 You have seen GeoMipMapping implemented in games before. This is where the farther away terrain has fewer polygons, and as you move closer, more polygons fill in. The whole terrain is divided into a grid of patches, and each one has its own level of detail (LOD). The GeoMipMapping algorithm looks at each patch, and its neighbours, to determine how to render the geometry. It will seam the edges between two patches with different LOD.
