For manipulating curves and measured laminations on surfaces and producing mapping tori.
Project description
Flipper is a program for computing the action of mapping classes on
laminations on punctured surfaces using ideal triangulation coordinates.
It can decide the Nielsen--Thurston type of a given mapping class and,
for pseudo-Anosov mapping classes, construct a layered, veering
triangulation of their mapping torus, as described by Agol.
Flipper can be run as a Python 2, Python 3 or Sage Python module. Currently
it is fastest as a Sage Python module.
Flipper is available on the Python Package Index (PyPI). The preferred method
for installing the latest stable release is to use pip:
> python -m pip install flipper --user --upgrade
Pip can be installed using get-pip.py from
http://pip.readthedocs.org/en/latest/installing.html
and is included in Python 3.4 by default.
Flipper can also be installed through the older easy_install:
> python -m easy_install flipper
For more information about installing and using flipper see "A users
guide to flipper". Open by running:
> python -m flipper.doc
