From the Simple English Wikipedia, the free encyclopedia that anyone can change
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.
