A Tour in the Wonderland of Math with Python


A collection of python scripts for drawing beautiful figures and animating interesting algorithms in mathematics.


Build Status


About this repo

The purpose of this project is to show the beauty of math with python. It consists of several independent sub-projects. The topics are chosen largely due to my personal taste:

  1. They must produce appealing results.
  2. There must be some non-trivial math behind them.
  3. The code should be as simple as possible.

I'll use only popular python libs and build all math stuff by hand (tools like sage, sympy, mathemetica will not be used here). Also I only maintain the code for python >= 3.5.

The website for the docs is still under construction and will be released soon.

A few examples:

How to use

Each subdirectory in /src/ is a single program (except that glslhelpers is a helper module for running glsl programs and misc is a collection of independent scripts), any file named main.py, run_*.py, example_*.py is an executable script that gives some output.

List of algorithms

Here is a list of some algorithms implemented in this project:

Dependencies

The recommended way to install all dependencies is simply running the script install_dependencies.sh.

Or you can install the python libs by pip:

pip install -r requirements.txt

A few exceptions are: cairocffi also requires libffi-dev and pygraphviz also requires libgraphviz-dev:

sudo apt-get install libffi-dev libgraphviz-dev

Open source softwares:

  • python3-tk (for file dialog)
  • ImageMagick (for making gif animations)
  • FFmpeg (for saving animations to video files)
  • POV-Ray (for generating high quality raytracing results)
  • graphviz (for drawing automata of Coxeter groups)

They can all be installed via command-line:

sudo apt-get install python3-tk imagemagick ffmpeg povray graphviz

In the scripts these softwares are called in command line by povray, ffmpeg, convert, etc. For Windows users you should add the directories contain these .exe files to the system Path environment variables. For example on Windows the default location of POV-Ray's exe file is C:\Program Files\POV-Ray\v3.7\bin\pvengine64.exe, so you should add C:\Program Files\POV-Ray\v3.7\bin to system Path and rename pvengine64.exe to povray.exe, then you can run the scripts without any changes and everything works fine.
