  2. Stereoscopy - Wikipedia

    en.wikipedia.org/wiki/Stereoscopy

    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.

  3. Chromostereopsis - Wikipedia

    en.wikipedia.org/wiki/Chromostereopsis

    Blue–red contrast demonstrating depth perception effects 3 Layers of depths "Rivers, Valleys & Mountains". Chromostereopsis is a visual illusion whereby the impression of depth is conveyed in two-dimensional color images, usually of red–blue or red–green colors, but can also be perceived with red–grey or blue–grey images.

  4. Stereopsis - Wikipedia

    en.wikipedia.org/wiki/Stereopsis

    In Victorian times it was the prism stereoscope (allowing stereo photographs to be viewed), while in the 1920s it was red-green glasses (allowing stereo movies to be viewed). In 1939 the concept of the prism stereoscope was reworked into the technologically more complex View-Master , which remains in production today.

  5. Random dot stereogram - Wikipedia

    en.wikipedia.org/wiki/Random_dot_stereogram

    The random dot stereogram provided insight on how stereo vision is processed by the human brain. According to Ralph Siegel, Julesz had "unambiguously demonstrated that stereoscopic depth could be computed in the absence of any identifiable objects, in the absence of any perspective, in the absence of any cues available to either eye alone." [1]

  6. Anaglyph 3D - Wikipedia

    en.wikipedia.org/wiki/Anaglyph_3D

    Red-cyan filters can be employed because our vision processing systems use red and cyan comparisons, as well as blue and yellow, to determine the color and contours of objects. [11] In a red-cyan anaglyph, the eye viewing through the red filter sees red within the anaglyph as "white", and the cyan within the anaglyph as "black".

  7. 3D stereo view - Wikipedia

    en.wikipedia.org/wiki/3D_stereo_view

    In 1833, an English scientist Charles Wheatstone discovered stereopsis, the component of depth perception that arises due to binocular disparity.Binocular disparity comes from the human eyes having a distance between them: A 3D scene viewed through the left eye creates a slightly different image than the same scene viewed with the right eye, with the head kept in the same position.

  8. Depth perception - Wikipedia

    en.wikipedia.org/wiki/Depth_perception

    The perception of perspective is possible when looking with one eye only, but stereoscopic vision enhances the impression of the spatial. Regardless of whether the light rays entering the eye come from a three-dimensional space or from a two-dimensional image, they hit the inside of the eye on the retina as a surface.

  9. Stereoscope - Wikipedia

    en.wikipedia.org/wiki/Stereoscope

    Disadvantages of stereo cards, slides or any other hard copy or print are that the two images are likely to receive differing wear, scratches and other decay. This results in stereo artifacts when the images are viewed. These artifacts compete in the mind resulting in a distraction from the 3D effect, eye strain and headaches.
