Martin,

I'm also interested in setting up stereo for a medical application. I am currently trying to get funding for a polarized projector setup along the lines of the geowall project (http://geowall.geo.lsa.umich.edu/intro.html).

Since you mentioned that "our stereo is set up for shutter glasses", I just wanted to make sure that SCIRun would be able to be set up for the polarized application.

Thanks in advance.

Ok so this really requires more information. Our stereo is set up for
shutter glasses. This means you need to have a display device that can
refresh quickly enough. (~120Hz) It sounds like you have this... This
gives us left and right eye at 60Hz each... I know we have made this
work at a lower refresh rate for a larger display. If I remember
correctly Option "Stereo" "3" is correct for shutter glasses.

When I first got this working on linux, I had to have a Quadro card to
get stereo enabled in the driver, I'm not sure if this is still true.

We attempt to get a context that supports stereo when you start up, if
you can get such a context the stereo button will not be greyed out.

I haven't done this myself for a number of years, but if you need
additional help I am happy to do so.
