Hi Chems,

The Stereo option shows up in VMD for example but I did have to edit the code for ParaView and change the default stereo option from
red-green to "crystal eyes stereo" to get the frame sequential stereo to work.
What is the default stereo mode for SciRun??? My graphics driver is configured for stereo and it is working - see config file below

HI Jack,

I've been trying to understand this better myself. I've had some success with stereo video in SCIRun using an xorg.conf file that was provided to me by a vendor. Once the settings are configured correctly for your hardware, the stereo check box should be available in Viewer Options.

I think the important parts are the Modeline settings:

Modeline "1400x1050_96_GTF" 205.45 1400 1512 1664 1928 1050 1051 1054 1110 -HSync +Vsync

and the Monitor definition:

Section "Monitor"
        Identifier   "Monitor[0]"
        VendorName   "Monitor Vendor"
        ModelName    "DP8000"
        HorizSync    25.0 - 108.0
        VertRefresh  50.0 - 256.0

here is a link to the complete file:

http://solar.sci.utah.edu/software/SCIRun/stereo/xorg.conf.txt

I wish I could be more help. Hope this helps you get started towards a solution.
