Realistic artificial dendrites using minimum spanning trees and Blender 3D. A short tutorial on how to use it can be found here.
mstree.py gives access to functions for creating minimum spanning trees with balancing factor. The work is based on a paper for synthetic neuronal structures by Hermann Cuntz. Given a set of points, the algorithm calculates a minimum spanning tree on them.
mst_blender is an addon for Blender 3D to create minimum spanning trees directly in Blender.
To install, copy the mst_blender folder into your Blender script directory (minimum Blender version 2.70/2.80).
Two new GUI-Panels will show up in your Tools panel, where you can adjust settings for your MST.
As of Blender 2.80, you will find the operators in Add->Mesh->Minimum Spanning Tree.
This addon was mainly developed to create Dendritic structures in Blender as a bachelor thesis, but it can be used to just create minimum spanning trees when using a balancing factor of 0.
