Mapping class group — In mathematics, in the sub field of geometric topology, the mapping class group is an important algebraic invariant of a topological space. Briefly, the mapping class group is a discrete group of symmetries of the space. Contents 1 Motivation 2… … Wikipedia
Mapping cone — In mathematics, especially homotopy theory, the mapping cone is a construction Cf of topology, analogous to a quotient space. It is also called the homotopy cofiber, and also notated Cf. Contents 1 Definition 1.1 Example of circle … Wikipedia
Sphere packing — In mathematics, sphere packing problems are problems concerning arrangements of non overlapping identical spheres which fill a space. Usually the space involved is three dimensional Euclidean space. However, sphere packing problems can be… … Wikipedia
Cube mapping — The lower left image shows a scene with a viewpoint marked with a black dot. The upper image shows the net of the cube mapping as seen from that viewpoint, and the lower right image shows the cube superimposed on the original scene. In computer… … Wikipedia
Reflection mapping — An example of reflection mapping. In computer graphics, environment mapping, or reflection mapping, is an efficient Image based lighting technique for approximating the appearance of a reflective surface by means of a precomputed texture image.… … Wikipedia
UV mapping — is a 3D modeling process of making a 2D image representing a 3D model. The map transforms the 3D object onto an image known as a texture. In contrast to X , Y and Z , which are the coordinates for the original 3D object in the modeling space, U… … Wikipedia
Riemann mapping theorem — In complex analysis, the Riemann mapping theorem states that if U is a simply connected open subset of the complex number plane Bbb C which is not all of Bbb C, then there exists a biholomorphic (bijective and holomorphic) mapping f, from U, onto … Wikipedia
Bump-mapping — Placage de relief Le placage de relief (en anglais Bump mapping) est un terme informatique qui désigne la technique utilisée, par exemple dans les jeux vidéo, et qui sert à donner du relief aux objets, textures ou à toutes autres choses en 2D ou… … Wikipédia en Français

Bump mapping — is a computer graphics technique where at each pixel, a perturbation to the surface normal of the object being rendered is looked up in a heightmap and applied before the illumination calculation is done (see, for instance, Phong shading). The… … Wikipedia
