I believe I have verified that the terrain is at the correct scale.<\/p>\n

Testing this is obviously difficult, since manually traversing a realistic sized terrain is not possible. However, I placed the player at a point on the terrain, and then moved the players world position, to a point 90 degrees offset from that point, still on the terrains surface. In effect, the player had travelled from the north pole, to a point on the equator. When I did this, the terrain immediately updated to show the new subdivided nodes, in the correct position on the terrain.<\/p>\n

I will need to do more testing on this. I am currently working on plotting more points on the surface of the terrain, and I will also need to take into account the players 32-bit position in addition to their world space position to properly update the terrain nodes. I do think I am very close with this solution, and there will hopefully not be any major problems remaining.<\/p>\n

The next goal is to further subdivide the remaining nodes to simply improve quality and smoothness. I can then work on extending the LOD system to very long ranges, so that the player can travel from the surface to a point in space where the terrain is no longer visible. I also need to fix the player collision system, and extend it to handle non-player objects, such as AI players, environment objects, precipitation, etc.<\/p>\n
