Vector art is any digital artwork in which the shapes in the art are represented by mathematical equations within a computer. Geometric shapes like lines, waves, single points and curves are placed together by the artist to create an illustration while the computer keeps track of each item’s location, curve and relative proportion to the other shapes.
The biggest advantage of vector art is that it is infinitely scalable. Unlike raster art, which uses pixels to create digital illustrations, vector-based artwork can be enlarged over and over again without losing any of the picture’s quality. Another advantage of vector art is that, unlike raster art, the work created always takes up the same amount of memory in your computer. This means that you can create images as large as you want and still not have it affect the file size of your digital illustration. With raster artwork, larger images mean much larger file sizes
Due to the distinctive properties of vector art, it is applied to very specific types of illustration. Creating logos and text are the most common applications for vector art. These images often need to be scaled up or down in size in a wide variety of ways for publication and marketing purposes. This necessitates the ability to zoom in or out without losing any image quality.
