Hi All,
I recover al old thread...
I'm trying to use the stereo setup with the same settings you mentioned,
both with the Vuzix HMD, and with the eMagin Z-800 (http://www.3dvisor.com)
I have a Quadro FX 3700 as graphics HW.
Unfortunately, I can only see the image "flickering" because of the
switch between the right and left images, but no way to address the 2
different frames to the HMD right/left channels.
Which settings might be wrong?
On the nVidia Panel I tried all of the combination among:
** Force stereo shuttering
** Stereo - Enable
** Stereo - Swap Eyes
settings, always using the --stereo QUAD_BUFFER option on osgViewer.
Is there any dependency with the multiple display setup?
I tried the clone and Dual View options, but still no luck...
Thank you on advance for any suggestion!
Cheers_ricky

Thanks for the help. That all worked, more or less out-of-the-box,
using QUAD_BUFFER. As suggested, we had to enable stereo in the OpenGL
driver.
I was slightly misinformed about the actual hardware, what we are
actually using is this :
http://www.vuzix.com/iwear/products_vr920.html, which also uses a
field sequential sort of stereo. LIke I said though, all works OK.
Out of curiosity, in a couple of our apps we set various features of
the views e.g. window sizes (via graphics context traits), projection
matrix resize policy and so on. For anaglyphic stereo mode, this was
all fine, but in quad buffer, we got lots of OpenGL warnings. Turning
a big set of methods off fixed them in the short term, but lost some
functionality; in the long term we'd like to fix this.Are there things
that one shouldn't do in quad_buffer that are OK in other stereo modes?
