Vector-based graphical user interface

A vector-based graphical user interface is a mostly conceptual type of graphical user interface where elements are drawn using vector rather than raster information.

The benefits of a completely vector-based graphical user interface would include:

Cons might include:

Since current 3D Graphics are usually vector-based, rather than raster-based, vector-based graphical user interfaces would be suitable for 3D graphical user interfaces. This is because raster-based 3D models take up an enormous amount of memory, as they are stored and displayed using voxels. Current operating systems such as Windows Vista, Mac OS X, and UNIX-based operating systems (including Linux) have enjoyed much benefit from using 3D graphical user interfaces. In Windows Vista, for example, Flip3D textures each window to a 3D plane based on vector graphics. Even though the window itself is still raster-based, the plane onto which it is textured is vector-based. As a result, the windows, when rotated, appear flat. In Linux desktops, Compiz Fusion can texture each raster-based workspace onto a 3D vector-based cube. As operating systems evolve, eventually the entire window would be made from 3D vector graphics, so that when rotated, it does not appear "flat". Also, advanced lighting may make 3D graphical user interfaces more aesthetically pleasing.

As most computer monitors become more and more high resolution, everything displayed would be smaller. However, if the screen resolution were turned down, everything would appear pixelated. Thus, resolution independence is currently being designed to solve this problem. With raster graphics, all icons need to be extremely high resolution, so as to not appear pixelated on higher resolution screens. This may take up enormous amounts of memory, and hard disk space. If vector graphics were used instead, it could be easily scalable and never lose data nor appear pixelated.
