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 cue]]s based largely on focus and/or [[binocular disparity]].+
A '''3D display''' is a display gadget that can show solid-looking objects. It does this by using focal cues. Solidity can be generated using [[holographic display]]s and [[light field display]]s. 3D displays work by showing different focal depths at the same time. The term can also refer to a [[multiple viewpoint display]].

−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]].

−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 [[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.
