   Geometry Clipmaps
  Does anyone know of a site or have any code that could show how to use Hugues Hoppe's article on Terrain Rendering Using GPU-Based Geometry Clipmaps (the one that uses the gpu and vs 3.0)? I downloaded the scource code, but it is just .fx files. I am trying to learn how to do it but there is no c++ showing how to implament it. anyone have this method implamentedand could show how to use it?   
  This describes the original non-GPU implementation: Geometry Clipmaps: Terrain Rendering Using Nested Regular Grids. It should be easier to understand.
