With this program you can interactively investigate some polyhedra. I use this program myself and I am willing to share it with other who are interested. I use Ubuntu, as a consequence some problems might exist with windows.

When wxPython is installed through pip it is compiled. This can take quite some time (e.g. more than 15 minutes). This means that there should be c-compiler available at least. For a Debian Linux you would need have installed (e.g. through apt-get) the packages
- build-essential
- libgtk-3-dev and libwxgtk3.0-gtk3-dev (or whathever GTK version you are using)
- python3-dev
- libgl1-mesa-glx libglu1-mesa
The reason for me to choose wxPython over Tk was that I ran into quite some preformance problems with Tk. The disadvantage is that it can be a pain to install wxPython through pip.
Also here it is important to have the correct packages for building wxPython installed. See section wxPython" above.
pip install orbitit
python -m orbitit
You will need:
- python 3.x: http://www.python.org
- wxPython: http://www.wxpython.org
- pyOpenGL: http://pyopengl.sourceforge.net/
E.g. for Ubuntu or other Debian based Linux dist:
sudo apt-get install python3 python3-pip
Then use pip to install other packages, e.g:
pip3 install attrdict3 pip3 install pyopengl wxpython`
See section wxPython for more about installing wxPython through pip.
Make sure the PYTHONPATH points out this directory, e.g. in Linux
export PYTHONPATH=$PWD
Also make sure to have set the PYOPENGL_PLATFORM environment variable.
On my system I do
source ./init_env
python -m orbitit
Use "python -m orbitit -h" for more help on additional parameters. Note that you
can define an environment variable ORBITIT_LIB to point to a library with
models, e.g. the github repo orbitit-lib.
If you get problems with a context not being valid, e.g. OpenGL.error.Error: Attempt to retrieve context when no valid context
Then this might be related to eht wrong PYOPENGL_PLATFORM
In my case this problem was solved by
PYOPENGL_PLATFORM=egl python -m orbitit
If you get problems with NotImplementedError on GLCanvas you probably built wxPython without the wxgtk support. See section wxPython above.
