Subject: Null GraphicsConfiguration From: Zak Nixon <[EMAIL PROTECTED]> Date: Sat, 14 Dec 2002 22:53:12 -0500 I tried running the code: SimpleUniverse.getPreferredConfiguration() on a Windows 2000 machine and everything worked fine. I 'upgraded' to Windows XP and now I get this error. I am using a Matrox Millennium G400 DualHead MAX, with updated drivers from the website. Can anyone help me? Thanks Zak
On both of the computers in our lab with G400 graphics cards, I had to enable the 'Use 32-bit Z-buffering' option. Otherwise the somewhere along the line the driver and Java3D become convinced that the card cannot support the default graphics configuration template. Can someone add this to the faq, please: Q: I have a Matrox G4XX card, and I get null graphics configuration errors when trying to use SimpleUniverse. Also applicable if you are getting a null pointer exception immediately after the warning concerning creating a Canvas3D with a null GraphicsConfiguration. A: Welcome to the joys of sample code becoming a de facto standard. Enable the 'Use 32-bit Z-buffering' option for your graphics card because the default graphics configuration template asks for approximately 16-bit Z buffering and the card is supplying less than that (approximately 12-bit or so). --Brad Vender =========================================================================== To unsubscribe, send email to [EMAIL PROTECTED] and include in the body of the message "signoff JAVA3D-INTEREST".
