[Addon] Minimum Bounding Volume

Coding Released Scripts and Themes
1

Purpose:
An addon to calculate the aproximate minimum bounding box of objects

Useage:

  1. Download source from GitHub
  2. Unzip into Addons directory or install from .zip
  3. Select a MESH object
  4. “SpaceBar” menu -> “Min Bounding Box”
  5. Adjust variables as desired in props popup dialogue
  6. A new mesh obeject (box) will be added to the scene, with it’s local axes aligned with the faces of the min bounding box.

ToDo: (Feel free to fork repo and tackle a task)
Non Mesh objects
Editmode work on selected geometry
Optionally modify original object orientation to match bounding box
Optionally add a bone aligned with the box
Organize props/variables in popup dialogue

Optimize the PCA algorithm to project coords to solve the 2d problem in 2d instead of 3d (speed increase)
Combine all 3 PCA axes tests into a single test

This is really cool!

What is the real need for a box on an object ?

  1. efficient intersection testing with less false positives
  2. nesting objects together for milling or other CAM related functions
  3. Decreased packaging and shipping costs
