Simple interface to MeshPy / TetGen in Blender

Warning this project is likely abandoned. The original purpose required the output of Voronoi meshes from TetGen - since MeshPy does not support the -v flag to do this, the goal is no longer possible.

Check out the related visualization add-on for TetGen in Blender: TetGen Viz Blender. This uses the raw output files directly from TetGen.

Installation

Tested with Blender 2.79.

We need the MeshPy python module. The best method is: (1) identify the Python version Blender is using, (2) install MeshPy for that version in a separate virtual environment Python (see here), (3) copy over the module.

1. Identify Python version: Navigate to the directory - on a Mac it is probably /Applications/Blender/blender.app/Contents/Resources/2.79/python/bin/. Check the exact version with ./python3.5m --version - here it is 3.5.3.

2. Install MeshPy for that version (see here). Using conda (from any directory):

• Create the virtual environment: conda create --name conda-python-blender python=3.5.3.
• Activate: source activate conda-python-blender.
• Install MeshPy: pip install MeshPy. Probably you will also be prompted to install pip install pybind11.
• Find the directory for the module: echo "import sys; print(sys.path)" | python. It should be something like: ~/anaconda3/envs/conda-python-blender/lib/python3.5.3/site-packages.
• Copy over the module: cp -r ~/anaconda3/envs/conda-python-blender/lib/python3.5.3/site-packages/MeshPy* /Applications/Blender/blender.app/Contents/Resources/2.79/python/lib/python3.5/site-packages/.
