earcut-rs

Test codecov Crates.io Version

A Rust port of the mapbox/earcut polygon triangulation library.

  • Based on the latest earcut 3.0.2 release.
  • Designed to avoid unnecessary memory allocations. Internal buffers and the output index vector can be reused across multiple triangulations.
  • An additional module, utils3d, can project 3D coplanar polygons onto a 2D plane before triangulation.
  • License: ISC

Measured on a MacBook Pro (M1 Pro).
