Hi,
I've looked at the demos for stereo display using the Anaglyph (6-9)
mode. I've also played with the OpenGL teapot demo. I tried to set up
two OpenGL cameras and send the render outputs to the two sub-buffers
of the stereo modes (ie, using SelectStereoDrawBuffer), based on the
teapot demo. It seems (at least from what I've tried so far) that
SelectStereoDrawBuffer doesn't have any effect once BeginOpenGL has
been called. Now I've taken a look at
http://www.kyb.mpg.de/bu/people/qvuong/CGV05.html and I think I could
render the same scene with two cameras into two off screen buffers and
blend the two manually in the 0 OpenWindow mode, bypassing the
built-in Anaglyph display method completely. The problem with that is
that I'm only using the Anaglyph display for test purposes, and the
real experiment is going to take place with polarizing glasses. So the
best for me would be to use the 9 display mode for test purposes and
simply change the value to 2 in the real experimental setup, but I'd
also like to use the 3d OpenGL rendering facilities.
So, has anyone had any experience using both OpenGL 3d rendering and
the various stereo display modes of OpenWindow? Is it even possible?
If so, does anyone have some demo code I could look at to get started?
Thanks,
Patrick Mineault
