I don't realy understand that you want , but I think you talk about a Terrain LOD ... But I think Blitz a not any powerfull to make a Dynamic Terrain Lod with it (the terrain blitz are dynamic, but they aren't really like a mesh).... and the TRaingle creation are not enough good to do it ...
Actually there is more Algo to create a Dynamic Terrain, ROAM and QuadTree
