I am try to get a stereo display program to work on an Iris. The problem
that I am having is that to stereo plate flips between the left and right
eye at 60Hz, so I need to make sure that I am alternating eyes with each
buffer swap. Unfortunately, swapbuffers() is non-blocking, so that if I
can actually draw faster than 120Hz, I get two updates per buffer swap,
which has the effect of always just showing one eye. Is there a way to
make swapbuffers() to be blocking? Is there a way to know when the screen
refresh happens? What have other people done about this problem? I have
just subscribed to this newsgroup, so I don't know if this problem has been
addressed previously.
Thanks,
