I meet this problem even on Win2000 system. The wierd part is same code works fine before and all in a sudden, it throw out nullPointerException. I used following code to initialize the Canvas3D,
GraphicsConfiguration config = SimpleUniverse.getPreferredConfiguration(); c = new Canvas3D(config); it works on most windows system, but can not run on the one I mentioned. Does anyone have ideas what may cause the problem? =========================================================================== To unsubscribe, send email to [EMAIL PROTECTED] and include in the body of the message "signoff JAVA3D-INTEREST".
