[comp.sys.sgi] Help with stereo

certain@glycine.cs.unc.edu (Andrew Certain) (03/27/91)

We are using the Stereographics CrystalEyes stereo system (the one that
you can order with your Iris) and are having a problem with menus.  The
problem is that the operating system wasn't built for stereo and so when
you call dopup, it draws the menu in one eye only.  Has anybody thought
of a workaround?

    You should be able to put up the menu twice, off-set in the vertical axis
by the separation between the left and right eye image y origins.  Thats how
we do it for 3D text, and how we plan to do it for menus.  I'm anxious to
experiment with varying the Z-axis of the menus too ( pop-out menus???).

This is what we do for everything as well; unfortunately, we draw menus with
a call to dopup(), and we can't call a second one until the first one has
terminated (the user has made his/her selection).  Does anybody have a
workaround?
