Hey
folks,
I have observed a
strange problem using Java 3D on laptops, and I was wondering if anyone has
seen a similar problem.
Our product is a
Java applet which uses a Java 3D canvas (a 3D view) along with some Swing-based
user interface components (e.g. buttons). On laptops using the ATI RAGE
MOBILITY graphics chipset, the canvas and the UI components will flicker
erratically as the canvas is being repainted. Needless to say, for dynamic
operations such as moving the viewpoint (where the canvas is continuously
refreshed), this can be very distracting.
Also, the problem
doesn't always happen: sometimes it is there, sometimes it is not. It has
not been observed in native OpenGL-based applications, or on machines using
different graphics hardware. We are using the OpenGL version of Java 3D 1.2.1
running on Windows 2000, and the latest ATI RAGE MOBILITY driver (from
Dell, the manufacturer of these laptops).
If you have seen
this problem or know a way to diagnose it or work around it, let me know.
Thanks!
