Crucially, this distribution of border points is agnostic of routing speed profiles. It’s based only on whether a road is passable or not. This means the same set of clusters and border points can be used for all car routing profiles (default, shortest, fuel-efficient) and all bicycle profiles (default, prefer flat terrain, etc.). Only the travel time/cost values of the shortcuts between these points change based on the profile. This is a massive factor in keeping storage down – map data only increased by about 0.5% per profile to store this HH-Routing structure!

Back in 2024 I learned about SDF (signed distance field) rendering of fonts. I was trying to implement outlines and shadows in a single pass instead of drawing over the text multiple times in different styles. I intended to use these fonts for two different projects, a game and a map generator. I got things working but didn’t fully understand why certain things worked or didn’t work. I wrote some notes on my site about what I tried. In the end, I stopped working on both the game’s fonts and the map generator, so I put all of this on hold.
