Delaunay triangulation in the hyperboloid model

[stla]

Just for fun. There is an isomorphism between the Poincaré hyperbolic space and the hyperboloid hyperbolic space. So we can get a Delaunay triangulation in the hyperboloid model by mapping a Delaunay triangulation in the Poincaré model:

(the space is the entire plane, lines are hyperbolas whose asymptotes meet at the origin)
