This implementation is based on PyMCubes. The original implementation outputs only list of vertices and facets (V, F). mcube-neo additionary implements algorithm to find connected components of the mesh. So, in addtion to (V, F), we can obtain the information of which facet to belong to which groups. The implementation that I added/modified is mainly be found in tablemanager.h. Another difference from the original is that, we use pybind11 rather than pure python wrapper, which enables us to easily write a fast wrapper.

Installation will be done by the following commands:

git clone https://github.com/HiroIshida/mcube-neo
cd mcube-neo
git clone https://github.com/pybind/pybind11
mkdir build
cd build
cmake .. -DPYTHON_EXECUTABLE=$(which python)
# cmake .. -DPYTHON_EXECUTABLE=$(which python) -PYTHON_GLOBAL_SITE_PKG=ON # if want to install to global site package
make
make install

A simple usage example can be found in test.py. The following image is the output of the script. You can see that component is decomposed into different connected polygons, and plotted with different colors.
