Example showing effect of vector graphics and raster graphics. The original vector-based illustration is at the left. The upper-right image shows a magnification of 7x as a vector image. The lower-right image shows the same magnification as a bitmap image. Raster images are based on pixels. They scale with loss of clarity. Vector-based images can be scaled indefinitely without degrading.

Vector graphics (also called graphical modeling, or object-oriented graphics) is a type of computer graphics. Vector graphics uses geometrical objects, like points, lines, curves, and polygons to model the image. Mathematics can be used to describe the graphics. Most often vectors and matrices are used. The other way to model computer graphics is to use raster graphics. They model images as a collection of pixels. Most often photographs are modeled as raster images.
