A block diagram describing the process of driving a StereoMirror ™ monitor
with a computer is shown in the illustration below. The left eye and right eye
images are sent to their respective AMLCDs independently and without any
special treatment (with the exception of accommodating for the fact that
the upper monitor is seen in a mirror; see discussion below). Presenting
the stereo pair of images requires a setup or software application that
accommodates dual-monitor stereo viewing. No additional modification
is needed for use with the StereoMirror
™ monitor design.
Any software application that uses the OpenGL quad-buffered stereo features
is compatible with the StereoMirror
™ . Quad-buffered stereo is a feature of
the OpenGL 3D graphics library that allows an application to define two
separate right/left eye viewpoints instead of the normal single monoscopic
viewpoint. The two viewpoints are defined to give the correct parallax
separation for the
proper stereo effect.
Once the two view-
points have been
defined the 3D scene
is rendered identically
for each of the two
viewpoints. Many
commercial 3D
applications already
have stereo viewing
modes using the
OpenGL stereo
features.
Since the upper
display of the monitor
is seen in reflection, a
mirror-flip operation
must be performed
on that data path. In
the current product
this is accomplished
using an auxiliary signal processing board in the data path to the upper
monitor. Driving a StereoMirror
™ monitor is identical to driving a pair of
projection displays used to show stereoscopic images with crossed polarizers
in the two separate light paths. An off-the-shelf, dual-output graphics card
is employed to drive the two monitors, again with no special preparation.
