Lines, circle, arcs, characters curves are drawn with closely spaced pixels. A picture is constructed from hundreds of such pixels. It is the smallest picture unit accepted by display devices. The term pixel is a short form of the picture element. Some are performed using various combinations of hardware, firmware, and software. Some are performed using hardware or firmware. Some algorithms are implemented using the software. The algorithms implementation varies from one computer system to another computer system. The process of converting is also called as rasterization. Algorithms can develop a higher level of graphical objects.Įxamples of objects which can be scan converted.Using algorithms memory can be used efficiently.Algorithms can generate graphics objects at a faster rate.Advantage of developing algorithms for scan conversion For generating graphical object, many algorithms have been developed. Most human beings think graphics objects as points, lines, circles, ellipses. Using this ability graphics computer represent picture having discrete dots.Īny model of graphics can be reproduced with a dense matrix of dots or points. The circuitry of the video display device of the computer is capable of converting binary values (0, 1) into a pixel on and pixel off information. Each pixel can have either on or off state.
It is a process of representing graphics objects a collection of pixels.
