Stereoscopy creates the impression of three-dimensional depth from a pair of two-dimensional images. [5] Human vision, including the perception of depth, is a complex process, which only begins with the acquisition of visual information taken in through the eyes; much processing ensues within the brain, as it strives to make sense of the raw information.
Old Zeiss pocket stereoscope with original test image A common Underwood & Underwood Stereoscope. A stereoscope is a device for viewing a stereoscopic pair of separate images, depicting left-eye and right-eye views of the same scene, as a single three-dimensional image.
Stereoscopy became popular during Victorian times with the invention of the prism stereoscope by David Brewster. This, combined with photography, meant that tens of thousands of stereograms were produced. Until about the 1960s, research into stereopsis was dedicated to exploring its limits and its relationship to singleness of vision.
The stereo, stereoscopic or dissecting microscope is an optical microscope variant designed for low magnification observation of a sample, typically using light reflected from the surface of an object rather than transmitted through it. The instrument uses two separate optical paths with two objectives and eyepieces to provide slightly ...
It is not flat like two-dimensional art, which consists of paintings, drawings and photographs. Pottery and sculpture are examples of three-dimensional art. Form is the three-dimensional artwork. Forms can be geometric or organic. Three-dimensional art has volume, which is the amount of space occupied by the form.
Examples of autostereoscopic displays technology include lenticular lens, parallax barrier, and integral imaging. Volumetric and holographic displays are also autostereoscopic, as they produce a different image to each eye, [ 2 ] although some do make a distinction between those types of displays that create a vergence-accommodation conflict ...
Popular examples of these devices include the Oculus Quest 2, HTC Vive, Valve Index and the Microsoft HoloLens. VAC can be experienced by bringing a virtual object very close to one's eyes in the headset and trying to focus on it. [17] Not all 3D displays cause the vergence-accommodation conflict.
Stereoscopy is the most widely accepted method for capturing and delivering 3D video. It involves capturing stereo pairs in a two-view setup, with cameras mounted side by side and separated by the same distance as is between a person's pupils.
