While doing computational geometry research with Professor Pankaj K. Agarwal and Thomas Mølhave at Duke, we looked at using quadtrees and the well-separated pairs decomposition (WSPD) for one of our algorithms. As I was reading about the algorithms and geometric concepts, I decided to code them in Javascript and HTML5′s canvas to get more intuition [...]
