Pandas to 3D Model

Pandas to 3D Model is written in Python 3.x.

Python 3 and libraries

Virtualenv:

$ sudo pip install virtualenv
$ virtualenv --no-site-packages env

Matplotlib binary dependencies: https://matplotlib.org/users/installing.html#macos

$ xcode-select --install
$ # (for subprocess32)
$ python3 -m pip install matplotlib
$ # Docs say...
$ python3 -mpip install -U pip
$ python3 -mpip install -U matplotlib

Pandas: http://pandas.pydata.org/

$ python3 -m pip install pandas

Usage

To run the tests (which generate output)

$ source env/bin/activate
$ python3 -m pip install --user '.'
$ python3 -m unittest discover '.'

To avoid this: Command "python setup.py egg_info" failed with error code 1 in Start with:

export LC_ALL=en_US.UTF-8
export LANG=en_US.UTF-8

Output

3D scatter plot using matplotlib:

3D scatter plot to a Wavefront .obj: (Screen shot from Blender)

5k.rect.normal.ascii from http://www.cs.du.edu/~leut/MultiDimData.html

To view the .obj files

$ python3 -m http.server
