    Summary description: Hyperbolic geometry in the Poincar|- disk model

    Announcement text: --------------------------------------------------------------------------------

    This package allows to draw pictures and do computations in plane hyperbolic geometry, in the Poincar|- 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
