Scalable Vector Graphicsdroite|400px|vignette|Différence conceptuelle entre les et vectorielles.Les images vectorielles peuvent être agrandies à l’infini. Le Scalable Vector Graphics (en français « graphique vectoriel adaptable »), ou SVG, est un format de données ASCII conçu pour décrire des ensembles de et basé sur XML. Ce format inspiré directement du VML et du PGML est spécifié par le World Wide Web Consortium.
Music visualizationMusic visualization or music visualisation, a feature found in electronic music visualizers and media player software, generates animated based on a piece of music. The imagery is usually generated and rendered in real time and in a way synchronized with the music as it is played. Visualization techniques range from simple ones (e.g., a simulation of an oscilloscope display) to elaborate ones, which often include a number of composited effects. The changes in the music's loudness and frequency spectrum are among the properties used as input to the visualization.
Visite virtuellevignette|Johannesburg-Motor-Show-Virtual-Tour La visite virtuelle permet de simuler la visite d'un site, souvent à 360 degrés. L'image représentant le site visité évolue dynamiquement, en interaction avec la demande de l'utilisateur. Cette technique permet la visite de musées, de sites touristiques, de bâtiments, parfois de villes entières, ainsi que de biens immobiliers en vente ou en location sur internet.
Shadow mappingShadow mapping or shadowing projection is a process by which shadows are added to 3D computer graphics. This concept was introduced by Lance Williams in 1978, in a paper entitled "Casting curved shadows on curved surfaces." Since then, it has been used both in pre-rendered and realtime scenes in many console and PC games. Shadows are created by testing whether a pixel is visible from the light source, by comparing the pixel to a z-buffer or depth image of the light source's view, stored in the form of a texture.
Data conversionData conversion is the conversion of computer data from one to another. Throughout a computer environment, data is encoded in a variety of ways. For example, computer hardware is built on the basis of certain standards, which requires that data contains, for example, parity bit checks. Similarly, the operating system is predicated on certain standards for data and file handling. Furthermore, each computer program handles data in a different manner.
Computer facial animationComputer facial animation is primarily an area of computer graphics that encapsulates methods and techniques for generating and animating images or models of a character face. The character can be a human, a humanoid, an animal, a legendary creature or character, etc. Due to its subject and output type, it is also related to many other scientific and artistic fields from psychology to traditional animation.
Polygon (computer graphics)Polygons are used in computer graphics to compose images that are three-dimensional in appearance. Usually (but not always) triangular, polygons arise when an object's surface is modeled, vertices are selected, and the object is rendered in a wire frame model. This is quicker to display than a shaded model; thus the polygons are a stage in computer animation. The polygon count refers to the number of polygons being rendered per frame.
Training simulationIn business, training simulation is a virtual medium through which various types of skills can be acquired. Training simulations can be used in a variety of genres; however they are most commonly used in corporate situations to improve business awareness and management skills. They are also common in academic environments as an integrated part of a business or management course. The word simulation implies an imitation of a real-life process, usually via a computer or other technological device, in order to provide a lifelike experience.
NURBSLes B-splines rationnelles non uniformes, plus communément désignées par leur acronyme anglais NURBS (pour Non-Uniform Rational Basis Splines), correspondent à une généralisation des B-splines car ces fonctions sont définies avec des points en coordonnées homogènes. Le principal intérêt de ces courbes NURBS est qu'elles parviennent même à ajuster des courbes qui ne peuvent pas être représentées par des B-splines uniformes.
Computer representation of surfacesIn technical applications of 3D computer graphics (CAx) such as computer-aided design and computer-aided manufacturing, surfaces are one way of representing objects. The other ways are wireframe (lines and curves) and solids. Point clouds are also sometimes used as temporary ways to represent an object, with the goal of using the points to create one or more of the three permanent representations. If one considers a local parametrization of a surface: then the curves obtained by varying u while keeping v fixed are coordinate lines, sometimes called the u flow lines.
