This allows even basic home systems to support advanced 3D games and applications. Now most computers now come with a 3D video card that handles all the 3D processing. By the year 2000, many video games had begun incorporating 3D graphics, since computers had enough processing power to support them. In computer graphics, rasterisation (British English) or rasterization (American English) is the task of taking an image described in a vector graphics format (shapes) and converting it into a raster image (a series of pixels, dots or lines, which, when displayed together, create the image which was represented via shapes). Unlike raster graphics, vector graphics can be scaled to a larger size without losing quality.ģD graphics started to become popular in the 1990s, along with 3D rendering software such as CAD and 3D animation programs. They are often used for creating logos, signs, and other types of drawings. Vector graphics, on the other hand are made up of paths, which may be lines, shapes, letters, or other scalable objects. They are composed of a simple grid of pixels, which can each be a different color. Raster graphics are the most common and are used for digital photos, Web graphics, icons, and other types of images. While the first machines only supported 16 or 256 colors, most computers can now display graphics in millions of colors.ĢD graphics come in two flavors - raster and vector. Eventually, computers began to support color images. Early computers only supported 2D monochrome graphics, meaning they were black and white (or black and green, depending on the monitor). Graphics are often contrasted with text, which is comprised of characters, such as numbers and letters, rather than images.Ĭomputer graphics can be either two or three-dimensional. Therefore, computer graphics are simply images displayed on a computer screen. A graphic is an image or visual representation of an object.
