hdelaunay: Hyperbolic Delaunay triangulation

In stla/gyro: Hyperbolic Geometry

Hyperbolic Delaunay triangulation

Description

Computes the hyperbolic Delaunay triangulation of a set of points.

Usage

hdelaunay(points, model = "M")

Arguments

points	points in the unit disk given as a numeric matrix with two columns
model	the hyperbolic model, either "M" (Möbius model, i.e. Poincaré model) or "U" (Ungar model, i.e. hyperboloid model)

Value

A list with five fields vertices, edges, triangles, ntriangles, and centroids, a matrix giving the gyrocentroids of the triangles. The input points matrix and the output vertices matrix are the same up to the order of the rows if model="M", and if model="U", the points in the output vertices matrix are obtained by isomorphism.
