Hi,
I have installed eclipse, java sdk 1.4.2 and j3d 1.3.1.
I started the sun j3d tutorial however when i run the first program i get a
blank white canvas with nothing shown.
My code is identical to the one in the first chapter.
Upon closing the window in the eclipse console i get this error come up
twice:
wglCreateContext Failed: The pixel format is invalid.

Any ideas how to get it working or what could be wrong ?
Im on a win2k PC with a radeon 9600XT 256meg GC with the latest ATI drivers.
Thank you,

Alex

There are two versions of Java3D, a DirectX and an OpenGL version. I use
the OpenGl but when I tried it on one particular Win2K installation I got
a blank canvas. I never figured out why but I solved it by using the
DirectX version instead (which is not as good). Could be the problem, in
which cas I suspect that it's something to do with the graphics card.

It has to do with ATI driversets that have a flaw in them and that causes
the program to not run properly. If you run the program using the DirectX
runtime, then you will see that the program runs just fine. Only the
OpenGL aspect is messed up and yet that is the one I want to work with.
The folks at javadesktop.org have filed the bug @ ATI's website. I also
read that if the driver is somehow run in 16 bit then the problem is
alleviated. Allegedly the 1.3.2 build also implements a workaround the
problem.

Regards.
