Although I agree with Mark Hood...I would also like to add that I had
issues with different desktop colors. I completely reinstalled Win2000
and Java 1.2 and Java3D 1.3 and I had some wierd z-clipping issues. It was
not until I changed the colors from 16 bit to 32 bit did things fix
themselves.
So, that's a hint...if you have z-clipping issues, check what your
resolutions
are and also maybe check the colors menu right next to the resolutions
menu in windows.

Subject: [JAVA3D] has Z-clipping anything to do with desktop
resolution????
Hi Community!
Strange things going on.....
Our app uses a 800x600 canvas and configures Z-clipping to
mView.setFrontClipDistance( 1 );
mView.setBackClipDistance( 4500 );
Now I placed a Text2D in front of my camera. I didn't know why, but I had to
give a Z-value < -5.538 (we are looking to -Z) in order to make it display.
Putting it nearer to the camera, it gets clipped away. I didn't understand
that, bc. I set the FrontClipDistance to 1, but ok.
The miracle: I used to do this with a desktop resolution of 1280x1024. If I
now reduce desktop resolution to lets say 1024x768, the Text2D vanished!! If
I push it farther away, it appears again???
Here is a table of desktop resolutions and approx. minimal Z-distances:
1280x1024 -5.6
1152x864 -6.2
1024x768 -7.0
What the hell does the desktop resolution have to do with Z-clipping???? My
Canvas3D always is 800x600, View settings always the same, no changes in
aspect ratio. Desktop bitdepth (I tried 32 and 16) doesn't matter neither.
Environment: XP, JDK1.4.1, Java3D 1.3/DirectX
Anybody has a clue?
Thanks,
- J
