octree explanation please

[Ademord]

hello i messaged with you a bit on youtube and on the unity forums. first of all i want to say thanks for making the code available, i am running it and reverse engineering it in my computer since saturday.

i was wondering if you could help me out understand what did you do in the octrees with the octants and the leaf nodes. I have never used these data structures, looked at a lot of tutorials so I get them now, but I would highly appreciate it if you could help me understand what the underlying concept is, maybe some diagram...
