In this post, you will learn how to Voronoi any mesh using steps that I found from this video:
i. Blender (http://www.blender.org/download)
ii. Meshlab (http://sourceforge.net/projects/meshlab/files/meshlab/MeshLab%20v1.3.2/)
1. Import your stl into Meshlab.
(Note: Meshlab lets you import other files than stl's, however stl is the format that I personally prefer to work with.)
2. Look at the number of faces your and vertices your object has. This can be found at the bottom of your Meshlab window.
These values seem to produce an adequate effect for what I have hoped to achieve in the past. If you have run this tutorial and you have problems, or it's not coming out as nice as you'd like, you may have too few faces. To solve this, open up Blender.
1. Import your stl
2. Change from Object Mode to Edit Mode
3. Hit 'A' On your keyboard to deselect everything, then hit 'B' to select the vertices of the faces you wish to subdivide. look in your mesh tools menu (on the left) and click subdivide. After getting a fairly equal subdivision across the surface of your mesh, you are ready to move on to working with Meshlab.
