The collinearity equations are a set of two equations, used in photogrammetry and computer stereo vision, to relate coordinates in a sensor plane (in two dimensions) to object coordinates (in three dimensions).
Op art, short for optical art, is a style of visual art that uses optical illusions. [1] Op artworks are abstract, with many better-known pieces created in black and white. Typically, they give the viewer the impression of movement, hidden images, flashing and vibrating patterns, or swelling or warping.
Optical illusion is also used in film by the technique of forced perspective. 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.
According to the Hockney–Falco thesis, such optical aids were central to much of the great art from the Renaissance period to the dawn of modern art. The Hockney–Falco thesis is a controversial theory of art history , proposed by artist David Hockney in 1999 and further advanced with physicist Charles M. Falco since 2000 (together as well ...
In geometry, collinearity of a set of points is the property of their lying on a single line. [1] A set of points with this property is said to be collinear (sometimes spelled as colinear [2]). In greater generality, the term has been used for aligned objects, that is, things being "in a line" or "in a row".
A theory of art is intended to contrast with a definition of art. Traditionally, definitions are composed of necessary and sufficient conditions, and a single counterexample overthrows such a definition. Theorizing about art, on the other hand, is analogous to a theory of a natural phenomenon like gravity.
Lines are optical phenomena that allow the artist to direct the eye of the viewer. The optical illusion of lines does exist in nature, and in visual arts, elements can be arranged to create this illusion. The viewer unconsciously "reads" the image through the continuous arrangement of different elements and subjects at varying distances.
Geometrical optics does not account for certain optical effects such as diffraction and interference, which are considered in physical optics. This simplification is useful in practice; it is an excellent approximation when the wavelength is small compared to the size of structures with which the light interacts.
