"Vector graphics is the use of geometrical primitives such as points, lines, curves, and polygons—all of which are based on mathematical expressions—to represent images in computer graphics. Vector graphics are based on vectors (also called paths), which lead through locations called control points or nodes. Each of these points has a definite position on the x and y axes of the work plane and determines the direction of the path; further, each path may be assigned a stroke color, shape, thickness, and fill. Vector graphics can be magnified infinitely without loss of quality, while pixel-based graphics cannot." .
Because vector graphics are basically a collection of mathematical expressions, it is relatively easy to write programs to produce high-quality vector images. These images are also easy for machines such as laser cutters and CNC tools to translate into position and motion descriptions.
