Flatfocus solidview
Flatfocus solidview is when something is twoview solidview and each eye sees a flat focus image.
Every flatfocus solidview entity is twoview flatfocus solidview, because there are minimal solidity cues that enable stereopsis from flat focus images other than binocular cues.
Flatfocus solidview is enabled by stereopsis from binocular disparity, which is a form of partial stereopsis.
It is enabled by twoview technology, which is when something has two independent optical pathways. In flatfocus solidview, each pathway with a flat-focus image, where the whole thing viewed has an appearance of solidity.
When viewed by someone with two eyes, the images fuse together through stereopsis from binocular disparity and form the appearance of a solid object.
Examples are VR games, 3D movies, and View-Master pictures, which are twoview flatfocus solidview images.
