I get way more use out of Doubly Connected Edge Lists (DCEL) than I ever thought I would when I first learned about them in school.
When I want to render simple stuff to the screen, built-in functions like 'circle' or 'line' work. But for any shapes more complicated than that, I often find that it's useful to work with the data in DCEL form.
