Implicit surfaceIn mathematics, an implicit surface is a surface in Euclidean space defined by an equation An implicit surface is the set of zeros of a function of three variables. Implicit means that the equation is not solved for x or y or z. The graph of a function is usually described by an equation and is called an explicit representation. The third essential description of a surface is the parametric one: where the x-, y- and z-coordinates of surface points are represented by three functions depending on common parameters .
Graphics softwareIn computer graphics, graphics software refers to a program or collection of programs that enable a person to or models visually on a computer. Computer graphics can be classified into two distinct categories: raster graphics and vector graphics, with further 2D and 3D variants. Many graphics programs focus exclusively on either vector or raster graphics, but there are a few that operate on both. It is simple to convert from vector graphics to raster graphics, but going the other way is harder.
Literary realismLiterary realism is a literary genre, part of the broader realism in arts, that attempts to represent subject-matter truthfully, avoiding speculative fiction and supernatural elements. It originated with the realist art movement that began with mid-nineteenth-century French literature (Stendhal) and Russian literature (Alexander Pushkin). Literary realism attempts to represent familiar things as they are. Realist authors chose to depict everyday and banal activities and experiences.
Geometric modelingNOTOC Geometric modeling is a branch of applied mathematics and computational geometry that studies methods and algorithms for the mathematical description of shapes. The shapes studied in geometric modeling are mostly two- or three-dimensional (solid figures), although many of its tools and principles can be applied to sets of any finite dimension. Today most geometric modeling is done with computers and for computer-based applications. Two-dimensional models are important in computer typography and technical drawing.
Social realismSocial realism is the term used for work produced by painters, printmakers, photographers, writers and filmmakers that aims to draw attention to the real socio-political conditions of the working class as a means to critique the power structures behind these conditions. While the movement's characteristics vary from nation to nation, it almost always uses a form of descriptive or critical realism. The term is sometimes more narrowly used for an art movement that flourished between the two World Wars as a reaction to the hardships and problems suffered by common people after the Great Crash.
Socialist realismSocialist realism is a style of idealized realistic art that was developed in the Soviet Union and was the official style in that country between 1932 and 1988, as well as in other socialist countries after World War II. Socialist realism is characterized by the depiction of communist values, such as the emancipation of the proletariat. Despite its name, the figures in the style are very often highly idealized, especially in sculpture, where it often leans heavily on the conventions of classical sculpture.
