Can you explain further? How and where do you adjust the default eye change? We
adjusted the eye separation this way.
body.setLeftEyePosition(new Point3d(-0.005,0,0));
body.setRightEyePosition(new Point3d(0.005,0,0));
Really hope you can enlighten us?

Last time I used Java3D stereo you still had to change the default eye
seperation which
is set to wide for the simple stereo canvas. This is most likely what
you are talking about.
