Line 1:
−A '''3D display''' is a type of [[display]] that can show different focal depths at the same time. The purpose of a 3D display is to enable a 3D human-computer interaction loop, which can be used in 3D software for design and sharing ideas.+
−A 3D display shows [[depth cue]]s based largely on focus and/or [[stereopsis]]. A [[light field display]] is a type of display that can show full proper focus.
−
−3D displays can be world-fixed, like mounted on a desk, or they can be head fixed, like built into a [[VR headset]].
−
−3D is more than just stereoscopic flat images.
−
−==Approaches==
−There are multiple ways to get a 3D display to show proper focus, thereby giving proper [[accommodation]] cues. The two main ways are [[holographic display]]s and [[light field display]]s. A light field display sends focal stacks of images based on [[ray]]s to the eye.
−
−Multifocal displays are displays that show multiple focus images at the same time, so that the eye can choose what to focus on.
−
−A partial form of 3D displays is to use stereoscopy or autostereoscopy using parallax barriers.
