The rise of vector graphics.
Some of the first types of computer graphics were vectors, as the computational power necessary to create raster images was too expensive. Early computers used vector displays in the 1960s and ’70s; video games like 1979’s Asteroids also used vector graphics. This practice continued until the 1980s, by which point most displays had switched to raster graphics.
Due to the need for art that prints at multiple sizes and responsive web designs that adapt to varying screen sizes, vector files are a necessity of modern design. They create clean, scalable images that allow for exciting visual possibilities with the added bonus of functionality.
Modern typography is almost exclusively created using vectors. The text you’re looking at right now is a product of vector graphics. 3D modeling and the computer graphics (CG) we see in blockbuster superhero films are the direct consequence of developments in vector art and illustration.
Why are vector graphics and artwork needed?
Vector graphics and artwork is clean, camera-ready and can be scaled infinitely without loss of quality. Lower resolution files don’t offer the same display standard – whether digitally or printed.
Bitmap file formats are a perfect example of this. For example, whenever a .PDF, a .JPG or a .GIF file is resized for an artwork, it will generally become more jagged in its appearance. Pixels become more prominent and the result is a blurry, poor-quality end product.
By using vector graphics, you can display artwork as big or small as it needs to be. Vector graphics can be saved as .AI, .EPS and .CDR. Using these file formats will enhance the quality of your work and make design and illustration much more simple.
