Full-depth-cue display
A solidview display is a display gadget that can show solid-looking objects. It does this by using focal cues.
Solidity can be generated using holographic displays and light field displays.
Solidview displays work by showing different focal depths at the same time.
Solidview displays connected to a computer system can enable a 3D human-computer interaction loop, which can be used in 3D software for design.
A solidview display shows depth cues based largely on focus and/or binocular disparity.
Holography is theoretically not necessary for a full solidview display.
A light field display is a type of display that can show full proper focus.
Solidview displays can be world-fixed, like mounted on a desk, or they can be head fixed, like built into a VR headset.
Approaches[edit]
There are multiple ways to get a solidview display to show proper focus, thereby giving proper accommodation cues. A light field display sends focal stacks of images based on rays 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 biscopy or autobiscopy using parallax barriers.
