-/** 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>
- <p>
- <a name="contextSharing"><h5>OpenGL Context Sharing</h5></a>
- To share a {@link GLContext} see the following note in the documentation overview:
- <a href="../../../../overview-summary.html#SHARING">context sharing</a>
- as well as {@link GLSharedContextSetter}.
