Terrain Approximating Flat zones

I think it similar to this… but I believe I have to find a way group my points relative to angles as angles taken from surfaces are not exact .
I think it is more like

  1. sorting points
  2. grouping them with angle ranges. For example all points which fall between 0-10 degrees one branch
    10-20 second and so on
  3. Sort list of my split surfaces using these groups and BANG !!!
