Quadtree level of detail system

I’m looking to create a level of detail system similar to this video:


I’ve never attempted this in Unity but I was wondering how I would start going about this? I know there are LOD Groups in Unity but I don’t just want pre-made LOD models, I’m wanting to create the plane procedurally then break it up into chunks to load in runtime.

Start here http://docs.unity3d.com/Documentation/ScriptReference/GL.html,

You can use the GL calls for the rendering of your procedurally generated data and manage it with your own LOD class. Make sense?
