  2. Anamorphosis - Wikipedia

    en.wikipedia.org/wiki/Anamorphosis

    Anamorphic street art by Manfred Stader. While not as widespread in contemporary art, anamorphosis as a technique has been used by contemporary artists in painting, photography, printmaking, sculpture, film and video, digital art and games, holography, [1] street art and installation. The latter two art forms are largely practised in public ...

  3. Distortion - Wikipedia

    en.wikipedia.org/wiki/Distortion

    Distortion occurs when the transfer function F is more complicated than this. If F is a linear function, for instance a filter whose gain and/or delay varies with frequency, the signal suffers linear distortion. Linear distortion does not introduce new frequency components to a signal but does alter the balance of existing ones.

  4. Perspective distortion - Wikipedia

    en.wikipedia.org/wiki/Perspective_distortion

    Perspective distortion refers to the manipulation of visual perception through deliberate techniques that create altered or exaggerated views of objects or scenes. This concept has not only shaped art and architecture but has also played a critical role in challenging and expanding the limits of human perception.

  5. Phantogram (optical illusion) - Wikipedia

    en.wikipedia.org/wiki/Phantogram_(optical_illusion)

    The anamorphic distortion of the source image crucial to the illusion can be understood by likening the images to projections of a 3D object onto a plane (e.g. a sheet of paper) originating from the location of the viewer's eyes. The base of the object meets the plane where the object stands, while the tip of the object is "projected" to a more ...

  6. Distortion (optics) - Wikipedia

    en.wikipedia.org/wiki/Distortion_(optics)

    In geometric optics, distortion is a deviation from rectilinear projection; a projection in which straight lines in a scene remain straight in an image.It is a form of optical aberration that may be distinguished from other aberrations such as spherical aberration, coma, chromatic aberration, field curvature, and astigmatism in a sense that these impact the image sharpness without changing an ...

  7. Optical illusion - Wikipedia

    en.wikipedia.org/wiki/Optical_illusion

    Op art is a style of art that uses optical illusions to create an impression of movement, or hidden images and patterns. Trompe-l'œil uses realistic imagery to create the optical illusion that depicted objects exist in three dimensions.

  8. Curvilinear perspective - Wikipedia

    en.wikipedia.org/wiki/Curvilinear_perspective

    Curvilinear barrel distortion Curvilinear pincushion distortion. Curvilinear perspective, also five-point perspective, is a graphical projection used to draw 3D objects on 2D surfaces, for which (straight) lines on the 3D object are projected to curves on the 2D surface that are typically not straight (hence the qualifier "curvilinear" [citation needed]).

  9. Fisheye lens - Wikipedia

    en.wikipedia.org/wiki/Fisheye_lens

    A fisheye lens is an ultra wide-angle lens that produces strong visual distortion intended to create a wide panoramic or hemispherical image. [4] [5]: 145 Fisheye lenses achieve extremely wide angles of view, well beyond any rectilinear lens.
