Flow Field Pathfinding


You may know me for my interactive tutorials. But before that, I was writing visual but non-interactive tutorials.

In particular, there wasn’t a lot of information about A* on the web, so I decided to collect all my notes about pathfinding[1] together in one place in the 1990s. I felt like the early papers about it conflated the flow fields with hierarchical pathfinding, but I wasn’t sure, and I didn’t want to write about it until I was sure. Although I mention hierarchical pathfinding[8] in these notes, I don’t cover it in detail.
