We tested stereo support using an AccelGalaxy card. Java 3D supports stereo
by using the stereo API in OpenGL. We found that some cards required
a separate extension to be called to enable stereo and so these cards
are not working. Once the manufacturers update their drivers to support
stereo as described in the OpenGL specification then stereo should work
in Java 3D.
We have also determined that some cards do not keep a separate Z-buffer
per eye. This leads to an incorrect image for one eye. This problem came as
a surprise to us but we plan on coming up with a "fix" for this in an
upcoming release.
