Larry,
With luck the price of "real" stereo enabling hardware will start to fall in
the very near future. I don't imagine that it will be too long before the
guys at Nintendo and Playstation convince their bosses so support stereo,
and that demand will push the price down dramatically. With luck the Java 3D
community will be in place by then to provide drivers for the hardware. I'm
sure we can look forward to yet another ideological split though, the MS
"Direct" APIs going one way, while Sun attempts to go another.
I don't think there is anything built in for this but you can override the
Canvas3D postRender method to capture the contents of the Canvas3D and write
it to a file. I believe guys at the NCSA have written some code to also
allow you to capture animated sequences from a Canvas3D. It was posted as:

Hi Daniel,
Thanks for your reply.
I'm sure that the simpler forms of stereo3D would be easy to implement in
JAVA3D. The only really stereo thing to be concerened with would be the
second viewpoint, but apparently there are routines in place that help with
that process, judging by previous posts to the group and at least one other
person that I know of writing stereo JAVA applets. Once you have the second
view, analgyphic images are just operations with color channels, and side by
side doesn't require anything other than planning where to place the views.
Supporting VR gear or LCShutter glasses would be nice, but it's a bit more
involved and I personally wouldn't be expecting that from a JAVA applet for
now.
I have noticed however that when a JAVA applet displays an image, I haven't
been able to figure out how to store the image on my hard disk to view again
later. I'm not sure if that's how the author intended things to be, or
whether it's just how JAVA handles images. In any case, if one can't store
the image directly from the applet, it might be nice to include a link on
your page that would allow that to happen separately from the applet.
Sincerely,
Larry Berlin
