style='font-size:10.0pt;font-family:"Lucida Sans";color:blue'>You are thinking
of showing stereo images by putting a separate image on each screen yourself,
but there is a more automatic way to do it. The Wildcat II 5110 drivers have a
setting to enable stereo, at least on Windows and maybe on Linux. You need to
go into the driver control and look deep in the Advanced section. When you
enable stereo in the driver, you also have to tell VTK to ask OpenGL to display
in stereo, and I think you have done the right settings in VTK for that to
work. Both video outputs from the display adapter will show the same image most
of the time, so you can no longer extend your desktop to on the second display
this way.<o:p></o:p></span></font></p>

a call to StereoUpdate, and I’m not sure what “StereoUpdate”
does. It may not be necessary. I haven’t done this in a year or two, and
you used to be able to use the regular Render() command once you enabled stereo
in the render window.<o:p></o:p></span></font></p>
