At Weizmann, we've been using a high-performance DLP projector
together with a
Power Mac G5 Quad, with NVIDIA Quadro FX 4500 graphics card
for stereo molecular graphics on a large screen.

BTW, has anyone tried using stereo with a DLP (not LCD) video
projector?
(Don't know what the refresh rate restrictions are on these. The
physical hardware should be capable, but there's no guarantee the
the electronics will support it. Probably requires a darkened room
too).

There we have it then! Port everything to DirectX and use
Vista ! ;) *shudder*
Not to slam M$, but I run vista x64 at home and the hardware
support is awful (manufacturers have yet to distinguish between
driver support for 32 bit or 64 bit i.e. Vista capable on the box
may mean only 32 bit support).
Thanks for looking into it!

Stereo 3D Users:
I tested out the Samsung Syncmaster 2233RZ / NVIDIA 3D Vision bundle
today ($599 for a 120 Hz LCD display with one pair of glasses).
Unfortunately, the 2233RZ display is clearly not yet a drop-in
replacement for your stereo-3D-capable CRT: The display is very
nice,
and the stereo quality is excellent (as good as a CRT!), but only
provided that you:
1. Run Microsoft Vista.
2. Install a high-end GeForce 3D card (9800 GT or similar).
3. Have DirectX-based software than has been modified to support
nVidia's "consumer-grade" stereo API.
4. Use nVidia's 3D Vision glasses and sync emitter (a USB-based
device).
In other words, despite the high stereo image quality, this is not
yet a
servicable stereo 3D solution for professional use. Rats!
I was very much hoping that this new display would nevertheless also
work with existing nVidia Quadro-based Mac or Linux systems with
existing emitters and glasses running existing OpenGL software.
Sadly,
this does not seem to be the case due at least in part to the fact
that
the phase of the sync signal coming out of the Quadro card does not
match the update phase of the LCD display. In addition, light
from the
display itself seems to corrupt the sync signal for StereoGraphics
glasses.
So, in summary, it seems we are out of luck until nVidia does a
bit more
work. Reportedly, there is a driver update coming that will
target use
of nVidia's 3D vision glasses with Quadro-based graphics cards, so
stay
tuned.
Cheers,
Warren
