Here's my encounter with setting stereo in Java3D. Hope you could enlighten me.
My stereo projection in java3d seems a little odd, rather than
laterally displacing the projections to produce binocular disparity,
the projections for the left and right eyes are rotated to produced
the disparty. The causes the disparity to decrease as the 3D object
moves further (a behavior we expected) and then after a distance the
disparity increases again. The left right projections seems to cris
cross.
As both left and right projection are rotated, rather than
translated, the disparity is actually zero a center point around 5
meters in front of the camera. The causes an unnatural effect when the
user move his/her head. By motion parallax, the nearer objects should
move in the opposite direction to the head movement. In this case, due
to the rotated projections, nearer objects move in the same direction
as the head while the further objects actually moves more than the
objects near the 'center point' where the disparity is least. This
conflicts with the usual visual cues we are used to and causes
discomfort.
We r using Nvidia quadrofx workstation cards and have tried to
correct these rotated disparity by specifying additional left right
eye projection matrices. However, when we turn on compatibility mode to
set in the matrices, canvas3D does not render the scene.
What could be the problem and is there any other ways to get
around the problem of "rotated disparity"?
Your assistances is greatly appreciated.

I'm really not sure what your question is. If you use a stereo-capable
hardware and have all the required drivers installed and have a
Java3D-application which has the stereoscopic view enabled your hardware
will display it.
