Autostereoscopic
displays get their name from the fact that glasses are not
required in order to view the stereoscopic 3D images. They range in
size from 15" LCDs to 50" plasma screens.
Most personal
viewing autostereoscopic screens require the viewer to place
their head in a specific place (known as the sweet-spot) so that they
can see the 3-D effect properly. They are designed for one person to
view the screen at a time (although it is sometimes possible to have
up to three viewers). These screens are well suited to applications
such as:
| • |
3D
design & modeling |
| • |
3D data visualisation |
| • |
Interactive visualisation
|
| • |
3D photo/video
viewing |
Using the correct graphics card and settings,
nearly all stereo-enabled software is capable of running on these screens
without modification.
The IRIS-3D
screen, released in 2004, is a high-end autostereo screen offering 1600x1200
resolution. It works using an internal projection system and a concave
mirror and eliminates the cross-talk (ghosting) associated with some
other stereoscopic viewing devices.
The RD3D and DTI screens use a parallax
barrier device that creates the illusion of 3D by showing your left
eye the even pixel columns and your right eye the odd ones. They can
both also work as normal 2D displays - see below for an explanation.
How the parallax barrier works in 3-D and 2-D
modes
SeeReal offer a range of LCD screens
up to 20" and a high-resolution image (1600 x 1200). Their range
includes eye-tracked models which allow the viewer to move their head
without losing the 3D image. SeeReal's screens cannot be switched into
standard 2D mode.
