3D with / without goggles

It's possible to create still and moving images with the illusion of depth (3D) in a variety of ways for a viewer wearing glasses or goggles. This can include 360 degree environments. 

For an overview on approaches WITH glasses, see

Without using goggles is called Autostereoscopy -  this is any method of displaying stereoscopic images (adding binocular perception of 3D depth) without the use of special headgear or glasses on the part of the viewer. The method is often expensive, with technology owned or patented by large companies. It has been used by politicians who want to 'physically' appear in more than one place at once (eg Modi in India via 'Musion') as well as for 'live' concerts by dead artists (eg Tupac Shakur at Coachella 2012).

There are two broad approaches currently used to accommodate motion parallax and wider viewing angles: one is eye-tracking, the other involves multiple views such that the display does not need to sense where the viewers' eyes are located. For a good overview, see
