Method Detail

chooseGraphicsConfiguration

public AbstractGraphicsConfiguration chooseGraphicsConfiguration(GLCapabilities capabilities,
                                                        GLCapabilitiesChooser chooser,
                                                        AbstractGraphicsDevice absDevice)

Description copied from class: GLDrawableFactory

Selects a graphics configuration on the specified graphics device compatible with the supplied GLCapabilities. This method is intended to be used by applications which do not use the supplied GLCanvas class but instead wrap their own Canvas or other window toolkit-specific object with a GLDrawable. Some platforms (specifically X11) require the graphics configuration to be specified when the window toolkit object is created. This method may return null on platforms on which the OpenGL pixel format selection process is performed later.

The concrete data type of the passed graphics device and returned graphics configuration must be specified in the documentation binding this particular API to the underlying window toolkit. The Reference Implementation accepts AWTGraphicsDevice objects and returns AWTGraphicsConfiguration objects.

Specified by:

chooseGraphicsConfiguration in class GLDrawableFactory

getGLDrawable

public GLDrawable getGLDrawable(Object target,
                       GLCapabilities capabilities,
                       GLCapabilitiesChooser chooser)

Description copied from class: GLDrawableFactory

Returns a GLDrawable that wraps a platform-specific window system object, such as an AWT or LCDUI Canvas. On platforms which support it, selects a pixel format compatible with the supplied GLCapabilities, or if the passed GLCapabilities object is null, uses a default set of capabilities. On these platforms, uses either the supplied GLCapabilitiesChooser object, or if the passed GLCapabilitiesChooser object is null, uses a DefaultGLCapabilitiesChooser instance.

getGLDrawable in class GLDrawableFactory

createOffscreenDrawable

public GLDrawableImpl createOffscreenDrawable(GLCapabilities capabilities,
                                     GLCapabilitiesChooser chooser)

Description copied from class: GLDrawableFactoryImpl

Creates a (typically software-accelerated) offscreen GLDrawable used to implement the fallback rendering path of the GLJPanel.

Specified by:

canCreateGLPbuffer

public boolean canCreateGLPbuffer()

Description copied from class: GLDrawableFactory

createGLPbuffer

public GLPbuffer createGLPbuffer(GLCapabilities capabilities,

                        int initialHeight,
                        GLContext shareWith)

Description copied from class: GLDrawableFactory

Creates a GLPbuffer with the given capabilites and dimensions.

See the note in the overview documentation on context sharing.

Specified by:

createGLPbuffer in class GLDrawableFactory

createExternalGLContext

public GLContext createExternalGLContext()

Description copied from class: GLDrawableFactory

Creates a GLContext object representing an existing OpenGL context in an external (third-party) OpenGL-based library. This GLContext object may be used to draw into this preexisting context using its GL and GLU objects. New contexts created through GLDrawables may share textures and display lists with this external context.

The underlying OpenGL context must be current on the current thread at the time this method is called. The user is responsible for the maintenance of the underlying OpenGL context; calls to makeCurrent and release on the returned GLContext object have no effect. If the underlying OpenGL context is destroyed, the destroy method should be called on the GLContext. A new GLContext object should be created for each newly-created underlying OpenGL context.

Specified by:

createExternalGLContext in class GLDrawableFactory

canCreateExternalGLDrawable

public boolean canCreateExternalGLDrawable()

Description copied from class: GLDrawableFactory

Returns true if it is possible to create an external GLDrawable object via GLDrawableFactory.createExternalGLDrawable().

Specified by:

canCreateExternalGLDrawable in class GLDrawableFactory

createExternalGLDrawable

public GLDrawable createExternalGLDrawable()

Description copied from class: GLDrawableFactory

Creates a GLDrawable object representing an existing OpenGL drawable in an external (third-party) OpenGL-based library. This GLDrawable object may be used to create new, fully-functional GLContexts on the OpenGL drawable. This is useful when interoperating with a third-party OpenGL-based library and it is essential to not perturb the state of the library's existing context, even to the point of not sharing textures or display lists with that context.

An underlying OpenGL context must be current on the desired drawable and the current thread at the time this method is called. The user is responsible for the maintenance of the underlying drawable. If one or more contexts are created on the drawable using GLDrawable.createContext(javax.media.opengl.GLContext), and the drawable is deleted by the third-party library, the user is responsible for calling GLContext.destroy() on these contexts.

Calls to setSize, getWidth and getHeight are illegal on the returned GLDrawable. If these operations are required by the user, they must be performed by the third-party library.

It is legal to create both an external GLContext and GLDrawable representing the same third-party OpenGL entities. This can be used, for example, to query current state information using the external GLContext and then create and set up new GLContexts using the external GLDrawable.

This functionality may not be available on all platforms and GLDrawableFactory.canCreateExternalGLDrawable() should be called first to see if it is present. For example, on X11 platforms, this API requires the presence of GLX 1.3 or later.
