How Stereoscopic 3D Works
Stereoscopy is a digital technique for allowing our brain to see stereopsis (3D
images) by tricking it. This technique is done is by presenting each eye with a
different image. The left eye is presented a picture that shows the left perspec-
tive. Similarly, the right eye is presented with an image of the right perspec-
tive. In this way, each eye is presented with a different image independently
and our brain puts them together resulting in the perception of depth. In 3D
projection this is accomplished by rapidly alternating between the left and right
images while at the same time 3D glasses "blink" to allow the corresponding
eye to see the correct image at the correct time. The equipment required to
make stereoscopic 3D possible is a high frequency projector like the AAXA
LED Showtime 3D, a 3D Graphics card like the Nvidia Geforce series, and ac-
tive shutter glasses such as the NVIDIA 3D Vision Kit glasses.
