public static void	invokeWithOGLContextCurrent(final Graphics g, final Runnable r) Makes current the OpenGL context associated with the passed Graphics object and runs the given Runnable on the Queue Flushing Thread in one atomic action.
public static boolean	invokeWithOGLSharedContextCurrent(final GraphicsConfiguration g, final Runnable r) Makes current the "shared" OpenGL context associated with the given GraphicsConfiguration object, allowing JOGL to share server-side OpenGL objects like textures and display lists with this context when necessary.
public static boolean	isFBOEnabled()
public static boolean	isOGLPipelineActive()
public static boolean	isOGLPipelineResourceCompatible()
public static boolean	isQueueFlusherThread()
public static boolean	makeOGLContextCurrentOnSurface(final Graphics g, final long ctx) (Mac OS X-specific) Makes the given OpenGL context current on the surface associated with the given Graphics object.

createOGLContextOnSurface	back to summary
public static long createOGLContextOnSurface(final Graphics g, final long shareCtx) (Mac OS X-specific) Creates a new OpenGL context on the surface associated with the given Graphics object, sharing textures and display lists with the specified (CGLContextObj) share context.

destroyOGLContext	back to summary
public static void destroyOGLContext(final long ctx) (Mac OS X-specific) Destroys the given OpenGL context.

filterShareContext	back to summary
public static GLContext filterShareContext(final GLContext shareContext) Returns either the given GLContext or a substitute one with which clients should share textures and display lists. Needed when the Java2D/OpenGL pipeline is active and FBOs are being used for rendering. FIXME: may need to alter the API in the future to indicate which GraphicsDevice the source context is associated with.

getOGLScissorBox	back to summary
public static Rectangle getOGLScissorBox(final Graphics g) Returns the OpenGL scissor region associated with the given Graphics object, taking into account all clipping regions, etc. To avoid destroying Java2D's previous rendering results, this method should be called and the resulting rectangle's bounds passed to a call to glScissor(). Should only be called from the Queue Flusher Thread.

getOGLSurfaceIdentifier	back to summary
public static Object getOGLSurfaceIdentifier(final Graphics g) Returns an opaque "surface identifier" associated with the given Graphics object. If this changes from invocation to invocation, the underlying OpenGL drawable for the Graphics object has changed and a new external GLDrawable and GLContext should be created (and the old ones destroyed). Should only be called from the Queue Flusher Thread.

getOGLSurfaceIdentifier

back to summary

public static Object getOGLSurfaceIdentifier(final Graphics g)

Returns an opaque "surface identifier" associated with the given Graphics object. If this changes from invocation to invocation, the underlying OpenGL drawable for the Graphics object has changed and a new external GLDrawable and GLContext should be created (and the old ones destroyed). Should only be called from the Queue Flusher Thread.

getOGLSurfaceType	back to summary
public static int getOGLSurfaceType(final Graphics g) Returns the underlying surface type for the given Graphics object. This indicates, in particular, whether Java2D is currently rendering into a pbuffer or FBO.

getOGLTextureType	back to summary
public static int getOGLTextureType(final Graphics g) Returns the underlying texture target of the given Graphics object assuming it is rendering to an FBO. Returns either GL_TEXTURE_2D or GL_TEXTURE_RECTANGLE_ARB.

getOGLUtilitiesIntField	back to summary
private static int getOGLUtilitiesIntField(final String name)

getOGLViewport	back to summary
public static Rectangle getOGLViewport(final Graphics g, final int componentWidth, final int componentHeight) Returns the OpenGL viewport associated with the given Graphics object, assuming that the Graphics object is associated with a component of the specified width and height. The user should call glViewport() with the returned rectangle's bounds in order to get correct rendering results. Should only be called from the Queue Flusher Thread.

getOGLViewport

back to summary

public static Rectangle getOGLViewport(final Graphics g, final int componentWidth, final int componentHeight)

Returns the OpenGL viewport associated with the given Graphics object, assuming that the Graphics object is associated with a component of the specified width and height. The user should call glViewport() with the returned rectangle's bounds in order to get correct rendering results. Should only be called from the Queue Flusher Thread.

getShareContext	back to summary
public static GLContext getShareContext(final GraphicsDevice device) Returns the GLContext associated with the Java2D "share context", with which all contexts created by JOGL must share textures and display lists when the FBO option is enabled for the Java2D/OpenGL pipeline.

invokeWithOGLContextCurrent	back to summary
public static void invokeWithOGLContextCurrent(final Graphics g, final Runnable r) throws GLException Makes current the OpenGL context associated with the passed Graphics object and runs the given Runnable on the Queue Flushing Thread in one atomic action.

invokeWithOGLSharedContextCurrent	back to summary
public static boolean invokeWithOGLSharedContextCurrent(final GraphicsConfiguration g, final Runnable r) throws GLException Makes current the "shared" OpenGL context associated with the given GraphicsConfiguration object, allowing JOGL to share server-side OpenGL objects like textures and display lists with this context when necessary. This is needed when Java2D's FBO support is enabled, because in order to render into that FBO, JOGL must share textures and display lists with it. Returns false if the passed GraphicsConfiguration was not an OpenGL GraphicsConfiguration.

invokeWithOGLSharedContextCurrent

back to summary

public static boolean invokeWithOGLSharedContextCurrent(final GraphicsConfiguration g, final Runnable r) throws GLException

Makes current the "shared" OpenGL context associated with the given GraphicsConfiguration object, allowing JOGL to share server-side OpenGL objects like textures and display lists with this context when necessary. This is needed when Java2D's FBO support is enabled, because in order to render into that FBO, JOGL must share textures and display lists with it. Returns false if the passed GraphicsConfiguration was not an OpenGL GraphicsConfiguration.
