We have not seen this problem in our testing. What framebuffer are you
using? Do you see this when running any of the Java 3D examples programs
or only in your application? If it is only in your application we would
like you to send us a sample program so we can investigate this problem
further.

Look at the PhysicalBody class. In it are attributes to set the left and right
eye position.

The view frustrum will only be parallel if an orthographic projection
is used. By default a perspective projection is used.
