Vector graphics

Is the use of simple geometrics such as points, lines, curves and shapes or polygons which are all based on mathematical equations to represent images in computer graphics. Computer displays are made up from grids of small rectangular cells called pixels. The picture is built up from these cells. The smaller and closer the cells are the better qaulity of the image. If you enlarge bitmap images they become Pixelated however Vectors are not made up of cells so therefore do not become pixelated.

Any software to do with vector is called a drawing programme for example CAD computer aided design.
