8.8 3D projection
3D setup
The projector is capable of displaying 3D images and movies in active stereoscopic 3D.
Setup of a 3D installation requires an advanced understanding of 3D systems, both for the projector as well as
for the system the signal source originates from. In a 3D setup it is crucial that the projected images are
perfectly synchronized through the whole signal path, from the signal source to the picture viewed through the
3D goggles.
Regarding setting up the proper signal source, please refer to the user manual or online help for that graphic
card. For example: when using NVIDIA Quadro cards, use the NVIDIA Control Panel to manage your 3D
settings.
8.8.1 Active Stereo & Passive Stereo
What is Passive Stereo?
Passive Stereoscopic 3D (also known as "Passive Stereo") is the standard method of creating the illusion of
depth in an image, by means of stereopsis for binocular vision.
To present stereoscopic pictures, two images are projected superimposed onto the same screen through
polarizing filters or presented on a display with polarized filters. For Digital Cinema, a silver screen is used so
that polarization is preserved. On most passive displays every other row of pixels are polarized for one eye or
the other. This method is also known as interlacing.
The viewer wears glasses which contain a pair of opposite polarizing filters. As each filter only passes light
which is similarly polarized and blocks the opposite polarized light, each eye only sees one of the images, and
the effect is achieved.
