Flashcards: Computer graphics

Digital art is an artistic work or practice that uses digital technology as an essential part of the creative or presentation process.

Raster images are stored in a computer in the form of a grid of picture elements, or pixels.

A framebuffer (frame buffer, or sometimes framestore) is a portion of RAM containing a bitmap that is used to refresh a video display from a memory buffer containing a complete frame of data.

Supersampling is a spatial anti-aliasing method, i.

In computer graphics, ray tracing is a technique for generating an image by tracing the path of light through pixels in an image plane and simulating the effects of its encounters with virtual objects.

Computer-generated imagery (CGI) is the application of computer graphics to create or contribute to images in art, printed media, video games, films, television programs, shorts, commercials, videos, and simulators.

Turtle graphics is a term in computer graphics vector graphics using a relative cursor (the "turtle") upon a Cartesian plane.

In image processing and photography, a color histogram is a representation of the distribution of colors in an image.

OpenGL Shading Language (abbreviated: GLSL or GLslang), is a high-level shading language based on the syntax of the C programming language.

In linear algebra, linear transformations can be represented by matrices.

In digital imaging systems, color management is the controlled conversion between the color representations of various devices, such as image scanners, digital cameras, monitors, TV screens, film printers, computer printers, offset presses, and corresponding media.

In computer graphics and digital imaging, scaling refers to the resizing of a digital image.

In computer displays, filmmaking, television production, and other kinetic displays, scrolling is sliding text, images or video across a monitor or display, vertically or horizontally.

In computing, an avatar is the graphical representation of the user or the user's alter ego or character.

Video tracking is the process of locating a moving object (or multiple objects) over time using a camera.

In computer graphics, a color gradient (sometimes called a color ramp or color progression) specifies a range of position-dependent colors, usually used to fill a region.

A vertex (plural vertices) in computer graphics is a data structure that describes certain attributes, like the position of a point in 2D or 3D space, at multiple points on a surface.

Terrain rendering covers a variety of methods of depicting real-world or imaginary world surfaces.

This is a list of color palettes of some of the most popular early 8-bit personal computers and terminals, roughly those manufactured from 1975 to 1985.

Visual computing is a generic term for all computer science disciplines handling with images and 3D models, i.

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.

Computer graphics is a sub-field of computer science which studies methods for digitally synthesizing and manipulating visual content.

Visualization or visualisation (see spelling differences) is any technique for creating images, diagrams, or animations to communicate a message.

This is a list of the full color palettes for notable video game console hardware.

Immediate mode rendering is a style for application programming interfaces of graphics libraries, in which client calls directly cause rendering of graphics objects to the display, or in which the data to describe rendering primitives is inserted frame by frame directly into a command list (in the case of immediate mode primitive rendering), without the use of extensive indirection to retained resources.

Video overlay is any technique used to display a video window on a computer display while bypassing the chain of CPU to graphics card to computer monitor.
