Where can I find a tutorial/example or help on "Octree" with XNA?

Question

I am developing a small minecraft style game on XNA. I generates a voxel mode, so I'm looking to be optimized to the maximum my matrix "World"! This is the one I'm looking for example "How to Use Octree with Xna ?." Unfortunately, I have not found a tutorial on this on google or other ... I find this strange, because this technology is much used!

I wish I could turn my 100x100x100 matrix containing for each box a bit (1 or 0) indicating whether or not there is a block. Is this a tutorial "Octree" I need to do this? Or can someone show me an example of a transformation matrix3D to a Octree matrice ?

Thousand thank you.
