Distance fields can be used to draw almost everything. Obviously the more complex a shape is, the more complicated its equation will be, but once you have the formula to make distance fields of a particular shape it is very easy to combine and/or apply effects to it, like smooth edges and multiple outlines. Because of this, distance fields are popular in font rendering, like [Mapbox GL Labels](https://www.mapbox.com/blog/text-signed-distance-fields/), [Matt DesLauriers](https://twitter.com/mattdesl) [Material Design Fonts](http://mattdesl.svbtle.com/material-design-on-the-gpu) and [as is describe on Chapter 7 of iPhone 3D Programming, O’Reilly](http://chimera.labs.oreilly.com/books/1234000001814/ch07.html#ch07_id36000921).
