JOGL 2 and Java 7 support has arrived! Support has also been added for NEWT, which provides high performance OpenGL Canvas implementations for Swing and SWT.
Updating older Glimpse code to Glimpse 2.0.0 will require refactoring due to the move to JOGL 2.0. Further, although SwingGlimpseCanvas and SWTGlimpseCanvas still exist, moving to the new NEWT implementations (NewtSwingGlimpseCanvas and NewtSwtGlimpseCanvas) is highly recommended because of the bug fixes and performance improvements which they provide. See any of the updated Glimpse examples for details.
Those not wishing to upgrade to JOGL 2.0, or requiring a more stable Glimpse release, should continue to use the Glimpse 1.3.3.
