map_editor/
lib.rs

1//! The map_editor renders and lets you edit RawMaps, which are a format in between OSM and the
2//! full Map. It's useful for debugging maps imported from OSM, and for drawing synthetic maps for
3//! testing.
4//!
5//! TODO It's a bit unmaintained / rarely used. Two big problems using it:
6//! - Intersection geometry isn't recalculated constantly as changes are made
7//! - The app will run out of GPU memory up-front on huge maps, because of storing objects for
8//!   every road and intersections
