The software should run with a variety of hardware. We've implemented the 3
basic types of stereoscopic viewing.

1) Anaglyph: which consists of Red/Cyan glasses. This method works on any
screen or surface since it relies on color theory to separate the images for
the left/right eyes, but suffers from some color distortions. We often demo
the viewer using this mode since it's the most widely accepted and works on
brilliant LCD HDTVs and even printed flyers. You can find these glasses in
various places like science or toy stores. You can also pickup a pair via
some 3D DVDs like "Spy Kids 3D." So, check the bargain bin. :) 

2) Passive: This method retains all of the full color information but
requires two projectors with polarized filters in front of them. Common
installations that follow this setup are the Geowall and IMAX theatres. We
often use this for live demos or long term viewing since it's more
comfortable to view. To use this mode on a supporting system you will need
to enable "stereo" via your graphics driver as well as "clone mode stereo."
We have only tested this with NVIDIA software to date, so your mileage may
vary.

3) Shutter Glasses: If your system supports shutter glasses via a 3-pin DIN
on the back of your graphics board, you can use this mode. You will need
supporting shutter glasses which can cost anywhere from $50-$400 dollars.
Just be sure to enable "stereo" in your graphics driver with the source set
to "3 pin DIN".

Hope this helps. :)

This sounds very cool, can you recommend suitable hardware, or at least
describe what sort of hardware is compatible with this?

I have only LCD monitors, so plain shutter glasses won't work,
unfortunately.
