Whats best for terrain engines

Whats the best way to optimize a terrain engine? Ive been testing some techiniques I didnt found nothing that looks like flight simulator 2002 terrain engine.

ROAM/C-LOD with basic frustum culling

check out the resources at gamedev.net under Game Programming. they have several articles on landscape and terrain engines.


That depends on what you want to do.For a small terrain(say 1024x1024 for example) you could easily get away w/ a bruteforce(yuck!) approach on todays cards.But if you’re shooting for larger sizes(say 10k*10k) then nothing can beat a CLOD approach w/ some paging etc.Beware though that such an approach needs heavy optimization to work well,or it might turn out slower than a much simpler method.If you’re just starting I’d recommend Bryan Turner’s implementation of split-only at gamasutra.
