As far as I remember the ATI-Control-Panels offer a possibility to specify
the texture graphics depth too (or was it for the background only?).

Hi John,
I send you the non-cropped screenshot of my java3d application.
please do not distribue or public. I have a ATI radeon 9000 on
windows 2000. the cards quality settings are at maximum.
4x anti-alaising is activated. the method
GraphicsConfig...getColorModel().getPixelSize();
says 24 bits per pixel in the opengl window. the canvas back-
ground is set to light gray. the texture as a file on my disk has
16.8 million colors (24 bits) and a size of 640x480 pixel.
it looks very nice. do you have any idea?
thank you for your interest
Chris Ender

Chris,
Actually I take that back, it shouldn't be the screen capture as your
spheres are nice and crisp. Thus it appears that however you've mapped
the texture onto the background it may be getting magnified poorly.
