Scan Conversion Algorithms Quiz

The geometric objects that need to be represented in a 2-D grid are points, lines, curves, and polygons.

In display systems, a raster is a series of adjacent parallel lines that together form an image on a display screen. It is a rectangular grid or an array of pixel positions.

Random scan and raster scan are two different methods used in display systems. In random scan, the electron beam directly writes the picture on the screen, while in raster scan, the picture is created by scanning the electron beam across the screen in a series of horizontal lines.

Scan conversion is a general term for drawing methods that create raster images according to given picture 'primitives'. It is used for drawing images based on predefined shapes or objects.

Pixels, short for picture elements, are the smallest individual units of a digital display. They are independently colored and together form the lines that make up the raster image.
