Gouraud shading
Gouraud shading is a method used in computer graphics to simulate the differing effects of light and colour across the surface of an object. In practice, Gouraud shading is used to achieve smooth lighting on -
Ray tracing
Ray tracing is a general technique from geometrical optics of modelling the path taken by light by following rays of light as they interact with optical surfaces. It is used in the design of optical -
Rendering
Rendering is the process of generating an image from a model, by means of a software program. The model is a description of three dimensional objects in a strictly defined language or data structure. It -
Sprite
In computer graphics, a sprite is a two-dimensional image or animation that is integrated into a larger scene. Sprites were originally invented as a method of quickly compositing several images together in two-dimensional -
Anti-Aliasing
In digital signal processing, anti-aliasing is the technique of minimizing aliasing (jagged or blocky patterns) when representing a high-resolution signal at a lower resolution. In most cases, anti-aliasing means removing data at -
3D computer graphics
Template:Cleanup-date The rewrite of this article is being devised at Talk:3D computer graphics/Temp. Please comment or help out as necessary. Thanks! 3D computer graphics are works of graphic art that were -
Transparency
Template:Otherusesof Transparency is possible in a number of graphics file formats. The term transparency is used in various ways by different people, but at its simplest there is "full transparency" i.e. something that -
Fractal
Objects that are now called fractals were discovered and explored long before the word was coined. In 1525, the German Artist Albrecht Durer published The Painter's Manual, in which one section is on "Tile -
Direct3D vs. OpenGL
In computer software, Direct3D is a proprietary API designed by Microsoft Corporation that provides a standardized API for hardware 3D acceleration on the Windows platform. Direct3D is implemented, like OpenGL on the same platform, in -
2D computer graphics
2D computer graphics is the computer-based generation of digital images—mostly from two-dimensional models (such as 2D geometric models, text, and digital images) and by techniques specific to them. The word may stand -
Phong shading
Template:Mergefrom The term Phong shading is used indiscriminately to describe both an illumination model and an interpolation method in 3D computer graphics. -
Texture mapping
Texture mapping is a method of adding realism to a computer-generated graphic. An image (the texture) is added (mapped) to a simpler shape that is generated in the scene, like a decal pasted to -
Image processing
In the broadest sense, image processing is any form of information processing for which both the input and output are images, such as photographs or frames of video. Most image processing techniques involve treating the -
Digital art
Digital art is art created on a computer in digital form. Digital art can be purely computer-generated, such as fractals, or taken from another source, such as a scanned photograph, or an image drawn -
Radiosity
Radiosity is a global illumination algorithm used in 3D computer graphics rendering. Unlike direct illumination algorithms (such as Ray tracing), which tend to simulate light reflecting only once off each surface, global illumination algorithms such -
Affine transformation
In geometry, an affine transformation or affine map (from the Latin, affinis, "connected with") between two vector spaces consists of a linear transformation followed by a translation: In the finite-dimensional case each affine transformation -
Computer-generated art
Computer-generated art is art created with a computer. The term is usually applied to works created entirely with a computer. It is a subset of digital art. Movies make heavy use of computer-generated -
Refraction
Refraction is the change in direction of a wave due to a change in its velocity. This is most commonly seen when a wave passes from one medium to another. Refraction of light is the -

Conversion between quaternions and Euler angles
Spatial rotations in three dimensions can be parametrized using both Euler angles and unit quaternions. This article explains how to convert between the two representations. Actually this simple use of "quaternions" was first presented by -
Radiance
Radiance and spectral radiance are radiometric measures that describe the amount of light that passes through or is emitted from a particular area, and falls within a given solid angle in a specified direction. They -
Truecolor
Template:Color depth Truecolor (known as Millions by Apple Computer) graphics is a method of storing image information in a computer's memory such that each pixel is represented by three or more bytes. Generally -
Alpha blending
Alpha blending Often, a fourth component is added to color models. The fourth component is called alpha, andcolor models that use it are referred to by names such as RGBA and HSLA. Alpha is not -
Flat shading
Flat shading is lighting technique normal and the direction of the light source, their respective colors and the intensity of the light source. It is usually used for high speed rendering where more advanced shading -
Scaling
in computer graphics, refers to altering the size of a sprite to make the sprite appear nearer or farther from the player's point of view. It is a transformation that change the size or
