I already did but couldn't find an appropriate method.

I am not using SimpleUniverse and set up everything explicitly.

Yes, both eyes share the same focus point and your eyes are crossed, this is
called convergence. This determines which part of the scene will appear in
front of the screen (part of the scene which lies in front of the focus point)
and which part will appear behind the scene (this is what I want to control).
Another possibility is to use parallel cameras and shift the images to
"simulate" a focus point (or point with zero parallax). The amount of the shift
determines where the focus point is.

So what I want to know is how to manipulate where the point with zero parallax
occurs.
But there is no documentation about stereoscopy available.

To go into more detail: I use a stereo system from Sterographics which requires
the images of the right and left eye to be put on top of each other. Then there
is a little adapter which doubles the monitor frequency and shutter glases
synchronized wih this adapter. Since the graphics card is working with the
normal frequency the upper screen buffer is stretched to be fill the whole
screen. Since the screen works with double frequency the next picture displayed
is the lower part of the screen buffer, also stretched.
In this way you can produce stereoscopic images without a special card. I' ve
included a demo program for those who have also this equipment (source is
included in jar file). But this application uses compatibility mode and 2
cameras. But I would like to use the intrinsic stereo support.

I would like to hear a comment from the sun guys on that. Thanks.
