That doesn't make any sense to me (although I wish it was true, life
would be easier). Maybe in your particular application you don't need to
worry about this, but then your terrains musnt be very big AND you must
be targetting some powerful T&L hardware.

In any case, some simple techniques like VIPM with bounded pixel error
are almost always an easy win.

engines, PVSs and D3D vs OpengGL? :)
