Opengl Stereoscopic View
Message 1 in thread
I am trying to create a stereo view using QGLContext. My code is as
follows:
QGLContext *cx;
QGLFormat f;
f.setStereo( TRUE );
QGLFormat::setDefaultFormat( f );
cx->setFormat( f );
if ( !cx->create() )
printf("FALSE \n");
if ( !cx->format().stereo() )
printf("FALSE \n");
when this is ran create() for the rendering context always returns FALSE as
does
stereo(). This graphics card is capable of supporting stereo view. Any
suggestions would be appreciated.

Take a look at this thread:
http://lists.trolltech.com/qt-interest/2006-12/thread00672-0.html
I had the same issue as you can see which was resolved by trolltech
after I submitted a bug report. This affects also Qt 4.2.2, but they
told me the fix is going to go into the next maintenance release. If you
have an nvidia card you could check with NV Pixel Format
(http://developer.nvidia.com/object/nvpixelformat.html) (if and) which
pfd provides a working stereo and then request it via the qt mechanism,
if that does not work or your card is different then you could file a
bug report unless someone from trolltech can clarify whether you are
affected by the same issue.
