Shutterglasses enable full screen
high resolution viewing, and provide a high quality method for viewing
3D images on a computer.
LCD
shutter glasses alternately block out light coming to the left and right
eyes.
This is done at high frequency in order to eliminate flicker.
The shutters are synchronized (by a wire or an IR signal) with
the sequential presentation of the left and right images to the monitor
by your graphics board.
Various methods of sending the images to the monitor may be
employed.
An interlace scheme is sometimes required (e.g. for the
inexpensive (VRSurfer
glasses).
However, modern high performance graphics cards often do not
support this old display mode, which has the disadvantage that the
individual picture resolution is effectively halved in the vertical.
Currently, the most effective computer display of 3D images using
shutterglasses involves high
resolution “page flipping”. In this method, full-screen left and
full-screen right images are alternatively transferred to the monitor by
the video card itself. High refresh rates (> 100 Hz) are recommended.
Most shutter glasses come with software to perform the
decomposition of a left-right stereo-jpeg (.jps) pair into the two pages that
are subsequently flipped by your graphics adapter. Software plugins for
web-browsers enable you to directly view the .jps images sent by out by
a server. However, only certain graphics cards support such 3D display, but the
number is already impressive, prices are reasonable, and the results are
quite good. One inexpensive package consists of i-art “4 in 1”
shutter glasses and driver software for a wide range of PC graphics
cards (see http://www.demensional.com).

WARNING: Although the field is evolving, there is no standard for
triggering the shutterglasses. Each vendor has its own scheme.
Finding software
with stable problem-free drivers is THE PROBLEM. Get the
most recent updates from the vendor's website and have patience!
