Just a question: What kind of reasons were that?
Simplicity. Stability. CPU usage. Rendering performance. Ease of development and maintenance. Robustness in the face of non-heightmap geometry features (roads, airport cutouts). Texture memory usage (LOD algorithms tend to require unique texturing). The list goes on and on.
CLOD algorithms are nifty and elegant. But they ain't easy. They
tend to work a lot better as isolated demos than they do as platforms
for future development.
Right, and then try scaling that nifty CLOD demo of a small area to now seamless cover the entire world and allow uninterrupted flights from any point to any point. From what I hear, this is certainly doable, and the major issues can be addressed, but it's a lot of work and no one has yet tackled this in the context of FlightGear.
