Anamorphosis
Anamorphosis is a distorted projection requiring the viewer to occupy a specific vantage point, use special devices, or both to view a recognizable image. It is used in painting, photography, sculpture and installation, toys, and film special effects. The word is derived from the Greek prefix ''ana-'', meaning "back" or "again", and the word ''morphe'', meaning "shape" or "form". Extreme anamorphosis has been used by artists to disguise caricatures, erotic and scatological scenes, and other furtive images from a casual spectator, while revealing an undistorted image to the knowledgeable viewer. Types of projection There are two main types of anamorphosis: ''perspective'' (oblique) and ''mirror'' (catoptric). More complex anamorphoses can be devised using distorted lenses, mirrors, or other optical transformations. An oblique anamorphism forms an affine transformation of the subject. Early examples of Perspective (graphical), perspectival anamorphosis date to the Renaissance ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Tabula Scalata
Tabula scalata are pictures with two images divided into strips on different sides of a corrugated carrier. Each image can be viewed correctly from a certain angle. Most tabula scalata have the images in vertical lines so the picture seems to change from one image to another while walking past it. The top image on versions with horizontal strips could be seen via a mirror placed above the picture. Some tabula scalata have the two pictures matched in shape and size, which practically creates a simple type of morphing effect when the viewing angle changes. A variation, known as "triscenorama" or "tabula stritta" has three images: two on each side of perpendicular slats in front of the third picture. The basic idea of tabula scalata and tabula stritta is somewhat similar to that of the ancient triangular periaktos theatre coulisse, and that of the modern day Trivision billboard and lenticular printing. Terminology The Latin term "Tabula scalata" was introduced in 1646 by Athanasi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Affine Transformation
In Euclidean geometry, an affine transformation or affinity (from the Latin, ''affinis'', "connected with") is a geometric transformation that preserves lines and parallelism, but not necessarily Euclidean distances and angles. More generally, an affine transformation is an automorphism of an affine space (Euclidean spaces are specific affine spaces), that is, a function which maps an affine space onto itself while preserving both the dimension of any affine subspaces (meaning that it sends points to points, lines to lines, planes to planes, and so on) and the ratios of the lengths of parallel line segments. Consequently, sets of parallel affine subspaces remain parallel after an affine transformation. An affine transformation does not necessarily preserve angles between lines or distances between points, though it does preserve ratios of distances between points lying on a straight line. If is the point set of an affine space, then every affine transformation on can be repre ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Perspective (graphical)
Linear or point-projection perspective (from la, perspicere 'to see through') is one of two types of 3D projection, graphical projection perspective in the graphic arts; the other is parallel projection. Linear perspective is an approximate representation, generally on a flat surface, of an image as it is seen by the eye. Perspective drawing is useful for representing a three-dimensional scene in a two-dimensional medium, like paper. The most characteristic features of linear perspective are that objects appear smaller as their distance from the observer increases, and that they are subject to ''foreshortening'', meaning that an object's dimensions along the line of sight appear shorter than its dimensions across the line of sight. All objects will recede to points in the distance, usually along the horizon line, but also above and below the horizon line depending on the view used.

Mirror
A mirror or looking glass is an object that Reflection (physics), reflects an image. Light that bounces off a mirror will show an image of whatever is in front of it, when focused through the lens of the eye or a camera. Mirrors reverse the direction of the image in an equal yet opposite angle from which the light shines upon it. This allows the viewer to see themselves or objects behind them, or even objects that are at an angle from them but out of their field of view, such as around a corner. Natural mirrors have existed since prehistoric times, such as the surface of water, but people have been manufacturing mirrors out of a variety of materials for thousands of years, like stone, metals, and glass. In modern mirrors, metals like silver or aluminium are often used due to their high reflectivity, applied as a thin coating on glass because of its naturally smooth and very Hardness (materials science), hard surface. A mirror is a Wave (physics), wave reflector. Light consis ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
The Ambassadors (Holbein)
''The Ambassadors'' is a 1533 painting by Hans Holbein the Younger. Also known as '' Jean de Dinteville and Georges de Selve'', after the two people it portrays, it was created in the Tudor period, in the same year Elizabeth I was born. Franny Moyle speculates that Elizabeth's mother, Anne Boleyn, then Queen of England, might have commissioned the painting as a gift for Jean de Dinteville, the ambassador portrayed on the left in the painting. As well as being a double portrait, the painting contains a still life of several meticulously rendered objects, the meaning of which is the cause of much debate. It also incorporates one of the best-known examples of anamorphosis in painting. ''The Ambassadors'' has been part of London's National Gallery collection since its purchase in 1890. Description Although a German-born artist who spent much of his time in England, Holbein here displays the influence of Early Netherlandish painting. He used oils which for panel paintings had been dev ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Caricature
A caricature is a rendered image showing the features of its subject in a simplified or exaggerated way through sketching, pencil strokes, or other artistic drawings (compare to: cartoon). Caricatures can be either insulting or complimentary, and can serve a political purpose, be drawn solely for entertainment, or for a combination of both. Caricatures of politicians are commonly used in editorial cartoons, while caricatures of movie stars are often found in entertainment magazines. In literature, a ''caricature'' is a distorted representation of a person in a way that exaggeration, exaggerates some characteristics and oversimplifies others. Etymology The term is derived for the Italian ''caricare''—to charge or load. An early definition occurs in the English doctor Thomas Browne's ''Christian Morals'', published posthumously in 1716. with the footnote: Thus, the word "caricature" essentially means a "loaded portrait". Until the mid 19th century, it was commonly and m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hans Holbein The Younger
Hans Holbein the Younger ( , ; german: Hans Holbein der Jüngere; – between 7 October and 29 November 1543) was a Germans, German-Swiss people, Swiss painter and printmaker who worked in a Northern Renaissance style, and is considered one of the greatest portraitists of the 16th century. He also produced religious art, satire, and Protestant Reformation, Reformation propaganda, and he made a significant contribution to the history of book design. He is called "the Younger" to distinguish him from his father Hans Holbein the Elder, an accomplished painter of the International Gothic, Late Gothic school. Holbein was born in Augsburg but worked mainly in Basel as a young artist. At first, he painted murals and religious works, and designed stained glass windows and illustrations for books from the printer Johann Froben. He also painted an occasional portrait, making his international mark with portraits of humanist Desiderius Erasmus of Rotterdam. When the Reformation reach ...

Giacomo Barozzi Da Vignola
Giacomo Barozzi da Vignola ( , , ; 1 October 15077 July 1573), often simply called Vignola, was one of the great Italian architects of 16th century Mannerism. His two great masterpieces are the Villa Farnese at Caprarola and the Jesuits' Church of the Gesù in Rome. The three architects who spread the Italian Renaissance style throughout Western Europe are Vignola, Sebastiano Serlio, Serlio and Andrea Palladio, Palladio. He is often considered the most important architect in Rome in the Mannerism, Mannerist era. Biography Giacomo Barozzi was born at Vignola, near Modena (Emilia-Romagna). He began his career as architect in Bologna, supporting himself by painting and making perspective Patterns, templates for inlay craftsmen. He made a first trip to Rome in 1536 to make measured drawings of Roman temples, with a thought to publish an illustrated Vitruvius. Then Francis I of France, François I called him to Fontainebleau, where he spent the years 1541–1543. Here he pro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tommaso Laureti
Tommaso Laureti, often called Tommaso Laureti Siciliano (c. 1530 — 22 September 1602), was an Italian painter from Sicily who trained in the atelier of the aged Sebastiano del Piombo and worked in Bologna. From 1582, he worked for papal patrons in Rome in a Michelangelo-inspired style with special skill in illusionistic perspective, that in his Roman work avoided all but traces of Mannerism. Biography Laureti was born in Palermo, Sicily. After his first master's death in 1547, he settled in Bologna, introducing illusionistic perspective paintings on ceilings to the city, notably an ''Alexander the Great'' ceiling with a painted architectural setting in Palazzo Vizzani. He painted a ''Transportation of the Body of Saint Augustine'' for the church of San Giacomo Maggiore in Bologna. The Mannerist structural elements of the marble and bronze ''Fountain of Neptune'' in Bologna, which is surmounted by Giambologna's ''Neptune'', completed in 1566, were based on a 1563 drawing by Lauret ...

Vanitas
A ''vanitas'' (Latin for 'vanity') is a symbolic work of art showing the transience of life, the futility of pleasure, and the certainty of death, often contrasting symbols of wealth and symbols of ephemerality and death. Best-known are ''vanitas'' still lifes, a common genre in the Low Countries of the 16th and 17th centuries; they have also been created at other times and in other media and genres. Etymology The Latin noun ''vanitas'' (from the Latin adjective ''vanus'' 'empty') means "emptiness", "futility", or "worthlessness", the traditional Christian view being that earthly goods and pursuits are transient and worthless. It alludes to Ecclesiastes , where ''vanitas'' translates the Hebrew word ''hevel'', which also includes the concept of transitoriness. Themes Vanitas themes were common in medieval funerary art, with most surviving examples in sculpture. By the 15th century, these could be extremely morbid and explicit, reflecting an increased obsession with de ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
