RE: [Algorithms] Terrain performance comparrisons

[Tom F. <to...@mu...>]

If time is short, try Grek Snook's version in Games Programming Gems 2. It
is startlingly simple, and gets you easily 90% of the benefit of any of the
other routines over having no LOD, and it's very quick. Because it is so
simple (i.e. dumb) it works fine with dynamic terrains.
