We use a ROAM-like algorithm. See class CLandscape for more details. It is
based on bezier patchs, not on heightmap, so it is slighty different from
ROAM (as example, you can't deduce tesselation neighborhood from topology (a
patch graph is not as simple as a heightmap :) )). There is lot of features
(from Tiles, to distance based geomoprh) which make it different from the
original ROAM document.

Actually, I tink the only thing copied from ROAM is the triangle split/merge
scheme.
