New on CTAN: luahyperbolic

Damien Mégy submitted the luahyperbolic package. Version: 2026-03-16 License: cc0 Summary description: Hyperbolic geometry in the Poincaré disk model Announcement text:

---

This package allows to draw pictures and do computations in plane hyperbolic geometry, in the Poincaré disk model. Computations are done with Lua, and graphics are generated with TikZ. The package is written in Lua and requires lualatex. Features: Draw geodesic lines, segments, polygons, rays, circles, horocycles, hypercycles. Label and mark segments, angles compute intersections of geodesics, circles, symmetries, reflections, exponential maps, automorphisms Draw hyperbolic triangle tilings with a simple LaTeX macro Example tiling : https://raw.githubusercontent.com/dmegy/luahyperbolic/refs/heads/main/triangle-tiling-2-4-5.png
