location of the new vertex.<P>
+ *
+ * The user must allocate another vertex, interpolate parameters using
+ * <i>data</i> and <i>weight</i>, and return the new vertex pointer in
+ * <i>outData</i>. This handle is supplied during rendering callbacks. The
+ * user is responsible for freeing the memory some time after
+ * {@link GLU#gluTessEndPolygon gluTessEndPolygon} is
+ * called.<P>
+ *
+ * For example, if the polygon lies in an arbitrary plane in 3-space, and a
+ * color is associated with each vertex, the <b>GLU_TESS_COMBINE</b>
+ * callback might look like this:
+ * </UL>
