Dr. Bresenham was my graphics instructor. When I later talked to other people who took graphics in college - their school had them transforming & scaling images, doing image recognition, animating scenes and so on. We drew lines and circles -- very very quickly. :)

It's also where I learned that compiler maturity matters. Everyone else in the class used Turbo Pascal. I used the then-new Turbo C (yes, plain C), and ended up with 1/3 the performance of their code.
