Project Description

Pure Python tessellation of points into polygons, including Delauney/Thiessin, and Voronoi polygons. Built as a convenient user interface for Bill Simons/Carson Farmer python port of Steven Fortune C++ version of a Delauney triangulator.


Tested on Python version 2.x.


Pure Python, no dependencies.

Installing it

Pytess is installed with pip from the commandline:

pip install pytess


To triangulate a set of points, simply do:

import pytess
points = [(1,1), (5,5), (3,5), (8,1)]
triangles = pytess.triangulate(points)

And for voronoi diagrams:

import pytess
points = [(1,1), (5,5), (3,5), (8,1)]
voronoipolys = pytess.voronoi(points)

I just made it more convenient to use for end-users and uploaded it to PyPi. The real credit goes to Bill Simons/Carson Farmer and Steven Fortune for implementing the algorithm in the first place.
