New algorithm triangulates 3.7 million map polygons in under half a second

Original: Faster than earcut: triangulating 3.7M map polygons in 489 ms Article URL: https:// globus.software/blog/2026/10/1 6/cut

Globus Software has published a blog post describing a polygon triangulation method it says is faster than the widely used earcut library, processing 3.7 million map polygons in 489 milliseconds. The write-up details the technique for cutting map polygons, and the performance claim is drawing attention among developers interested in geometry and mapping performance.

Why now: Developers interested in mapping and computational geometry are discussing the claimed speed improvement over the popular earcut library.
