The package 2D Hyperbolic Triangulation provides Delaunay triangulations
in the Poincaré disk model of the hyperbolic plane, complete with demos, 
examples, and tests. The hyperbolic Delaunay triangulation defined by a 
set of points in the Poincaré disk model is a simplicial sub-complex of 
the Euclidean Delaunay triangulation defined by the same set of points in 
the unit disk centered at the origin of the Euclidean plane. More information
